    面对外部国际需求萎缩,内部支撑经济高速增长的传统人口红利、资源环境红利等逐渐衰减,中国经济增长将面临逐步回落到中低增速的“新常态”。从经济地理学角度开展针对中国经济新常态这一新事像及其格局研究具有重要意义。以全国31个省区单元(港澳台除外)为研究尺度,通过关键指标,分析了中国经济新常态的格局态势,开展了类型划分。结果表明:近年来,中国财政收入、电力消费量、铁路货运量指标,主要行业门类,以及投资、出口和消费的增速均呈现明显下降,绝大多数省区与全国发展态势保持一致。将全国31个省区划分为较快增长、下行压力较小和下行压力较大3类区域,下行压力较大区域细分发展阶段型、整体衰退型、能源原材料型以及其他等4种类型,不同类型区域具有明显的地理集聚特征。针对这一轮经济下行风险,不同地区应采取不同的对策,重点关注东北区域的整体衰退风险,以及山西等省能源原材料省区的经济下行风险。


    In face of the decreasing external demand and the population, resources and environment bonuses, the economic growth in China will gradually dipped to a low growth. The researches on objects and pattern of China’s ‘New Normal’ from the view of Economic Geography have great influence on the development of China. Through certain key indexes, this article focused on the trend of economy and the regional type in the 31 provinces of China. The results indicated that: In the past few years, the growth rate of fiscal revenue, electricity consumption, and volume of railway freight has declined sharply, and meanwhile, many primary industries and ‘three carriages’ (fixed asset investment, export, and total retail sales of consumer goods) as well. Many provinces have the same tendency as the whole China. Moreover, the total 31 provinces are divided into three types: relatively fast growth, light downward pressure, and great downward pressure individually. Provinces with great downward pressure are further divided into four types: developing regions, overall declining regions, energy-owned regions, and others.The same type of regions is geographic agglomeration obviously. Faced with this round of economic downside, different regions should take different measures, and the developing risks of Northeast China and energy-owned regions such as Shanxi should be emphasized on.

    中国制造业已形成了工业制成品和加工贸易出口为主的“世界工厂”模式,该种模式的特征为依托低廉劳动力、附加值低的粗放型增长。选取2000~2013年中国出口世界工厂模式的资源、人力、资本投入及出口、经济和环境产出指标,对全国及分省的出口世界工厂模式效率进行了数据包络分析(DEA)测度。结果发现,2000~2013年,全国及分省的出口世界工厂模式效率整体有所提高,但受金融危机影响,2008年以后效率出现了波动。非DEA有效的年份及区域,其成因主要包括资源环境、人力资本的投入冗余;加工出口、环境产出冗余。未来随着世界市场低迷、部分产业产能过剩、人口红利的逐渐消失、资源环境的压力增大,加工产品出口的世界工厂模式亟需转型。转型发展的关键举措包括增强自主创新能力,加快产业结构调整等。


    China’s manufacturing industry has been formed a export-oriented model, also called ‘world factory’, characterized by export processing industry based on the cheap labor and low added value. The article selected the index system of resources, energy, human capital, capital investment, exports, economic and environmental outputs. Export efficiencies of China and 31 provinces since 2000 to 2013 had been analyzed by data envelopment analysis measure. It was found that from 2000 to 2013, the national and provincial exports’ efficiencies had increased. However due to the financial crisis, there had been fluctuations in the overall efficiency of the manufacturing export factory after 2008. In 2009, 2010 and 2012, national export efficiencies are non-DEA effective, with only 0.866, 0.958 and 0.944 , respectively. In terms of provincial effectiveness, 22 provinces reached DEA-effective in the world-export-plant-model, while 27 provinces effective in 2010, 29 provinces effctive in 2013. In 2005, Liaoning, Jilin and other nine provinces were non-DEA effective. In 2010, the number of non-DEA effective provinces dropped to four, namely Liaoning, Hubei, Sichuan and Gansu, respectively. In 2013, the number of non-DEA effective provinces reduced to 2, Shanxi and Hubei province, respectively. The causes of non-DEA effective regions include redundancies of resources inputs, investment in human capital, exports processing, as well as environmental outputs. The model of exports of processed products in the world factory pattern should be urgently restructured in the future, as the world’s market downturn, some industry overcapacity, gradually disappearance of demographic dividend, pressure of resource and the environment increasing. Key initiatives of restructuring include enhanced capability of independent innovation, speeding up industrial restructuring, transformation from the low end assembly stage to the improved quality phase characterized by high technology content, high added value , etc.

    马丽,刘立涛
    地理科学. 2016, 36 (7): 980-988.   DOI: 10.1787/energy_bal_oecd-2015-en.
    摘要   HTML   PDF (687KB)

    通过比较英美等发达国家能源消费变化趋势,研究其出现峰值的社会经济条件,并采用长期能源替代规划系统模型(LEAP)模型对中国未来能源消费趋势及其峰值进行预测。研究发现,英美德法日加等国家的能源峰值皆是在其工业化和城市化进程基本完成、国民经济增速放缓、人均居民收入达到较高水平、整体社会经济进入平稳状态后才出现。根据中国社会经济发展趋势,随着产业结构转型和发展方式调整,中国工业能源消费峰值可能在2020~2030年期间实现,但生活和交通能源消费还将随着居民生活水平的提高而不断增长。预计中国能源峰值将在2040年左右出现,届时能源消费量将达到58×108t标准煤。为了保障如此巨大的能源需求,中国将面临较大的生态安全和国家安全风险。为此,中国必须转变传统经济发展观念,在保证国家稳定的前提下,适度降低经济增速,并尽快促进产业结构转型,提高能源开发和利用效率,同时要积极开展国际合作,保障国际油气进口的安全性。


