    国家出台大批国家级区域发展战略和各地制定相应的区域规划,给中国的人文-经济地理学带来了极好的发展机遇,其中,思考中国的区域制度是一个重要的理论命题。阐述了现行区域规划在内容体系上的“短板”,指出了“短板”的存在有中国区域制度的原因。通过“区域”的“政府”性质分析了区域规划中存在“短板”的必然性,进而讨论了中国“产权区域”制度下“区域”的“私人物品”特征、区域的竞争性和排他性,由此产生的区域与中央政府的博弈关系和区域外部性等问题。人文-经济地理学必须在区域制度方面深化对中国的区域规划、区域发展和区域关系等问题的认识。


    A large number of state-level regional development strategies issued by the central government and corresponding regional planning formulated by the local governments, for China′s humanity-economic geography, has brought great opportunities for development. Why economic region in China is different from any other countries, why to develop in a high speed become a common problem among China′s economic regions, why China′s economic regions still did it in their own way although has been strongly condemned, if this economic regional system had something to do for China′s rapid development of economy, all the questions mentioned above are worth thinking for humanity-economic geographers. Dozens of regional strategies issued by the central government and corresponding regional planning have been established in recent years, all these strategies and planning are used by government as a means of macroeconomic regulation and control, and also used by the scholars in the field of region and urban planning as a means of service for practice. This paper think that government establishing regional strategies and planning which don′t follow the rules of market economy are always failure in many case, meanwhile, it′s side effects are very obvious, such as extensive development. excessive expansion of urban construction land, resources excessive consumption, coordinated development among regions. The content system of current regional planning has a "short board" for the reason of region system. The economic region in China is a kind of "property region" in nature, the government is the subject and representative of the region, under these condition, "property region" to "regional government" and the central government is in "personal items" characteristics. As long as it is a "personal items", the property region will inevitably be a selfish, competitive and exclusive, and conflict with the state's interests of public goods. Therefore, China's economic region must be competitive and exclusive. It is due to the competition among economic regions to make China′s regional system a institutional power to promote economic and social development. This paper also explains another three characteristics of China′s regional system. First, the market allocation of resources will always follow their own rules, when the governments intend to violate the rules of the market, the market is often pay no response, such as the irrational industrial development and population size prediction in the regional planning. Second, when the central government is no longer the main body of the resource allocation, the existence of game relation between local government and the central government makes the local government not to completely obey all the arrangement of the central government, especially the arrangement do not conform to the interests of the local government demands. The third, regional externalities is an objective phenomenon, regional development will bring to other regions positive or negative influence and will not assume responsibility or gains. China′s regional system has play an important role for its development, and is still in need of improvement, so, this field should be the direction of the fundamental theory research for humanity-economic geography.

    地域资源禀赋差异及经济社会发展阶段性决定了耕地资源开发强度理应存在结构演化的阶段性。基于粮食生产角度提出了涵盖开发广度、开发深度、开发频度的耕地资源开发强度评价方法。据此,通过评价分析全国及区域开发强度演化特征,论证了耕地资源开发强度阶段性结构演化假设。结果表明:耕地资源开发强度评价能准确判断耕地资源开发状态;中国耕地资源开发已基本完成以提高开发广度为主要特点的外延式开发历程,当前正值以提高开发深度为主要特点,同时面临开发频度降低问题的内涵式开发阶段;2004年,中国耕地资源开发强度为25.064%,区域开发强度及其结构演化差异显著。最后,在明确耕地资源管理政策转型基本导向的基础上,探讨了区域差别化的开发强度管控政策。


    Regional differences of resource endowment and economic and social development decide the phase characteristic of the evolving structure of the exploitative intensity of cultivated land resources (EICLR). From the standpoint of grain production, this article put forward an evaluation method which involves explorative breadth, exploitative depth and exploitative frequentness and the assumption of the phase characteristic of the evolving structure. The empirical results are proved well at the country and the provincial scales. Evaluation of the EICLR depicts successfully the phase characteristic of the evolving structure and estimate accurately the regional exploration status of cultivated land resources. Thus, it could provide scientific evidence for cultivated land resources management. Overall, the phase of extension type of cultivated land resources exploration which has the main features of raising explorative breadth has been completed in China. With the rapid development of industrialization and urbanization, cultivated land resources exploration has entered the era of intension type which has the main features of raising explorative depth. Noteworthy is that the decline of exploitative frequentness is also the serious issue during this era. Value of the EICLR at the country level is 25.064% in 2004. In the meanwhile, significant differences of the EICLR and its structural evolution are shown across agricultural zones and the 31 provinces. Finally, regional differentiated regulation policies of the EICLR are proposed under the direction of cultivated land resources management transition.

