    以地方性理论为切入点,提出历史事件为地方性的来源。在洞庭碧螺春原产地苏州吴中区东山镇和金庭镇(原西山镇)进行访谈调查,了解地方性在洞庭碧螺春生产销售方面的作用。运用级差地租理论和垄断市场理论说明了当地通过占据历史事件发生地的“地方性”而获得了级差地租和垄断利润。研究结论为:① 历史事件和传说具有空间不可移动性,可以成为形成级差地租的因素。② 历史传说赋予地理标识产品的质量无法通过理化手段测量,因此会出现原产地之外的茶叶假冒当地茶叶销售获利。派生的建议是当地政府需要加强对地理标识产品的宣传及法律保护。


    Place is one of the core concepts of geography. A place is a unique geographical unit created by humans on the earth’s surface. Based on the theory of place, we carry out the interviews survey in the original production area of Dongting Biluochun Tea which is located in Dongshan Town and Jinting Town (formerly Xishan Town), Wuzhong District, Suzhou. We analyze the role of place in the production and sale of Dongting Biluochun Tea. Using theories of differential rent and monopoly market, this article explains how this place obtained differential rent and monopoly profits by being the site an important historical event. The conclusions are the following. First, a historical event happened in a specific place which cannot be moved to other place. This site became a factor that results in a differential rent. The legend of Biluochun Tea is considered equal to the investment by people of the land itself, which associates the local Biluochun Tea with culture quality which other Biluochun Tea does not have. The culture quality attracts some consumers and then forms the market demand which results in higher prices. Second, it is difficult to identify the specific features of a geographical indication product using a physical or chemical test, a feature which is associated with a specific historical event. The local tea producers are unable to obtain monopoly profits and thus it is difficult to execute a policy to protecting specific geographically indigenous products. Many tea makers and sellers in the past came to Dongshan and Xishan to sell fake Dongting Biluochun Tea for profit. To understand this practice, this study provides some assumptions or conditions. First, when calculating the differential rent, we make two assumptions: 1) there are no regional differences in the labor force and 2) the purchasing price of tea-leaves is equal to cost of planting the original tea. These two assumptions could affect the accuracy of the estimation of differential rent in this study. Second, when analyzing the structure of the monopoly profits, we assume that Dongshan Town and Jinting Town can be seen as a tea production group. However, there are so many producers and sellers in the production and sales market. Because of the many producers or sellers, it is obvious that competition exists in the market. The result is that the Dongting Biluochun Tea's market price is formed based on a “price game” between the many merchants, not determined by the rules in the monopoly market where the monopoly enterprise controls the output and sets the price. If the underlying assumptions or conditions described above change, the results of any analysis would likely be discounted. Further analysis needs to be done and any new conditions that might develop. Finally, based on the analysis above, our study provides two specific suggestions to local government shopping to successfully market Dongting Biluochun Tea: 1) to strengthen the brand value of Dongting Biluochun Tea and 2) to protect geographically indigenous products through specific laws and regulations.

    陶伟,丁传标
    地理科学. 2015, 35 (11): 1364-1371.   DOI: 10.13249/j.cnki.sgs.2015.011.1364

    家是地理学透视社会现象的窗口,家空间是地理学关注人地关系的微观尺度。作为住宅建筑与其居住主体发生联系的空间系统,家空间内部的组构差异可以反映不同的社会文化逻辑。空间句法作为一种定量分析城市形态的理论方法,在研究家空间形态与其社会文化逻辑关系时兼具定量和定性分析的优势。国外运用空间句法对家(family、home、house)空间的研究已日益成熟,而国内的相关工作却尚未涉及。首先阐述空间句法对家研究的基本过程与思路;其次,基于对国外相关研究的梳理、分析后,从家的“基因型”、家的“恒定”与“转换” 、家的“二元性”3个方面进行了归纳和总结,发现空间句法中的“空间”与传统地理学中的“空间”既不同又互补;不同民族文化、生活方式与其家空间之间存在组构关系;相同文化背景下家空间的组构具有时代性。地理学对家空间的关注一直比较薄弱,空间句法对家空间的研究为探究人与其居住空间之关系提供了新的视角。