    Since 2000, the sustained and rapid growth of Chinese economy and relative rough growth model has lead into the huge increase of energy consumption. China has become the world’s largest energy consumer. Given the huge scale of energy consumption and impact on global climate change, the peak value and its coming time become the important issues for Chinese sustainable development. Through the comparison of energy consumption trend of some developed countries, the social and economic conditions of the peak value were studied. Then, this article estimated the trend of China’s future energy consumption with LEAP model taking the social and economic elements concerned, including growth rate, industrial structure, urbanization rate, population and vehicle-motors. It found that most developed countries, such as Canada, France, Germany, Japan, United Kindom and United States, have really get their energy consumption peak value in the beginning of 21st, when they had really finished the industrialization and urbanization process, the growth rate of GDP slowed down substantially, size of energy and heavy chemical industry stabilized or decreased, and GDP per capita reached to certain level. Given Chinese industrilizaton and urbanization continued, Chinese energy consumption will continue to increase in a long period. This paper forecast that he peak value of industrial energy consumption will be achieved during 2020-2030 with the transformation of industrial structure and capacity saturation of energy-intensive industries,while the residential and transport energy consumption will continue to grow with the improvement of living standard. Only under the strict socio-economic conditions, such as implementing economic development mode transformation, promoting industrial structure conversion and upgrading, maintaining economic growth in moderate speed(5%-6%), pushing forward urbanization steadily(urbanization rate is 70% in 2035 and 75% in 2050), controling the number of motor vehiclesstrictly and promoting new energy vehicleactively, the scale of China’s energy consumption will get to its peak value in 2040 with the size of 5.8 billion tce. Also, such huge energy demands will make China face with great risks and costs in ecological, economic and national security. Therefore, this paper argues that the current academic and political views on Chinese energy consumption turning point of Chinese is not conducive to the realization of China’s economic and social development and long-term goals due to its continued industrialization and urbanization process.On the other hand, China must change its traditional economic growth mode and accelerate industrial restructuring and improve energy exploitation and utilization efficiency. Also, it should carry out international cooperation actively and protect the safety of international oil and gas imports.

    通过地市单元和主体功能区单元的定量分析,研究2005~2012年中国环境污染物排放的时空变化和空间集聚格局,提出降低污染物排放强度的对策建议。结果表明:环境污染物排放强度呈优化开发区域-重点开发区域-农产品主产区-重点生态功能区依次递减态势,各类主体功能区水环境面临的污染物胁迫程度持续加剧,且以农产品主产区和重点生态功能区最为突出,尽管优化开发区域和重点开发区域的大气污染物排放量呈现小幅下降,但仍然是大气污染物胁迫程度最高的地区。地市单元水环境受污染物胁迫态势“总体在加剧、局部有缓解”,东北、东部、中部板块的大部分区域以及西部板块的成渝、新疆中部、呼包鄂等地区呈高排放区连片分布格局;大气环境受污染物胁迫态势“总体较稳定、局部有缓解”,高排放区主要位于山西、内蒙古中西部、陕甘宁豫沿黄地带、环渤海、长三角等地区。中国环境污染排放具有显著的空间集聚效应且呈现增强趋势,其中,华北地区已经成为高污染物排放的主要集聚区,并表现出较强的路径依赖与空间锁定。


    Based on the multi-scale analysis of cities at the prefecture level and major function oriented zones (MFOZ), the process of spatial-temporal changes and spatial cluster of major pollutant emissions during 2005 to 2012 in China are analyzed in this article. The results show that: Firstly, the emission intensities of major pollutants present a decreasing trend in the order of optimized zones, prioritized zones, food stuff-security zone sand ecological safety zones,and the emission intensities in urbanized areas is significantly higher than that in restricted development areas. In 2012, the emission intensities of water pollutant in various types of MFOZ continues to strengthen compared to 2005, the rapid growth of emission intensitiesin food stuff-security zones and ecological safety zone sare more prominent.Secondly, the overall emission intensities of water pollutant is still on the rise at the national level, although the emission intensities decrease gradually in partial areas of prefecture-level cities in China. High COD emission areas distribute in the most areas of the East, Northeast and Central China, and show the pattern of continuous distribution in Chengdu-Chongqing region, Hohhot-Baotou-Ordos region of Western China. The nationwide emission intensities of atmospheric pollutantre main relatively stable, and the emission intensities in partial areas of China has alleviated. High SO2 emission areas is mainly located in Shanxi, Midwest Inner Mongolia,Shaanxi-Gansu-Ningxia-Henan region along the the Changjiang River,Bohai Rim region and the Changjiang River delta.Thirdly, the emissions of major pollutants have significant agglomeration effects which show a trend of increase since 2005, and theNorth China not only has become the high emission agglomeration, but also presented stronger path dependence and effect of spatial locking. Finally, some measures to reduce pollutants emission intensity are put forward,which should include in the transformation of the pattern of economic development, the establishment of control systemof environmental “red line” and the enrichment of environmental comprehensive treatment tools.

    摘要   HTML   PDF (800KB)

    经济发展速度一直是各国家经济发展水平的重要测度指标,但国家经济增速与国家竞争/影响力之间的关系及可能的阈值需要进行深入地研究,尤其是在中国经济增速下滑的背景下,迫切需要阐释经济增速下降是否影响国家竞争力/影响力。在评述既有研究进展的基础上,采用时空分析路径,探讨国家经济发展速度与国家竞争力/影响力的时空关系。首先,从历史的角度分析了15世纪以来世界权力中心的演变路径,考察了英国、美国等世界权力中心的国家经济增速变化,总结其发展规律,考察国家影响力与国家经济增速之间的对应关系。然后着眼于空间视角,考察目前国家经济增速与国家竞争力的空间分异,尤其是考察两者之间关系的分异关系,总结主要特征与规律。研究发现国家经济增速与国家影响力之间并非存在严格的线性关系,但国家影响力的培育与强化仍需要一定的经济增速进行支撑,而国家经济增速与国家竞争力之间呈现逆向的对应关系,经济高速增长的国家往往竞争力较低,竞争力较高的国家往往有较低的经济增速甚至负增长。


    For a long time, the economic growth ratio and the national competitiveness/influence have been the focuses for the researchers especially the official decision maker for various countries. However, the relationship between the national economic growth ratio and national competitiveness/national influence need to be suited further. Especially under the background that China’s economic growth ratio reduced gradually, it’s urgent to probe the doubt whether the decrement of economic growth ratio impair the national influence and competitiveness in China. Based on the review on the current research, we discussed the relationship between the national economic growth ratio and national competitiveness/influence from spatial and temporal dimensions. Firstly, we described the evolving path of global power center since 15th century from a historical perspective, and analyzed the changes of economic growth ratio of global power centers such as the UK and the USA to conclude the developing regularities and investigate the relationship between national economic growth ratio and national influence. Furthermore, we discussed the spatial differentiation of current national economic growth ratio and national competitiveness, especially probe the spatial differentiation of their relationship and conclude the major features and regularities. The results show there is no rigorous linear but a curvilinear adaptable relationship between national economic growth and national influence, but the foster and intensification of national influence still need the support by a higher economic growth ratio and the global power center often has lower economic growth ratio of 5%. And a converse relationship is shaped between the national economic growth ratio and national competitiveness, and generally the country with a higher economic growth ratio has a lower national competitiveness but the country with a higher competitiveness has a lower economic growth ratio even show the negative growing trend of economy. Under the background that the economic growth ratio in China has been decreasing in recent years, this research is help to clarify the worry of scholars and policy-makers and the ratio from 5% to 7% of economic growth in China doesn’t reduce the national competitiveness/influence in the world. And the result also shows that the target of 7.5% of economic growth ratio is rational for China to upgrade into a global power center.