    最优选址在社会经济活动中非常重要。传统的网络聚类分析以空间两点之间的直线度量距离,而不是以空间最短网络路径作为聚类条件,无法找到复杂网络的最优选址中心。基于最短路径的复杂网络聚类模型,探索复杂道路网络中的最优选址。模型通过迭代法获取近似最优解,二分邻域分割法逼近最优解分布区,应用邻域下降法达到最优选址点。实验结果表明:本模型与穷举-Dijkstra算法相比,计算精度相当,计算速度提高了约23倍以上。模型以复杂网络聚类为基础推导,为复杂网络选址、聚类提供了一种新的理论与方法。


    The best location for site selection is very important for social and economical systems. Traditional clustering analysis cannot reach the optimal location allocation center based on the Euclidian, Manhattan, Chebyshev, Fu or Tanimoto distance,which does not depend on the shortest path distance as the clustering condition. Complex network clustering model based on the shortest path is proposed to explore site selection in this paper. The approximate optimal results are obtained using the iterative technology. The searching range of optimal site allocation is approached by half dividing the neighborhood. And the best location is captured applying the descend strategy. Experiments indicate that the proposed model can improve the calculating speed by at least 23 times with the same precision to approach the optimal resolution compared to the greedy Dijkstra algorithm. This model is inferred from the complex network clustering. It provides new theory and method to cluster complex network and locate sitting facilities.

    The urbanization and industrialization needs a large number of land resources to support, so there is much land from agricultural use into non-agricultural purposes, result of which is a large quantity loss of cultivated land and too much construction land. New construction land space is limited, so it is have to reuse the inefficiency stock of construction land, namely rural residential land to support the urbanization process. The advancement of rural residential land consolidation not only increases the quantity of cultivated land, ensures the land demand of city and town growth, but also is an important way to speed-up the urban and rural co-ordination development and the new rural construction in China. The study of potential estimation and layout optimization of rural residential land consolidation is the important basis and key technology of residential land consolidation plan, then this paper is to research the two parts. With per capita residential land in present minus per capita standard stipulated by the State, the paper estimated the theoretical potential of rural residential land consolidation in Jiangdu City, considering restraint correction coefficient of the natural, economic and social constraints which was used to amend the theoretical potential to reality potential. Getting rid of reality potential from present rural residential land was the retained residential land; the next step was to make this part of land reallocation in space. So the paper optimized the residential land layout from location, nature and other aspects, using multi-factor comprehensive evaluation method to evaluate the fitness of settlement construction of grid cells in ARCGIS 9.3, Which weights was determined by Delphi method, and then making the highest fitness grid cell into residential land until the total chosen grid areas was equal to the result of status rural residential land minus reality potential. It was found that the theoretical potential of residential land consolidation of Jiangdu City in 2008 was 6 128 ha, while the reality potential amended by restraint factors was 2 013 ha, and more than half of which was in Xiannv town, which demonstrated Xiannv was centre of gravity of residential land consolidation in Jiangdu future. The distribution of residential land became concentrated after layout optimization, mainly concentrated around the towns or in convenient traffic areas, and had changed the current scattered distribution and reduced the number of plaques so as to make a significant increase in degree of concentration.

    山地森林带界线对地形差异和气候变化敏感,是地学、生态学研究的重要内容。利用13个气候指标进行主成分分析,提取出中国31个自然地带的气候指数,包括夏季温度变异指数(STVI)、冬季温度变异指数(WTVI)和干旱指数(DI),3个气候指数符合地带性分布规律,STVI从南向北递减,WTVI以东部地区和南疆部分地区最高,DI则从东南向西北递增。基于文献发表的中国28个典型山体的森林带界线数据,将其与山体基面高度、山体相对高度和地带性气候指数进行多元回归分析。结果显示,山体基面高度对森林带下线南北坡差异贡献最大(39.67%),山体相对高度对森林带上线南北坡差异贡献最大(39.34%)。3个地带性气候指数的累积贡献对森林带上线南北差异、下线南北差异和带宽南北差异的影响差别不大,在51.4%~55.9%之间,其中STVI贡献最大,其次是WTVI和DI。通过定量揭示地形和气候要素对山地森林带界线差异的贡献,可以为区域或全球尺度的山地森林带界线评价和模拟提供参考。