    Home is a special point to view the social phenomenon, and home space is a micro scale to show man-land relationship by geographer. As the spatial system, which connects the housing architecture and the dwelling subjects, the difference of internal structure and organization display the different logic of cultures and societies.Architecture is a physical carrier of reflecting and inheriting culture, which contains rich meanings of culture, customs and rules.Through the study of living space form, we can peep the social change from microperspective. Space syntax theory, which is a quantitative means to analysis the urban morphology, can combine the quantitative and qualitative methods to research the spatial formation of home and its social cultural logic. In English literature, the concerned researches of home with the space syntax is increasingly mature, however, few researches in China adopt this research approach. This article firstly discusses the basic process and approach of the space syntax on home based on the space syntax international conference articles and published articles of journal of space syntax. Secondly, bases on the review of the concerned articles to summary in three subways-gene of home, home genre、 the "constant" and "conversion" of home、the duality of the home, to discover the difference and similarity of space in space syntax and traditional geography .We can get the following conclusions. The space syntax is not equal to the definition of space in human geography. Geography emphasizes the spatial distribution in the general case, and space syntax emphasizes the space ontology, those two definition is different and interacted. The configuration relationship exists between the different national cultures and lifestyles and their own home spaces, based on configuration, the home space constructs specific behaviors, communication interface, communication opportunities, so as to adapt to the needs of different social culture and behavior model. The configuration of home space under the same culture contains the obvious generational features. In the process of globalization and modernization, the home space maintains a constant with the traditions, a transformation to show innovation. The spatial boundary of internal and outside holy and civic, owner and visitor, female and male are constructed by the configuration of home.

    网络消费发展为区域经济增长带动新的动力,对网络消费的时空演变和区域联系特征研究,有助于深入的理解网络消费市场的空间组织关系。采用京东商城网上购物评论的用户信息数据,来研究网络消费时空演变趋势及网络消费区域联系特征。选取网络消费数量、万人网络消费人数、变异系数、Theil指数等指标,分析网络消费的发展过程和区域差异,结果表明网络消费增长早期较为缓慢,从2007年开始进入加速阶段,网络消费增长呈现东部高、中西部低的特征,并且东中西三大地带内发展差异显著。通过空间联系强度分析发现,中西部地区网络消费空间联系强度低于东部地区,但区域空间联系网络由不均衡逐渐向均衡状态转变。同时,研究表明网上零售企业的物流配送等要素布局对网络消费的区域联系具有显著影响。


    With the development of Internet and information technologies, the e-commerce economics has raised sharply in China, which drives online consumption increasing rapidly. Online consumption gradually becomes the new growth force of regional economics. Regarding the backgrounds supporting the economic and social development are not same in different regions, so the developments of online consumption are different with different regions. The online shopping consumer of Jingdong mall is taken as example in this article, to research its tempo-spatial evolution tendency and regional connection of online consumption, so as to provide some theoretical and practical evidences for the distribution of online shopping enterprises. The indices of the total number of online consumer, the number of online consumer per 10 000 people, coefficient of variation and the Theil coefficient are adopted to analyze the evolution tendency of online consumption in different regions. With the data of online consumer, we tried to explain the spatial and temporal distribution of online consumption as well as the evolutional regulation. The results show that the increasing of online consumption can be divided into two different stages: the online consumption increased slowly in the first stage (from 2003 to 2007), but the spatial differences of online consumption between different provinces increased in this stage. In the second stage (from 2007 to 2011) the online consumption grew rapidly, but the spatial differences began to decrease. The analysis with the “three belts” revealed that the growth of online consumption in Eastern China was faster than that in Central and Western China. The results of the model of regional connection intensity indicated that the intensities of spatial connection of online consumption in Western and Central China are obviously weaken than that in Eastern China, but the network of regional connection became balance from imbalance. More attention should be paid on the online consumption and regional connection in Western China. Several indices, such as economic development, residential income, the level of urbanization, social consumption, the level of informatization as well as the operation and logistics distribution of e-commerce enterprise, are adopted to analyze the influencing mechanisms of online consumption. Residential income is the leading factor which decides the online consumption difference between different regions. With the continual development of online consumption, the level of informatization becomes the key factor which influences the regional online consumption. Meanwhile, the distribution of self-built logistics system determinates the network structure of online consumption connection between regions. The research on the overall development evolution tendency and regional connection of online consumption can help to understand the relationship between the online consumption and the physical consumption in different regions, which could provide certain guide for the local development of online retailer enterprise and social consumption development.

    基于2000年、2010年人口普查乡镇(街道)数据,运用探索性空间数据分析、半变异函数等方法,分析江苏省人口分布的时空分异特征,并揭示其空间演化机理。结果表明:江苏省人口分布呈现较大的空间差异,全省层面上呈现南北人口密度高于中部的“凹”字型结构,城乡层面上呈现街道人口密度高于乡镇的“城乡二元”结构,以及沿江地区明显的“核心边缘”结构;研究期内江苏省人口分布的空间不均衡性和集聚性呈增强之势,长江以北镇域的人口密度大多降低而以南普遍增加,苏锡常、南京、徐州三大都市圈的人口集聚能力进一步提升,沿江地区成为全省规模最大的高密度人口连绵区;空间关联作用是引起江苏省人口分布格局变化的空间机理,而政策、区位、经济与自然环境等因素是造成江苏人口格局变化的主要动力。