    采用城市形态发生学研究方法,在实地调研的基础上,利用历史文献、考古调查,结合古地图、航片、遥感影像等资料,对河南商丘归德府古城的城市形态进行了复原与分析。研究结果显示,归德府古城呈圆形的外边缘带,与呈方形的内边缘带,分别修筑于不同时期,具有不同的功能,“外圆内方”的空间形态实际上是城市变化的结果,反映了文化与自然环境两方面的作用。归德府城市形态各组成部分的变化并不一致,其中外郭城的变化最大,内城的变化相对较小,内城的街道、街区格局基本与清代的格局一致。内城的城墙-城门-护城河、棋盘格式街道格局、标志性建筑物(如文庙、府学等),以及少量的呈点片状分布的古建筑和民居,构成了归德府城市形态主体,在中原地区具有典型性和唯一性,值得特别关注和保护。


    Based on the investigation on the spot, using historical records, archaeological investigation, ancient maps, aerial photographs and remote sensing images, this article has reconstructed and analyzed the urban morphology of ancient prefecture city, Guidefu (Shangqiu) in Henan, from the angle of urban historical geography. The research shows that the Guide City has a circular outer edge and a square inner edge, built in different periods and had different functions, which means that the special form of Guide City “round outside but square inside” in fact is the result of comprehensive effect of the natural environment and social environment, and the reflection of time changes, while it is not a simple product of “Feng-shui” thought. The changes of parts of the urban morphology of Guide City do not consistent with each other, the outer part of the city changed a lot while the inner city changed less, and the streets and blocks in the city are nearly the same as it was in Qing Dynasty. The urban morphology and scale of Guide City represent the general characteristics of prefecture cities in Central China of Ming and Qing Dynasties, reflecting the characteristics of local culture and geographical environment of Central China, typical and unique. The walls-gates-moat, the chessboard street pattern, landmark building, such as Confucius' temple, and ancient residence distributed in dots and patches, constitute the main morphology of the ancient Guide City, and deserve special concern and protection. In the process of using Guide City to develop local cultural industry, urban planners should have a profound understanding of urban morphological characteristics, cultural landscape and the changing process of ancient city, in order to realize the combination of protection, development, and utilization in urban planning.

    利用综合评价、耦合协调度、空间滞后模型(SLR)等模型,对2000~2010年的中国分县农村综合发展水平及2010年的分县道路交通优势度进行综合测度,解析其两者的空间耦合协同特征,并探索道路交通对农村发展的影响机制。结果表明: 2000~2010年,中国分县的农村综合发展水平的东、中、西差异格局未突破,农村综合发展水平整体提升了33.20%。东部地区的农村发展进入优化整合提升阶段,中、西部地区在政策、产业转移、城镇化、工业化等驱动下农村综合水平提升较快,乡村多维空间历经转型重构。 2010年,县域道路交通优势度呈现出典型的“点-轴”的地域结构特征,存在东、中、西部和交通枢纽中心地与外围地区之间的地域差异,其与农村发展水平耦合协同性整体较差,处于轻度失调以下状态占县(区)总数的88.25%,西部地区协调度普遍低于0.40,交通发展与农村发展协同性较好地域集中于东部沿海地域和道路交通优势极核及轴带的县(区)。道路交通等级、密度、可介入性等影响农村综合发展。道路密度对农村发展正向影响较大,国道、省道、县道沿途邻近可进入性强,对农村综合发展有积极促进作用;高速公路和铁路有景观生态学“廓道”性质,空间上起连通作用,结构的不可穿越性,封闭性影响可介入性,高速公路的出入口和火车站空间布局对农村发展影响显得尤为重要。地级市交通中心地对农村发展带动影响明显,大城市的强聚集能力易促成周边县区的农村发展“灯下黑”的地域结构特征。道路交通设施建设的等级、阶段对农村发展的传导效应及区域交通建设的超前或滞后的科学判断核心理论,将是人文经济地理学及乡村地理学亟待关注的重要领域。


    This article examined the coupling characteristics and effect mechanism for rural development and transport infrastructure. Based on socio-economic data, road traffic vector data, using the comprehensive evaluation model, spatial lag model (SLR) and coupled coordination degree model, the rural development level and transport superiority were comprehensively examined in 2000 and 2010, in order to reveal regional structural features of both. Main results for this study are as follows: 1) The regional differences of rural development have not been changed recent the last 10 years, as differences in the eastern, central and western China. The rural comprehensive development level was upgraded by 33.2%, while rural development rate has stabilized in rural areas of the eastern region. However, rural development rate was rapid promotion in the Midwest region of China during 2000 to 2010, because of policy support, industries transferring, urbanization and industrialization. 2) The point-axis spatial structure of transport superiority distribution was significant in China in 2010, which the capital of the prefecture-level city had obvious transportation advantages, and existed some transportation advantages development axis regions around core transportation central place. Regional differences were mainly between the eastern and western China, transportation core hub and the peripheral region. 3) Road density effect on rural development significantly, due to strong accessibility of national, provincial and county roads, which have a positive role in promoting rural development. However, highways and railway had a corridor property of landscape ecology. Highway and railways were “aisle”, through connection, as impenetrable property of its structure, so that region was split into two parts, and the space layout for train station and entrance was important to rural development particularly, otherwise less impact on local development across the region. Prefecture-level city traffic center had an obvious impact on rural development. Because of a strong ability to aggregate in large cities, which resulted in a special regional structure of “center developed and peripheral poverty”. Guiding the core elements radiation output to its surrounding area was extremely important for transport center cities. 4) The spatial coupling cooperative of transport superiority and rural development was low in China, account to 88.25% of the counties in China, especially in the western region, while Tibet was particularly serious, the coordination degree lower than 0.4,transportation development and rural development synergies better geographical concentration in the eastern coastal areas. Only a few counties in western better coordination, mainly synergistic whole capital, prefecture-level cities and border areas, rural development and transport infrastructure was weak. The core theoretical of traffic facilities construction level, stage and long-term effects on integrated rural development and regional economic development, as well as leading or lagging scientific judgment of regional transportation construction, which will be the important field for economic geography and rural geography studies.