    The division of vegetation zones is an old and highly emphasized topic in both botany and geography. High mountains are characterized by different vegetation types at different elevations. Altitudinal vegetation belts are bounded by relatively narrow boundaries. Investigation and identification of altitudinal vegetation belts is significant in ecological and geographical studies due to extremely complex environment and diverse vegetation types in mountains. Altitudinal forest belts (AFBs) are significantly impacted by topographic and climatic factors. The climatic data used in this study were obtained from Chinese Ecosystem Research Network (CERN) between 1960 and 2000. After analyzing the significance of the 13 climatic factors in 31 base belts, we obtained three dominant principal components (PCs) designated as temperature variation index in winter (WTVI), temperature variation index in summer (STVI), and drought index (DI). WTVI decreased from South to North China, whereas STVI was high in South China and Tibetan Plateau. DI increased from the southwest to the northwest of China. Next, 28 AFB data were collected from published references. Multivariate regression analysis was used to quantify the relationship between AFB characteristics and topographic and climatic PCs. Results show that the base elevation of a mountain has the significant contribution to lower limits of AFBs (39.67%), whereas the relative elevation of a mountain has the significant contribution to upper limits of AFBs (39.34%). The climatic factors have similar contributions to variations in upper limits, lower limits, and width of AFBs. Among the three climatic PCs, STVI has the most contribution to variations of AFBs, followed by WTVI and DI. This paper quantifies the relative contributions of topographic and climatic factors to variations in AFBs at regional scales, and could potentially be used to evaluate and model the AFB distributions in other mountainous regions at regional or global scales.

    Groundwater function assessment is the extension and expansion of groundwater resources evaluation. According to the concrete conditions in the study area and considering the information availability, the indicator system for groundwater function assessment was established from the points of groundwater function provision and groundwater function demand. The AHP(analytic hierarchy process) method and space superposition analysis technique of GIS were adopted to assess the groundwater function in the lower reach of the Liaohe River Plain, and function index of resources function, ecology function and geo-environmental function were obtained. The results show that the regions with the best and better resources function mainly locate in Sujiatun, Xinmin-Liaozhong plain, the Liaohe River and the Hunhe River Alluvial fan. The proportions of the study area in each resources function category are: 0.95% of strong function, 23.64% of moderately strong function, 25.62% of moderate function; 27.38% of moderately weak function, and 22.41% of weak function.The regions with the best and better ecology function mainly locate in the Alluvial fans of the Taizihe River, the big and small Linghe, the south coastal region and the center plain. The proportions of the study area in each ecology function category are: 5.62% of strong function, 17.95% of moderately strong function, 24.73% of moderate function, 23.52% of moderately weak function, and 28.18% of weak function.The regions with the best and better geo-environmental function mainly locate in the Hunhe river and the Taizihe river, the alluvial fans of the big Linghe and the small Linghe, and the line from Panshan to Yingkou. The proportions of the study area in each geo-environmental function category are: 4.93% of strong function, 19.42% of moderately strong function, 24.15% of moderate function, 27.02% of moderately weak function, and 24.48% of weak function.The regions with the strongest and strong comprehensive function mainly locate in the Sujiatun, Liaozhong and Taizihe alluvial fan. The proportions of the study area in each function category are: 2.62% of strong function, 21.54% of moderately strong function, 22.87% of moderate function, 25.49% of moderately weak function and 27.48% of weak function.A comparison analysis between the groundwater function map and the public information about groundwater assessment, environment hydrogeological problems, groundwater vulnerability and groundwater utilization in study area provided by the Department of Land and Resources of Liaoning Province was carried out, which shows that the assessment results of groundwater is well fitted with the actual situation. This indicates that the assessment results are valid, and the indictor system constructed in this paper can be successfully applied to assess groundwater function.The research results have the certain reference significance for the maintenance of groundwater function and the scientific management of groundwater resources in the lower reach Liaohe River Plain.