    Since the reform and opening up, the large-scale migration in China has caused dramatic changes in population distribution, which has become a hot research field of human geography. Spatial pattern of population distribution has a typical character of scale dependency. Fine-scale estimation of the population distribution has been a huge challenge in the field of population geography. In China, sub-district is the finest administrative unit in official population census data. Thus, population density data at township level can be used to describe and characterize the population spatial pattern and changes elaborately, and support the optimized layout plan of Chinese population and government policy decision making. Sub-district boundaries across 13 cities in Jiangsu Province had been collected in this study. The national population census data were spatially joined to the boundary layer for population density calculation. Based on the fifth and sixth population censuses, using exploratory spatial data analysis, interpolation methods and semivariogram, the space differentiation and temporal variation of population density of all sub-districts in Jiangsu Province in 2000-2010 are explored, and further, the evolutionary mechanism of it is discussed. The results are reported as follows. In spatial distribution, the population density of Jiangsu Province was characterized by concave shaped structure, urban-rural dual structure, and core-periphery structure. Suzhou-Wuxi-Changzhou metropolitan area had the most widely dense population, and Nanjing City circle had the highest population density. In the evolution, the space differentiation of population density was becoming ever more obvious. Population density in the south of Jiangsu was generally increasing, but most towns’ population density was declining in the northern area. The variation of population density was presented spatial inequality. In evolutionary mechanism, spatial continuity and self-organization of population density have been intensified, and the spatial form of population density changed from decentralization in the initial stage to centralization. Additionally, the structural difference resulted from spatial association has become more and more obvious. The changes of population distribution were influenced mainly by policy and economic factors. First, regional strategies played a guiding role in the population distribution changes. Secondly, economic development reshaped the population distribution, and the population density had a significant positive correlation with economic density. Thirdly, location difference was the determinant. At last but not the least, physical geography difference had also affected the layout in a certain extent. This study expanded the research scale and dimension of the research in population geography research in China. The resulted population density dataset in 2000 and 2010 is expected to enrich the baseline data resources for population geography development in China.

    基于城市经济转型内涵,应用以综合赋权为基础的模糊物元模型和核密度估计模型等评价方法,对2000~2012年中国城市经济转型成效的时空格局演变进行分析。结果表明:2000~2012年中国经济转型低值地区发展速度提升较快,高值地区发展有减缓趋势,但整体呈现出较好的转型态势且区域间差距逐渐缩小。2005年特别是2008年金融危机以后取得成效并不显著。城市经济发展水平稳步提升,但空间格局变化甚微。经济规模扩张度、结构优化度、发展持续度在空间上呈现正向变化,转型成效明显;经济效益提升度却呈现出正反向回旋式变化,说明转型中政府政策的实施存在时滞效应且转型对就业产生了一定的挤出效应。城市经济转型的时空格局演变是多种因素综合作用的结果。历史性基础因素奠定了城市经济转型的基础,提升性动力因素为其注入了活力,二者相互作用共同决定了当前经济转型现状,未来影响城市经济转型的主要因素包括内生发展能力和政策导向因素。


    At present, the world is progressing toward the economic recovery of the international financial crisis, which is also a major adjustment period in the international industrial division pattern, as well as the focus of the world economy and the contrast of economic power. The overall economic growth of advanced economies remains relatively weak. At the same time, with the rapid development of the economy and urbanization process of China since the implementation of the Reform and Opening-up, the high resource environment load, along with contradictions among urban, resources, environment and economic development, has forced us to deepen economic reform and transformation. It is of great significance for the urban economic transformation process to promote regional economic growth, as well as the quality and efficiency of the economic development. This article, based on the connotation of urban economic transformation, takes the 15 deputy provincial cities of China as the research object, builds an index system which includes four dimensions, and undertakes research on the effects of urban economic transformation in China from 2000 to 2012 by means of the fuzzy matter element model based on comprehensive weight and the European approach degree comprehensive evaluation method. Then the article analyzes the temporal and spatial differences based on the results, by using the kernel density estimation model, thereby revealing the inner change rules, and determining the following conclusions: 1) The low-value areas’ development speed accelerates, while the high-value areas show a slow trend from 2000 to 2012 in the economic transformation of China. However, the overall pattern presents a good transition state, and the regional gap is narrowing. In 2005, especially after the 2008 financial crisis, the effects of urban economic transformation have been abating. 2) At the dimension level, urban economic development maintains a steady improvement, but the spatial pattern does not change significantly. At the same time, the expansion of economic scale, optimization of economic structure and degree of economic development show positive trends in the space, and the effects of transformation are obvious. In addition, the economic benefits of improving degree in the space shows a reverse rotary trend, which indicates that the implementation of the government policies in the process of transition exhibit a time-delay effect, and the transformation also produces a crowding-out effect of the society employment, which has a significant impact on the social investment and consumption, as well as the income of the residents. 3) The spatio-temporal evolution of urban economic transformation is the result of a large amount of factors. The historical basic factors lay the foundation for urban economic transformation, and the enhance power factors inject vitality into the urban economic transformation, while the interaction between the two factors jointly determines the current status of the economic transformation. The future of the urban economic transformation factors will be composed of the development ability in the region and the administrative factor. At the macro level, the administrative leading factor has a guiding effect on the economy; while at the micro level, urban development ability plays a core role, and the strategic positioning and improvement of the system and mechanism are important factors also affecting the urban economic transformation.