    应用探索性和验证性定量分析方法,测度并探讨了2000~2012年间湖南武陵山片区农民收入多样性的时空演变特征及其对贫困的影响。研究发现,湖南武陵山片区农民收入的多样性程度不高且呈现“先降后升”的趋势,不同县市区间农民收入多样性程度差距不断缩小;多样性程度相似县市区在少数年份呈现出空间集聚而在大多数年份为随机分布;片区内娄邵片区、张家界片区农民收入多样性程度相对较高,怀化片区最低,湘西州片区则提升幅度最大,整体上高多样化县市区向娄邵片区和湘西州片区集中;局部空间格局中高-高(HH)、低-高(LH)类型有较大的空间迁移,而高-低(HL)、低-低(LL)类型在空间上分布相对稳定且大多数年份驻留在怀化片区,湘西州片区内县市区跨空间格局类型变迁最为剧烈;农民收入多样性对增加农民收入、降低贫困有着十分显著的影响。


    Applying the exploratory and confirmatory quantitative research methods, this article measured and analyzed the spatio-temporal evolution characteristics and influence on poverty of farmers’ income diversity in Wuling Mountain Area of Hunan Province during the period of 2000 to 2012. The results showed that, firstly, the diversity degree was low and followed the “U” shape trace, and the diversity gaps between different counties were narrowing gradually. Secondly, the counties which had the similar degrees of farmers’ income diversity were clustered in a few years while scattered randomly in most of other years. Thirdly, the farmers who lived in the subareas of Loushao, Zhangjiajie had more diverse sources of income than those who lived in subareas of Huaihua and Xiangxi, and the farmers who lived in Huaihua subarea had the lowest income diversity degrees and those who lived in Xiangxi subarea experienced the fastest increase of income diversity, generally, more and more counties in the subareas of Loushao and Xiangxi had high diversity of farmers’ income sources. Fourthly, during the period of 2000 to 2012, the local spatial patterns of HH(High-High) and LH (Low-High) had moved dramatically from counties to counties, while the other patterns of HL and LL were stable relatively and stayed in Huaihua subarea in most of years, and the counties which belong to Xiangxi subarea changed their local spatial patterns more frequently. Lastly, the diversity of income had obviously and significantly influence on increasing farmers’ income and reducing poverty.

    摘要   HTML   PDF (878KB)

    以宁蒙沿黄地带为案例,基于城镇用地和最小交通时间成本划分城市影响区,分区统计影响区人口,将其与城市行政区非农人口的增速差进行统计分析。结果表明:基于城镇用地和最小交通时间成本的城市影响区划分边界更接近于行政区界;考虑城镇用地后大城市影响区扩展,考虑最小交通时间成本后小城市影响区相对扩展;以东胜区-伊旗为中心的地区非农人口增速始终显著高于潜在服务人口增速,这类城市应增强对周边县的扩散作用;以大武口-惠农区为中心的地区非农人口增速始终显著低于潜在服务人口增速,这类城市应加速产业与非农人口集聚。


    Considering ignore of traditional urban influential spheres on population analysis, population analysis was made on non-agricultural and influential population growth rate difference, by introducing urban land and minimum time cost to extend current urban influential spheres research, better to instruct urban system planning. Base on minimum time cost, taking urban land area as urban source, urban influential spheres were delineated, by contrast with traditional Voronoi diagram based on point and polygon source. Then based on urban influential spheres, combined with population grid data and urban administrative non-agricultural population, non-agricultural and influential population growth rate difference was calculated and its mean and standard error analysis on non-agricultural and influential population growth rate difference were made to make a deeper exploration on effects of urban land and minimum time cost on urban influential spheres delineation. By employing Getis statistical index of non-agricultural and influential population growth rate difference, cities with significant non-agricultural and influential population growth rate difference were recognized, so special suggestion could be made for each type of city. A case study on the areas along Huanghe River in Ningxia and Inner Mongolia Autonomous Region in 1990, 2000 and 2010, showed after introducing minimum time cost and urban land, edges of urban influential spheres were more exact like urban administrative edges, compared to traditional point and polygon Voronoi diagram; taking urban land instead of urban point as urban source, larger city’s influential sphere was larger, while traffic seemed to narrow the gap between large and small city’s influential sphere which meant traffic helped to enlarge small city’s influential spheres and reduce large city’s spheres; Dongsheng and Yijinhuoluo Counties were typical of cities whose potentially served population grew slower than administrative non-agricultural population, so this type of urban needed to enhance diffusion effect on nearby counties, while as for cities like Dawukou and Huinong whose potentially served population grew faster than non-agricultural population, infrastructure construction emphasis should be placed on aggregation of industry and attracted more population from nearby counties. This work could provide an alternative technique for urban system planning.

    基于中国范围的乡村人居环境调研数据,分析了中国农村宅基地空心现象。结果表明:中国农村宅基地空心化严重,93.5%的调研村庄有空心化现象,平均空心化率达到10.2%。省域农村宅基地空心化差异明显,其中华北、华东、华中地区普遍较高; 多种因素导致农村宅基地空心化,认为是“外出务工”、“户口迁移”、“房屋年久失修”及“一户多宅” 的受访者分别占39.94%,19.51%,25.73%和14.82%。 中国农村空心化宅基地再利用潜力巨大,但再利用难度大,需要从改革城乡二元体制和乡村空间重构的角度进行空心村整治。


    As urbanization in China has increased rapidly in recent decades, large numbers of people have moved from rural areas to urban areas in China. As a result, a great number of rural residential land are abandoned or inefficiently used, which becomes a serious problem in China. Based on the data from a nationwide rural ecological landscape survey, called “thousand villages survey”, this study analyzes the status, change modes, causes and the reuse potential of hollowing of rural residential land. Major conclusions of this study are as following: 1) Village-hollowing has been a universal phenomenon in China rural areas, where 93.5% villages have this phenomenon. The average hollowing rate of rural residential land of the surveyed villages is about 10.2%, and 14.9% rural residential land is inefficiently utilized. Therefore, village-hollowing now becomes a great challenge to rural development. 2) The hollowing rate of rural residential land varies significantly across space, where villages in north central and eastern China usually have higher hollowing rates. Therefore, it is an urgent demand to formulate regionally differentiated management and reutilization solutions of rural settlement. 3) There are many reasons related to village hollowing. The survey shows that 39.94% surveyed people believe that rural labor migration is the major reason to village hollowing. 19.51% surveyed people accuse the reason to urbanization of rural people. 25.73% surveyed people think dilapidated houses lead to village hollowing and 14.82% surveyed people trend to believe “One household, multiple housing lands” cause village hollowing. 4) It is large of potential to reuse the idle and abandoned rural housing land to meet future residential land demands from newly increased rural population, although it’s difficult and costly. The survey shows that rural people have strong wills to reutilize the hollowing rural residential land. 34.22% surveyed people choose to change the hollowed rural residential land to public green space. 14.45% and 13.08% surveyed people believe that the hollowed rural residential land should be changed into cultivated land and forest land. Therefore, policy makers should pay more attentions to following three aspects, including improving regulatory and policy for rural residential land management, strengthening the village planning and promoting the construction of beautiful country, and making feasible and differentiated rural residential land reuse schemes. Regional differences of man-earth relationship should be considered in future differential recycling schemes of rural residential land use. However, the abandoned and idle rural residential land are usually scattered in rural resident areas, which make it is difficult to renovate them into farmland in large-scale. Therefore, more attention should be paid to rural settlement planning and improvement of rural living environment.