    基于GIMMS NDVI数据、GIS技术,综合运用趋势线分析、统计分析和空间自相关分析方法,对1982~2006年大兴安岭整体及各生态地理区域植被特征进行检测分析。结果表明:从整体来看,大兴安岭植被NDVI增加趋势明显,NDVI呈现上升趋势的区域约占研究区总面积的80%;NDVI对气象因子变化敏感,尤其是对气温的敏感程度高于降水;并且在全局范围内呈现正的自相关,不同生态地理区内的全局自相关系数自北向南逐渐升高。各生态地理区NDVI变化趋势差异明显,植被退化的区域集中在大兴安岭北段和中段,在局部自相关分析中NDVI仍然呈现高-高聚集趋势;北段西侧天然植被破坏严重,低—低聚集的区域在逐渐扩大;南段草原区NDVI上升趋势显著,与气象因子的相关程度与其他三个生态地理区相比较低。


    In recent years, ecological deterioration trend of the mountain regions caused by global climate change and unreasonable resource development increased gradually. In this article, the spatial distribution and dynamic change of vegetation cover in the Greater Khingan Mountains are analyzed based on 8-km resolution GIMMS NDVI data from 1982 to 2006. Combining the meteorological data, the relationship between NDVI and climatic factors of vegetation variation response to climate change was discussed. The average NDVI values of the north and center were higher (0.65 and 0.63) than those of the northwest and south (0.57 and 0.51). The results showed that the NDVI values in Greater Khingan Mountains was increased more than decreasing in 1982-2006. The NDVI increased and decreased area covered about 80% and 20% of the whole study area respectively. Spatial changing trend of NDVI had great difference and most parts in different eco-geographical indistinct change. The decreased area was distributed in north, and center of the mountains. The region with marked increasing trend was mainly distributed on the south of the Greater Khingan Mountains. There was significant positive correlation between NDVI and climatic factors (temperature and precipitation), and NDVI had a stronger correlation with temperature than that with precipitation for the four eco-geographical region. By other factors, the weakest correlation was shown in the steppes vegetation cover region. The NDVI in Greater Khingan Mountains showed positive spatial autocorrelation in the whole region and similar NDVI were apt to aggregate together. A downward trend is detected in the high-high autocorrelation type, which tends to spread toward the lower reach of the north and center. The opposite result is obtained for the low-low autocorrelation type in the northwest.

    分别选取河南省、江苏省省会城市郑州市和南京市,以及典型县域原阳县和如皋市,将土壤多样性理论与方法应用于土壤和土地利用关联性评价中,对上述不同级别行政区域的不同时期(1986~1988年、2000~2001年、2004~2006年)遥感数据进行土地利用分类,计算了土壤和土地利用类型的构成组分多样性以及3 km×3 km网格尺度下的空间分布多样性,提出并计算了各研究区典型土壤和土地利用之间的关联系数,以此评价了河南省和江苏省典型区域的土壤和土地利用构成及分布特征。研究结果表明,20世纪80年代至本世纪初,中东部之间和省会与县域之间的土地利用构成组分多样性变化和空间分布多样性变化具有明显区别;城镇建筑用地的空间分布离散性增加,南京市的增加量为0.135,略高于郑州市增量,而原阳县增加量为0.244,明显高于如皋市增量;典型土壤同城镇建筑用地、交通运输用地和工矿仓储用地之间的关联性均不断增加,南京市的上述关联系数增加值高于郑州市,两县域无明显区别。


    Two typical provincial capitals (Zhengzhou and Nanjing) and counties (Yuanyang and Rugao) in central (Henan Province) and east (Jiangsu Province) China were chosen respectively as the comparative cases for pedodiversity and land use diversity correlative analysis by borrowing the recently developed pedodiversity theory and methods in soil geography field. Land use classification was worked out using remote sensing images in different times (1986~1988, 2000~2001, 2004~2006) for these studied areas before the calculation of the constituent diversity index and spatial distribution diversity index in 3 km×3 km grid scale of each soil and land use pattern were conducted and a connection index was proposed to evaluate the relationship between soil and land use pattern of the studied provincial capitals and counties. Results show that during the years from 1980s to the beginning of this century, the changes of composition and spatial distribution pattern of central and east China had significant differences. The spatial distribution diversity of urban construction land of the case areas all increased in which Nanjing was a little bit higher than Zhengzhou, Yuanyang was significantly higher than Rugao. The connection index of typical soil and typical urban land uses (urban construction land, transportation land and industrial and mining area) all increased in this period during which Nanjing was higher than Zhengzhou, Yuanyang was almost the same as Rugao. The introduction of diversity theory and methods to land resources evaluation was made in this study, by exploring the similarities and differences in the intrinsic link and urbanization characteristics between soil and land use in central and east China in different times and space spans, this study figured that the urbanization of Jiangsu Province in east China took place earlier and developed faster than Henan Province in central China, and the urbanization process of Nanjing was the most obvious one.

    距今约800 a前,长白山天池火山发生大规模普林尼式喷发,喷出的巨量火山浮石及火山灰毁灭性地破坏了长白山植被。由于受喷发倾角和强劲高空西北风影响,使各坡向火山灰和浮石的沉积厚度不同,东坡最厚,南坡和西坡次之,北坡最少。火山灰与浮石形成疏松的成土母质,在流水持续侵蚀下,对破坏后的植被演替产生了长期影响。利用野外调查和现有资料,论证了长白山植被分布独特性规律是长白山火山喷发及喷发物水蚀过程对生态系统作用的结果,确认火山喷发虽历经800多a,目前各坡向植被仍然处在演替的不同进程之中,呈现差异性分布规律。


    The Tianchi volcano experienced a serious Plinian eruption 800 years ago in Changbai Mountain. It dissolvingly destroyed the vegetation by the great amounts of volcanic ash and pumice. Due to the eruption dip angle and effect of the strong deflective northwest wind, the deposition thickness of volcanic ash and pumice was different in the four slopes of Changbai Mountain, with the main deposition being on the eastern slope, the second on the southern and western slope and, the least on the northern slope. They formed loose parent material. The flowing water erosion sustainedly affected the vegetation succession over Changbai Mountain after the volcanic destruction. The purpose of this study was to illuminate that the distinctive characteristics of the vegetation distribution is the result of influence on the ecosystem by the volcano eruption and flowing water erosion on eruptive material, and to affirm that although effects of the volcanic eruption had been lasted for more than 800 years in Changbai Mountain, the present vegetation is still in succession of different processes at four slopes, and exists various vegetation distribution rule.

    使用水文统计和交叉小波方法对西江流域1961~2005年径流变化特征及其与气象要素的多时间尺度的关联性进行分析。结果表明,径流量总体呈现减少的变化趋势,可能是人类活动引起流域内蒸发和入渗增加,使径流对降水的响应减弱造成的,径流丰枯变化基本与降水的波动相一致。气温对径流的显著作用主要集中在1990~2000年3~5 a周期上,径流对气温变化的响应时间为6~12个月;降水与径流在大部分时频域中呈同相相位变化,其相互作用主要集中在1992~2003年3~4 a和1980~2000年11~12 a周期上;大气环流变化对径流的影响主要集中在1965~1975年2~3 a及1993~2000年3~5 a周期上,对径流的影响可能是通过对区域降水影响实现的,径流对前一次环流变异响应时间为6~12个月,对后一次响应时间较快,时间的差异可能是下垫面的改变引起流域产汇流机制变化造成的。


    Using hydrological statistics and cross wavelet transform analysis, the variation characteristics of the runoff of the Xijiang River and the relation between the meteorological factors and the runoff in multi-time scales are detected in this research. The analysis indicates that the annual runoff decreases, which might be due to the weaken response of runoff to precipitation caused by increasing of evaporation and infiltration effected by human activities. The annual runoff fluctuation shows good correspondence with the precipitation. The cross wavelet analysis revealed that the impact of temperature to river flow occurred in the circle of 3-5 years in 1990-2000, in which the runoff shows lagging of 6-12 months to the temperature variation; the in-phase relations between the precipitation and river flow are found in almost all the time-frequency domains, good coherence can be found in the circle of 3 to 4 years between 1992 and 2003 and 11 to 12 years in 1980-2000; the impact of abnormal climate on runoff mainly occurred in the circle of 2 to 3 years in 1965-1975 and 3 to 5 years in 1993-2000, the impacts to the runoff variation might be carried out by the influence on the precipitation in the basin, the lag time between runoff variation and abnormal climate change event is 6 to 12 months in1965-1975 while equated almost to zero in 1980- 2000, this phenomenon might be caused by the changing of runoff production process effected by the changing of land use.