    引入调节变量,采用香港1999~2014年的季度统计数据建立一个新实证模型,利用Pearson相关性分析方法、计量经济学非平稳数据分析方法和Granger因果关系检验方法系统分析了入境旅游、经济增长和消费物价之间的关系。研究结果表明:入境旅游、经济增长和消费物价之间存在相关性和稳定的长期均衡关系;入境旅游对消费物价的带动性高于经济增长。入境旅游与消费物价、经济增长和消费物价、入境旅游和经济增长之间都存在单向Granger因果关系,入境旅游发展必然带动经济增长并影响消费物价。入境旅游对消费物价产生影响的原因主要是入境游客规模扩大和结构单一;负面影响主要表现在影响当地底层民众生活品质、损害当地旅游形象和主客感情;对策主要为拓展入境旅游类型并使旅游发展红利惠及底层民众。


    Inbound tourism development not only drives economic growth, but also significantly influences the local goods prices in the inbound tourism destination. This article tries to build a new theoretical model to explore both GDP (Gross Domestic Product) and inbound tourism’s impact on CPI (consumer price index) in the context of Hong Kong. The study collects seasonal data of inbound tourism, CPI and GDP of Hong Kong from the year 1999 to 2014. Then, this article conducts following methods to complete the analysis. Firstly, it applies SPSS software to analyze the Pearson correlation of the 3 variables; Secondly, it uses Eviews software to estimate the long-term cointegration relationship of the variables; Thirdly, it introduces Granger causality analysis and compulsory response analysis to evaluate the quantitative relationship of inbound tourism, CPI and GDP. In conclusion, the results consisted of 5 aspects. 1) Inbound tourism, GDP and CPI has correlation between each other. 2) It has a stable long-term equilibrium relationship between inbound tourism, GDP and CPI. Meanwhile, the impact of inbound tourism on CPI is higher than the impact of GDP. 3) The unidirectional Granger causality relationship exists under inbound tourism to CPI, GDP to CPI, and inbound tourism to GDP. 4) Compulsory response of CPI to CPI and inbound tourism is sensitive than GDP, while the compulsory response of CPI to GDP has showed more hysteresis effect. 5) The reasons why inbound tourism has a significant impact on the consumer prices is that the inbound tourists scale has become larger and larger from 1999 to 2014, and the inbound market of Hong Kong has been occupied mostly by mainland Chinese tourists in the recently years. The negative impacts are that some local people consider their life quality to be affected by tourism. Moreover, the tourism image of Hong Kong has also been damaged because some protests had violent behaviors toward mainland tourists. Besides, the mutual trust between tourists and residents in Hong Kong has been ruined. Finally, the article suggested some solution for the problem, for example, the government should develop more tourism attraction to meet tourists’ different tourism demand, encouraging more local people to join in the tourism development of Hong Kong and make sure the residents to achieve actual benefits from inbound tourism prosperity.

    以社会角色与角色冲突的相关理论为指导,以云南丽江白沙村当地纳西族居民家的微观空间为研究对象,对当地居民与游客在互动过程中的角色冲突质性进行了研究。研究发现,当地少数民族居民与汉族游客在家空间的互动过程中,双方各自存在角色内冲突的现象,同时彼此之间也存在两种角色间冲突现象。互动双方在处理这些角色冲突的过程中,既反映出当地居民对经济利益的诉求,也反映出当地居民与游客在家空间中的地位与权力关系。


    As the core of ethnic tourism, the cultural interaction between local residents and tourists in ethnic tourism has been paid little attention in Chinese academic research. And the previous studies on China's ethnic communication did not involve the new ethnic exchanges promoted by ethnic tourism under the background of mass tourism. Therefore, to study the role conflicts presented in the process of cultural interaction between locals and tourists not only can help to deepen ethnic tourism research, but also can extend the field of ethnic communication studies. This article, by referring to the theory of role and role conflict from the symbolic interactionism, takes three locals’ households in Baisha Village, Lijiang, China as the micro research sites to conduct a qualitative research on role conflicts between local minority residents and Han tourists at individual level. Its findings show that multiple role conflict phenomena often take place in the interactive processes between the locals and Han tourists. While interacting with tourists, the local residents, on the one hand, intend to get economic interests from tourists by their role playing of “businessman”, and on the other hand, they have to emphasize their other two roles which are the “host” and “minority”. Specifically, the locals try to treat the tourists warmly with their role of “host” in their home space, while to protect their heritage and culture with the role of “minority”. As a result, they can maintain the advantages in the competitive market through performing their own authentic culture. Tourists also involve the intrarole conflicts between the role of “guest” and “customer”. Meanwhile, there are two interrole conflicts between the local residents and tourists, which are the interrole conflict between the tourist’s “customer” role and the local resident’s “host” role, as well as the interrole conflict between the local resident’s “businessman” role and tourist’s “guest” role. These phenomena reflect not only the locals’ pursuit of economic interests, but also the status and power relationships between locals and tourists while interacting with each other. Besides, in terms of theoretical contribution, this study not only enriches the host-guest interaction theory in tourism anthropology by examining the influence of micro space on role interactive process, but also make up for the deficiency of human geography in micro space research and tourism sociology in the aspect of space-power research.