    摘要   HTML   PDF (713KB)

    采用交叉小波变换与小波相干方法分析了塔里木河流域近40 a来年径流量、年降水量和年平均温度的周期特征,结果表明:塔河流域年径流量、年降水量和年均温度存在2.0~6.0 a左右的显著周期变化,除卡群站年径流量周期变化不显著,其余水文站的年径流量周期强烈震荡主要分布于20世纪60年代中后期至70年代以及90年代以后;各站年降水量的显著周期主要分布于20世纪80年代以后;年均气温显著周期主要分布于20世纪60年代中后期至70年代。同古孜洛克和卡群的径流量显著周期变化主要受和田和莎车降水量的影响;沙里桂兰克1965~1968的径流量显著周期主要是阿合齐气温周期显著变化引起的,20世纪90年代以后阿合齐降水量成为影响径流量周期变化的主要因素;大山口的年径流量周期变化受降水量和气温的共同影响。阿拉尔径流量的周期变化在20世纪70年代主要受源流降水量显著周期变化。由于人口和耕地面积的迅速增加,源流区用水量增加,20世纪90年代以后降水量的周期变化没有引起阿拉尔径流量的周期变化。


    Annual runoff, annual precipitation and annual mean temperature at five hydrological stations and meteorological stations located in the Tarim River Basin are analyzed using the continuous wavelet transform, cross wavelet and wavelet coherence techniques. The results indicate that: 1) annual runoff, annual precipitation and annual mean temperature changes are of 2-4 years periods. Besides Kaqun station, the significant wavelet spectrum of runoff fluctuations is observed mainly during mid 1960s to 1970s and 1990s. However, the significant wavelet spectrum of precipitation and temperature fluctuations in all stations respectively are detected mainly in the after 1980s and late 1960s to 1970s. 2) Periodicity properties of runoff changes in Tongguziluoke and Kaqun stations are mainly due to precipitation variations. While Periodicity of runoff significantly changes in Shaliguilanke station are caused by temperature change in 1965-1968, but caused by precipitation after 1990s. Precipitation and temperature are together impact periodicity of runoff changes in Dashankou station. However, Periodicity of runoff significantly changes in Alaer station are influenced by precipitation. Because the population and cultivation area are notable increase which lead consumption of water to increase. The increasing precipitation not lead to the periodicity of runoff significantly changes after 1990.

    近几十年来的快速工业化和城市化进程深刻地影响了广州城市河流水体的形态演化。以地形图、遥感影像及相关社会经济数据为基础,探讨了1990~2010年广州城市河流水体的时空演化特征及原因。研究发现:广州城市河流水体在面积上呈现1990~2000年略增,2000~2010年骤减的趋势;岸线长度持续缩减;形状指数呈持续加速下降趋势,表明研究区河流水体的岸线复杂度不断降低,人类活动干预不断加强。不同区域河流水体的变化存在较大差异,1990~2000年增加的水体主要位于城市郊区的白云区和萝岗区,其原因主要是鱼塘的开挖和瓷土矿的开采;2000~2010年间研究区范围内各区均呈缩减趋势。研究时限内变化比率和速率最大的均是天河区,与广州城市发展的“东进”相一致。人类活动的影响是研究区河流水体变化的主要原因:减少部分主要由于建成区扩张的侵占;增加部分则包括新开挖鱼塘、瓷土矿开采遗留的矿坑积水、新营造的景观水体及其他特殊用途的水体。