    利用数据包络分析(DEA)方法对吉林省2003~2013年经济效率差异和空间格局演变进行了深入研究。研究结果显示:吉林省经济发展总体效率相对较高,纯技术效率值较为稳定,规模效率值波动上升,处于规模收益持续递增阶段,规模效率始终是影响综合效率的主要原因;中部地区的综合效率水平高于东部和西部;在分解效率方面,与综合效率大致相同,中部地区的纯技术效率和规模效率均高于东部和西部;受区域经济发展不平衡影响,不同城市投入的资源水平存在差异,综合效率,纯技术效率和规模效率均呈现出由中部地区向东、西部扩张的空间格局。不同城市类型、城市规模对吉林省经济效率演变具有十分重要的影响;区域经济政策、市场经济、工业基础和产业集聚、科技水平等驱动力共同作用于吉林省经济效率空间格局的演化。


    As a typical example of old industrial bases and major grain producing areas, Jilin Province is playing an important role in economic development and food security in China. However, because of relying on extensive mode of growth with high pollution and high energy consumption in a long period, it was paid more attention to output of production and overlooking the promotion of economic efficiency in Jilin Province. To improve the economic efficiency and to make the industrial structure realize the transformation and upgrade are urgent. It is an emergency to improve economic efficiency under the circumstances of economic "new normal". An analysis of economic efficiency difference and spatial pattern evolution in Jilin Province from 2003-2012 is carried by means of DEA. The results show that the total efficiency of economic development is relatively high in Jilin Province, the technical efficiency relatively is stable, the scale efficiency wavelike rises, and in the stage of progressive increase of scale return, the overall efficiency is always influenced by scale efficiency. The overall efficiency level in the central Jilin is higher than eastern and western Jilin. The overall efficiency presents differences among eastern, central and western Jilin, and the difference is mainly the big gap between central and western Jilin. The same as overall efficiency, the technical efficiency and scale efficiency of central Jilin is higher than eastern and western Jilin. The devoted resources level in different cities exist differences because of the unbalanced economic development, the overall efficiency, technical efficiency and scale efficiency. The city size has great influence on the economic efficiency evolution in Jilin Province. The result of quantitative analysis shows that secondary industry, the tertiary industry, transportation, reform of state-owned enterprises and high educators play an important role in the promotion of economic efficiency in Jilin Province; Regional economic policy, market economy, industry base and industrial agglomeration, level of science and technology impact on the spatial pattern evolution of economic efficiency in Jilin Province. The difference of economic efficiency is the foundation to make the regional division come to realize.

    以Web of science核心数据库中1991~2015年间收录主题为“livelihood vulnerability”的文献为基础,应用可视化分析软件CiteSpace ,采取关键词共现分析、文献共被引分析、突现词分析等方法对生计脆弱性研究现状进行可视化分析。研究发现: 生计脆弱性研究文献呈现逐年上升趋势,主要分布在生态、环境和管理等学科领域;美、英、澳、加、德5国及东英格兰大学、哥本哈根大学、麦吉尔大学、利兹大学、萨塞克斯大学等研究机构具有较强的研究实力。 Ellis F、Smit B、Adger W N、Kelly P M、Davies S和Turner B L等学者及其代表作是生计脆弱性研究的知识基础。 饥荒、社会生态系统、生计策略、贫困、减贫等是生计脆弱性的研究热点与前沿领域。


    Livelihood vulnerability has become a hotspot research of global environment change and it is also one of the important research paradigms of sustainability science. Firstly, according to the web of science database in 1991-2015 which included the literature of livelihood vulnerability, the article analyzed the livelihood vulnerability’s distribution status, in terms of time, area, organization etc,by using statistics and visualization. The results show that the quantity of the international livelihood vulnerability research documents are on arising trend, mostly specializing in the subject of ecology, environment, resources and management or other related topics. Five countries (i.e. the United States, the United Kingdom, Australia, Canada, and Germany) and research institutions of University of East Anglia, University of Copenhagen, McGill University, University of Leeds, and University of Sussex show great research strengths of livelihood vulnerability. Secondly, applying the information visualization software CiteSpace , this article drew the document co-citation network of livelihood vulnerability, and discussed the knowledge base and core authors. Scholars like Ellis F, Smit B, Adger W N, Kelly P M, Davies Sand Turner B L etc. and their representative works laid a solid foundation in the establishment of the theoretical elementary knowledge and other related researches. Finally, based on the keywords and burst phrases analysis of co-word and word frequency, this article drew the evolution network of livelihood vulnerability research hotspot, and explored the frontier proposition research of famine, political economics, social-ecological system, livelihood strategies, poverty reduction and so on. Because of researcher's different situation and various research motives, the research hotspots of livelihood vulnerability are mainly concentrated in the following four categories:1) Residents in ecologically fragile areas are currently being much more dependent on the natural environment and natural resources than before, climate change and agriculture research has therefore become the hotspot in livelihood vulnerability research. 2) In order to analyze food security vulnerability of different groups and help them improve their ability to deal with those problems, WFP launched the vulnerability analysis and mapping project. The way to improve adaptability, resilience and level of scientific management is always the main target in livelihood vulnerability research. 3) Poverty and risk have being two of the core issues in research course, under developed areas are often poor in resource of health care, and they also exists instability in social and political environment, leading to birth risks faced by the local population greatly increased. 4) Continuous conflict from dry weather and regional impact of fragile conditions both pose a great challenge to the well-being of local dwellings. And Africa continues to be the key areas of livelihood vulnerability research.

    摘要   HTML   PDF (6492KB)

    利用Arc-GIS空间分析软件对各类型污染进行空间识别和分布模拟,探究长株潭城市群污染空间分布特征。结果显示: 该区大气环境污染以扬尘和煤烟型为主,主要污染物为可吸入颗粒物和二氧化硫,重点污染区域在长沙、株洲、湘潭三市主城区,呈点状分布;该区水域整体水质基本达标,水体环境污染以氨氮和各类重金属为主,且有明显的季节变化规律; 土壤污染覆盖范围较广,以株洲市的石峰区为代表,以镉污染最为严重,主要原因为重化工业排污累积。总之,株洲污染最严重,湘潭和长沙次之。污染空间的形成与长株潭城市群的地形地势及三类污染元素之间的转化有较大关联。


    By ArcGIS spatial analysis software, this study aimed to carry out the space recognition and distribution simulation for each pollution type (i.e., air pollution, water pollution, soil pollution) and comprehensive pollution within Changsha-Zhuzhou-Xiangtan Urban Agglomeration, and discussed their characteristics. It can be concluded that: 1) The atmospheric environment pollution is given priority to fugitive dust and coal smoke with the main pollutants as PM10 and SO2, and the key pollution areas are the central downtowns of Changsha, Zhuzhou and Xiangtan City, exhibiting dots distribution; 2) The whole water quality basically reaches the standard, and water environment pollution mainly resulted from ammonia, nitrogen and various heavy metals with the significant seasonal variation; 3) Soil pollution is rather serious with a wide coverage. Taking Shifeng District of Zhuzhou City as a representative, Cadmium pollution is the most serious one, which is caused by the accumulation of heavy chemical industry pollution; 4) Overall, Zhuzhou is the most polluted, which is followed by Xiangtan and Changsha. The formation of pollution space is greatly related with the terrain and topography of Changsha-Zhuzhou-Xiangtan Urban Agglomeration, and influenced by the transformation among these three kinds of pollution elements.