    The shapes of urban rivers and water body were deeply affected by the rapid industrialization and urbanization in recent decades in Guangzhou. The article used topographic maps, remote sensing images and related socio-economic data as a basis data to research the space-time evolution of urban rivers and water body and its causes in Guangzhou in the past two decades. The results indicated that: 1) The changes of area of river and water bogy showed a slight increase trend in the first decade and a sharply reduce trend in the last decade, the area increased 9.11 km2 from 1990 to 2000, and reduced 32.37 km2 from 2000 to 2010. The water front length of river and water body showed a continuous reduce trend in the past two decades, the length reduced 26.49 km from 1990 to 2000 and 1 008.19 km from 2000 to 2010. The landscape shape index were 83.49 (1990), 80.19 (2000) and 71.83 (2010), which showed an accelerated decline trend, and indicated that the shape complexity of rivers and water body was decreasing and human intervention was strengthening in study area. 2) There were great differences between the changes of rivers and water body in different regions and periods. The increased parts from 1990 to 2000 mainly located in Baiyun and Luogang District in the outskirts of Guangzhou, because a lot of ponds had been excavated and porcelain clay lodes had been exploited in those areas. In 2000-2010, decrease happened in every district in study area as a common trend. The rate and speed of change in Tianhe District is the biggest in the past two decades, and that coincided with the "East" development direction of Guangzhou. 3) The changes of rivers and water body in study area were mainly affected by human activities. The reduced parts contain the occupation of the built-up areas, and increased parts contain new ponds, porcelain cay pits, new landscape water body and other water body for special uses.

    于2008年8月对博斯腾湖进行了系统的水质和水量监测,并结合近50 a来气候水文资料,进行了博斯腾湖演化过程和阶段特征分析。结果表明,目前湖泊最大水深为13.9 m,湖泊面积928 km2,蓄水量52.65×108 m3,湖水体矿化度平均1.48 g/L。近50 a来,博斯腾湖水质水量经历了3个明显的不同时期。1966年以前,湖泊处于1 048 m以上的高水位,矿化度低,湖泊受人类活动影响弱。第二个时期为1966~1996年,湖泊水位低,矿化度高,其中1987年湖泊水位处于历史低值而矿化度为最高。随后,湖泊水位明显上升、矿化度下降,湖泊扩展水体淡化。第三个时期为1996~2005年,湖泊水位处于历史高值段,矿化度有所下降但不明显。期间,人类活动对湖泊的影响显著,除流域农业用水影响外,城市和工业用水的影响也明显增加。最近几年,湖泊水位快速下降,并于2007年出现历史的低水位,湖泊矿化度也呈现升高趋势,鱼类种群和产量受人类强烈干预。另外,流域社会经济发展带来的城市化和工业化,也导致湖泊污染和富营养化,引起水质进一步恶化,湖泊面临新的生态环境压力。


    With the analysis of lake water quality and quantity data from a systematic and scientific survey for Bosten Lake in August 2008, and combined with climate and hydrological data in the past 50 years, the characteristics of Bosten Lake evolution were studied. The result showed that the deepest point of Bosten Lake is 13.9 m with the volume of 43.44×108 m3 and the area of 928 km2. The lake evolution has temporal differences in the last 50 years, and it can be summarized into three periods. In the first period, about 1966 years ago, Bosten Lake was influenced by weak human activities with high water level above 1 048 m and low water salinity. In the second period of 1966-1996, the lake water level is low, and the water salinity is high. Especially in 1987, the lake level is the lowest with the highest salinity in the last 50 years. Subsequently, the lake water level increased with decreased water salinity significantly. In the fourth period from 1996 to 2005, the lake had the historic high water level, and the lake salinity decreased but not significantly, which caused by increased agricultural, urban and industrial water demand. In recent years, the lake level dropped rapidly with the lowest level in 2007. The water salinity also has shown a trend of increasing. The fish stocks and production were in a strong intervention of human activity. In addition, watershed urbanization and industrialization in relation to socio-economic development, have also led to water pollution and eutrophication of Bosten Lake, causing further deterioration of the lake’s water quality, which inferred that the lake faces new environmental pressures.

    利用1961~2009 年江苏省逐日降水资料和南京站逐日水文资料,采用模糊聚类、小波分析、相关分析等方法分析了江苏梅汛期暴雨的气候特征及其与长江下游水位的关系。发现,在梅雨期间江苏省大部分区域都会出现暴雨,但也存在明显的地域差异,暴雨量的多寡一定程度上决定了该年梅雨量的丰枯;江苏南、北两个区域梅汛期暴雨均存在多时间尺度特征,但其年际和年代际振荡的周期和强度随时间的变化有不同表现。长江下游南京站6~7月的水位变化与梅雨期暴雨的年际、年代际周期变化和异常年份的发生有一定相似性,江苏南区梅雨期暴雨量与南京水位的相关性通过了0.10的显著性检验,可以认为南京站6~7月水位的高低与梅雨期暴雨具有一定的相关性。