    通过对澧阳平原野外调查,多剖面地层对比分析及岩板垱(YBD)剖面样品的粒度、地球化学元素分析和年代测定,揭示该区晚更新世晚期至全新世早中期环境演变,并探讨其对人类活动的影响。研究结果表明,30~6 ka B.P.间,澧阳平原由冲沟发育的黄土台地向河湖发育的平原丘岗地貌过渡;气候环境经历了弱暖湿-气候变差-凉湿-波动回暖-暖湿的变化;更新世末至全新世早期稻作农业的出现与该区的环境条件和文化基础密切相关;环境演变也推动了古人类活动范围和聚落特征的变化。


    Based on detailed field surveys, comparison of strata of typical profiles and experimental analysis (including grain size, geochemical analysis and optically stimulated luminescence (OSL) dating) of samples collected at the Yanbangdang (YBD) site, we explored the environmental evolution from Late Pleistocene to Middle Holocene and its impact on human activities, especially on the origin and development of rice agriculture in Liyang Plain. The results showed that the climate of the Liyang Pain during 30-6 ka B.P. experienced five stages: relatively warm and humid in the Late Pleistocene, cool and humid during the Last Glacial Maximum (LGM), fluctuated warming in the terminal Pleistocene and Early Holocene, and warm and humid during the Middle Holocene. In the Late Pleistocene, landforms of the Liyang Plain were characterized by tablelands drained by rivers and gullies in the Late Pleistocene, with topographic relief much higher than present. As climatic amelioration during the terminal Pleistocene and Early Holocene, continuous filling and siltation occurred in Liyang Plain and large areas of wetland was formed. Landscapes of the Liyang Plain at this time were mainly plains and hillocks with dense rivers and lakes and the topographic relief was gradually reduced. During the Middle Holocene, landforms of Liyang Plain were mainly alluvial and lacustrine plains with scattered mounds and hillocks. Under the relatively suitable environmental condition of the Late Pleistocene, the Late Paleolithic human activities existed continuously in Liyang Plain especially in the surrounding mountain and hill areas. Climate cooling during the LGM did not cause severe damages to regional ecosystem and ancient people also took steps to temperature drop, which allowed continued development of transitional culture from the Paleolithic to the Neolithic in Liyang Plain. Liyang Plain had favorable environmental conditions (e.g., abundant moisture, proper temperature, suitable landforms and rich fertile soil) and solid cultural foundation (continuous human activities and a long history of rice exploitation) in Early Holocene, which contributed to the origin and development of rice agriculture in this area. The warm and humid of the Middle Holocene climate promoted rice agriculture to a new level and the Neolithic culture expanded to the lower flat plain areas.

    以福州市建成区为例,基于Landsat遥感影像对水体类型进行分类,并提取出1989、1996、2006和2014年的地表水体信息,然后与不透水面、植被和地表温度信息结合,运用回归模型定量分析了1989~2014年间福州城市地表水体的时空变化及其对城市热环境的影响。结果表明: 1989~2014年间,福州建成区各类地表水体均呈不断减少趋势,25 a间水体总面积减少了1 490.67 hm2,其中有70.0%转变成不透水面; 1989~2014年减少的1 490.67 hm2水体对福州建成区温度上升的贡献达1.03℃,而在水体减少的具体区域,其升温效应可达3.6℃。


    Shrinkage of urban surface water bodies has caused a series of problems, such as degeneration of urban ecological quality and the intensification of urban heat island phenomenon, which severely affect human living quality. Fuzhou City, as the capital city of Fujian Province in southeastern China, has witnessed a rapid urban expansion process during the last three decades. The rapid urban growth of Fuzhou City has led to the shrinkage of urban surface water bodies and induced a series of urban environmental problems. To reveal the relationship between the change of surface water area and urban heat environment, remote sensing technique was employed using multi-temporal Landsat TM/OLI/TIRS images of 1989, 1996, 2006 and 2014. The use of the modified normalized different water index (MNDWI) has successfully extracted the information of the city’s surface water bodies from the images. The selected thresholds for the extraction of water bodies of the four study years (1989, 1996, 2006, 2014) were 0.1, 0.1, -0.05 and -0.05, respectively. Because the water area of both Min River and Wulong River, which flow through the study area, were basically unchanged in the four-study years, they were masked out in this study. The assessment of the accuracy shows that the overall accuracies of the water extraction of the four years are all greater than 90.0%, which met accuracy requirements. The extracted urban surface water bodies were classified into three types: river, lake and pond by using shape index. Furthermore, the impervious surfaces and vegetation were extracted by two remote sensing indices, i.e., normalized difference impervious surface index (NDISI), and normalized difference vegetation index (NDVI), respectively. While, the land surface temperature (LST) was retrieved using the single channel algorithm (SC). Combined with LST, impervious surfaces, and vegetation information, the extracted water images were used to analyze the spatiotemporal variation of Fuzhou’s surface water in 1989-2014. Regression analysis was carried out to investigate the quantitative relationship between water and LST. The result shows that all three types of surface waters in Fuzhou urban built-up area have decreased substantially in 1989-2014. Water area decreased by 1 490.67 hm2 in 25 years and 70% of the decreased waters converted into impervious surfaces. Of the reduced water, river area decreased by 1 490.67 hm2, pond area decreased by 951.21 hm2, and lake area decreased by 408.15 hm2 during the period. The calculation shows that difference in LST between water and impervious surface is 11.12℃, while the difference between water and vegetation was 4.38℃. A significant negative correlation between the proportion of urban surface water and LST has been detected. According to the regression model, the decrease of surface waters in Fuzhou built-up area in 1989-2014 has contributed to the temperature rise by 1.03℃. However, in the local area where water area has reduced substantially, the warming effect is more obvious. Taking Puxia wetland as an example, the decrease of the surface water area of the wetland in 1989-2014 has contributed to the temperature rise by 3.6℃. Obviously, the reduction of urban surface waters has significantly intensified the urban heat island phenomenon of the city.

    于2014年春、夏和秋季对长白山玄武岩台地原始针阔混交林、次生针阔混交林、次生落叶阔叶林及耕地土壤动物进行研究。结果表明:大型土壤动物的多样性,春季次生针阔混交林为最高,夏季和秋季原始针阔混交林为最高,耕地在3个季节均为最低;中小型土壤动物的多样性,春、秋两季原始针阔混交林为最高,夏季次生针阔混交林为最高,耕地在3个季节仍为最低。根据一维方差分析可知春、夏、秋3个季节原始针阔混交林、次生针阔混交林和次生落叶阔叶林土壤动物类群和平均密度均显著高于耕地(p<0.05);而各生境土壤动物的类群和平均密度季节变化差异不显著(p>0.05)。各生境土壤动物的多样性呈现出随土层深度的增加而降低的趋势。土壤温度、速效P、有机质和土壤湿度的变化是影响长白山玄武岩台地土壤动物多样性地理分布的主要因子。


    Soil fauna play an important role in terrestrial ecosystems. They are closely connected with the above and under ground ecosystems. The effect of basalt platform on the diversity and ecological geographic distribution of the below ground soil fauna is unknown. In the present study, an investigation of diversity and ecological geographic distribution of the below ground soil fauna was conducted in the basalt platform of the Changbai Mountains with four habitats types (original conifer and broad-leaved mixed forest, secondary conifer and broad-leaved mixed forest, secondary deciduous broadleaved forest and arable land). The plots (5 m×5 m) were established using permanent signs in each of the arable land. The plots (20 m×20 m) were established using permanent signs in each of the other three habitats types. Within each plot, five subplots were selected randomly, and 25 cm×25 cm and 10 cm×10 cm areas were collected from the litter layer, 0-10 cm, 10-20 cm and 20-30 cm soil layers in each subplot during spring, summer, and autumn 2014. Soil macrofauna and soil meso-microfauna were extracted from each of the soil samples using hand collection methods and Tullgren funnel extractor, respectively. The effects of habitat types, seasonal variations and soil layers on the abundance, richness of soil fauna were analyzed using one-way ANOVA and multivariate analysis. Indexes of diversity were calculated to describe the characteristics of the diversity of soil fauna. The influence of soil environmental factors on soil faunal diversity was examined using redundancy analysis (RDA). The results showed that the dominant groups were Isotomidae, Oribatida and Hypogastruridae. The common groups included Gamasida, Actinedida, Pseudachorutidae, Diptera larva, Sminthuridae and Tomoceridae. In spring, the secondary conifer and broad-leaved mixed forest had the highest diversity of soil macrofauna among the four habitats. For soil macrofauna, in summer and autumn, original conifer and broad-leaved mixed forest had the highest diversity among the four habitats. However, in spring, summer, and autumn, the arable land had the lowest diversity among the four habitats. For soil meso-microfauna, in spring and autumn, original conifer and broad-leaved mixed forest had the highest diversity among the four habitats. In summer, secondary conifer and broad-leaved mixed forest had the highest diversity among the four habitats. However, in spring, summer, and autumn, the arable land had the lowest diversity of soil meso-microfauna among the four habitats. The one-way ANOVA showed that a significantly lower abundance and richness of soil fauna was evident in the arable land when compared to all other habitats in spring, summer, autumn (P < 0.05). However, abundance and richness of soil fauna did not respond significantly to variations in seasons (P > 0.05). From the vertical distribution, the diversity of soil fauna in each habitat was shown that it was decreased with the increasing soil depth. Redundancy analysis (RDA) showed that diversity and ecological geographic distribution of the below ground soil fauna was correlated significantly with soil temperature, available P, organic matter, soil moisture.

    基于中国气象科学数据共享服务网提供的1979~2012年夏季6~8月降水实测数据(CMD)和3种不同来源的再分析降水数据,研究和比较副高特征指数与洞庭湖流域夏季降水的关系及空间差异。结果表明: 6、7月副热带高压(副高)脊线位置偏北,洞庭湖流域大部分区域降水偏多,8月偏少;6、7月北界位置偏北使流域东南降水偏少、西北降水偏多,8月大部分地区降水偏多;6~8月西伸脊点位置东移使降水偏多范围自东向西增大;6月份副高强度增强使东部和南部降水偏多、西部和北部降水偏少,7和8月大部分地区降水减少。再分析降水数据大体上能反映出7月份脊线指数、6和7月北界指数、6~8月西伸脊点指数和副高强度指数对相应月份CMD降水的影响。 副高特征指数对CMD降水的拟合能力存在区域差异。


    This study was to compare the relationship between western pacific subtropical High(WPSH) and summer precipitation from different precipitation data in Dongting Lake Basin (107°13'-114°18'E,24°35′-30°27′N). The data included observation precipitation of 27 meteorological stations from China meteorological data sharing service system (CMD), and the reanalysis precipitation data such as European centre for medium-range weather forecasts ERA-Interim reanalyse data (ERA-Interim), climatic research unit time-series version 3.21 of high resolution gridded data of month-by-month variation in climate (CRU-TS 3.21), and the version 2 global precipitation climatology project monthly precipitation analysis (GPCP V2.2). Employed multivariate regression analysis,standard multiple regression equations were set up by using five indices of WPSH and monthly precipitation data from June to August. The distribution and change of the partial regression coefficients of five subtropical high indices were discussed, and the composite influence of subtropical high indices on the precipitation was analyzed by multiple correlation coefficient of every equation. The results indicated that the CMD precipitation in most area of Dongting Lake Basin increased but decreased in August by the position of ridge line moving northward in June and July. The position variation of ridge line in July and August made significant changes in precipitation. For precipitation from ERA-Interim data in June, all reanalysis data in July, CRU data in August, the ridge indice performed the same influence as it did on CMD. With the position of northern boundary moving northward, the precipitation in June and July increased in northwest but decreased in sourtheast, and increased in August in most area of Dongting Lake Basin. The position variation of northern boundary in July and August effected significantly. The influences of northern boundary indice on three reanalysis precipitation data in June and July were similar to that of CMD, but different in July. When the west-extending ridge point position moved easterward, the rainfall area enlarged from east to west, but the precipitation changes in June only was effected significantly by its variation. The influences of west-extending ridge point indice on three reanalysis precipitation data were generally coincident with that of CMD except GPCP in August. There were more precipitation in east and south, but less in west and north because of strengthening Intensity of WPSH in June, which made less precipitation in July and August to most area of Dongting Lake Basin. From June to August, intensity indice did not effect significantly. All three reanalysis data could reflect the influence what the intensity indice did on CMD. According to the methods used in this study, the area indice and the intensity indice showed the reverse effect on precipitation.The fitting ability of five indices of WPSH exhibited differently in time and space for CMD precipitation data. Based on time perspective, the fitting ability in June was better than July and August. Spatially, it showed good fitting ability in west and east of Dongting Lake Basin in June, so did in south and north in July and August. For ERA-Interim, CRU and GPCP data, the fitting ability of five indicators of WPSH in some areas agreed with what CMD showed in June and July. But in August, it had a good consistance with that of CMD in the whole basin for ERA-Interim.