    By using the daily precipitation data of Jiangsu Province and daily hydrological data of Nanjing City during the period from 1961 to 2009, the climatic characteristics of Meiyu rainstorms in Jiangsu and their relationship with the water levels over the lower reaches of the Changjiang River were analyzed based on the fuzzy clustering, wavelet analysis, correlation analysis and other methods. Results show that during the Meiyu period, although with a significant regional differences, rainstorms appear in most regions of Jiangsu, and the more or less of the maganitude of their rainfall to a certain extent determine the abundance or dry of the total Meiyu rainfall for a certain year. The rainstorms during Meiyu period both in North and South Jiangsu show multiple time scale features, but their period and intensity changes with time have different performance on the interannual and interdecadal time-scale. The water level from June to July in Nanjing has the similar inter-annual, decadal periodic variation and abnormal years, and the correlation between the rainfall and water level in Nanjing has passed the 0.1 confidence level of significance test, which suggests a certain close relevance between the water level and rainstorm in Nanjing during the Meiyu period.

    根据秦岭南北47个气象站1960~2011年逐月风速和气温资料,采用样条曲线插值法(Spline)、Pettitt突变点检验、气候倾向率和相关分析等方法对该区风速的空间分布、时空演变特征及其可能影响因素进行了分析。结果表明:① 秦岭南北风速空间分布呈东高西低、北高南低格局,按其大小排序为秦岭以北>秦岭南坡>汉水流域>巴巫谷地。四季风速排序为春季>冬季>夏季>秋季,均以秦岭以北最大。② 近52 a来,秦岭南北整体和各子区年平均风速呈现一致的显著下降趋势,下降最快的为秦岭南坡,最慢的为汉水流域。四季风速下降速率排序为冬季>春季>秋季>夏季。③ 年和季节尺度风速的突变集中出现在1969~1974、1978~1981和1990~1994年间,秦岭南北整体于1981年突变。④ 气象台站周边的城市化发展和风速测量仪器的更换都对风速的变化产生了一定影响,但都不是风速显著下降的主要原因,大气环流变化和气候变暖才是造成风速减小的可能原因。


    Wind speed time series have been subject to far fewer trend analysis than temperature and precipitation records, in part because of data homogeneity issues. However, understanding how evolution of the global climate system has been manifest as changes in near-surface wind regimes in the past and how near-surface wind speed regimes might alter in the future is of great relevance to the insurance industry, the construction and maritime industries, surface energy balance estimation, the community charged with mitigating coastal erosion, the agricultural industry, forest and infrastructure protection communities, and the burgeoning wind energy industry. Based on the temperature and wind speed data between 1960 and 2011 in the northern and southern region of Qinling Mountains, with the methods of Spline interpolation, Pettitt abrupt change point detection as well as correlation analysis, the distribution pattern, spatial and temporal variation of wind speed as well as the possible influential factors were analyzed. The result are as follows: 1) The wind speed presented an pattern which was big in south and low in north, big in east and small in west. According to wind speed, the order was northern and southern region of Qinling Mountains, Han River Basin and Ba-wu Valley , the order of season was spring, winter, summer and autumn. 2) Wind speed decreased significantly in the whole region and different sub-regions during the last 52 years, the decreasing rate in northern slope was the biggest and the smallest one was in the Han River Basin.The order of decreasing rate was winter, spring, autumn and summer. In spring, the wind of 77% stations decreased; In summer, 70% stations decreased, which mainly located in the east and north; In autumn, the increasing and decreasing stations accounted 23% and 77% respectively, but only 9% of them reached significant level, most of them lied in Han River Basin and Ba-wu Valley. In winter, 83%(17%) stations showed downward(upward) trend, 70% of them reached significant level, which distributed evenly in different sub-regions. 3) The annual and seasonal abrupt change happened mainly in 3 periods, which were 1969-1974、1978-1981 and 1990-1994, the whole region was detected abrupt change in 1981. 4) The development of city construction and change of observational devices had some effect on wind speed change, however, regional current change and global warming were the main reasons for wind speed decreasing.