    构建旅游驱动下的张家界交通运输响应模型,提出交通运输通过增加投资响应旅游业发展,并引入旅游交通响应强度的概念,利用张家界1998~2011年相关统计数据,从静态和动态分析了张家界旅游交通响应强度的影响机制。结果发现:1998~2011年张家界旅游交通响应系数总体上呈上升趋势。这种上升趋势主要来源于区域经济发展水平、交通建设基础、旅游资源开发的空间结构、旅游产业地位4个主要因素的影响共同作用所生成地交通运输对旅游业发展的响应机制。


    Based on pressure-state-response (PSR) analysis theory framework, the article establishes a concept model to analyze mechanism of transportation response in tourism development. In it, firstly the conception of “the coefficient of tourism traffic intensity of the response” was brought in, secondly the Zhangjiajie transportation response model driven by tourism was set up, and finally the path was put forward that the regional tourism development puts a certain pressure on the development of transportation, and the transportation construction must respond to tourism development by increasing investment mechanism and cater to tourism development. Thus, tourism and transportation form a coordinated development of the relationship. Using the relevant regional statistical data from 1998 to 2011, we analyze the regional tourism traffic intensity of response through the model and response measure. The study finds that the coefficient of this regional tourism traffic response, on the whole, shows a rising trend from 1998 to 2011, which means that the coupling degree of tourism system and transportation system in this area shows an increasing trend, and the impact of tourism development on traffic construction investment are enhancing through the establishment of mechanism analysis model. This article further explores the influence of regional tourism traffic intensity of response mechanism, and the result is that this upward trend is influenced by four main factors including the regional economic development level, traffic construction foundation, the spatial structure of tourism resource development, and tourism industry status. Given that, the four ones, which work together, generate the response mechanism for the development of tourism.

    边缘型地区旅游发展的居民环境认同与旅游支持——以泸沽湖景区为例
    路幸福,陆林
    地理科学. 2015, 35 (11): 1404-1411.   DOI: 10.13249/j.cnki.sgs.2015.011.1404
    摘要   RICH HTML PDF (2371KB)

    边缘型地区旅游开发较晚,因生态环境和经济环境比较脆弱,容易受到来自现代化各种因素的影响,环境认同与边缘型地区旅游发展的支持具有相关性,并且环境认同也会影响居民对旅游影响的态度,进而影响旅游支持度。以泸沽湖为例,采用封闭式问卷调查法与结构式访谈法收集居民环境认同、旅游影响的态度和旅游支持的资料,并对数据进行回归分析。结果发现边缘型地区旅游地居民的环境认同较高,对旅游发展持相对谨慎的态度;边缘型地区居民的旅游支持还取决于居民对旅游积极影响的态度,而不是对消极影响的态度;居民对旅游的文化积极影响关注度略大于旅游经济影响。因此,边缘型地区的旅游发展要避免一些核心地区旅游发展过程中的环境破坏、过度商业化等问题,以环境保护为前提,以旅游利益共享为原则,统筹规划,实现旅游可持续发展。


    Peripheral areas are far away from the centre of population and economy, and at a disadvantage in the development of many fields. Many of these areas are characterized by lower agricultural income, less population, shortage of local investment and so on. Because of the fragile ecological environment and economic environment, later tourism developments and also easily affected by various factors from modernization, these areas have attracted domestic and foreign tourism researchers’ much attention in resent years. The article assumes that environmental identity significantly correlates to residents’ identity of tourism development in these areas, and it will influence attitudes to tourism impacts and residents’ support. This is of great importance to fragile environment in peripheral areas, and then it would facilitate the residents’ support for tourism to be a strong development momentum the tourism sustainable development. The study takes Lugu Lake as a typical case of tourism destination of peripheral areas. The methods of closed questionnaire and structured interview are adopted to collect information of residents’ environmental identity, attitudes of tourism impact and support. Subjects were those administrative villages or natural villages around the lake with developed tourism. Multistage sampling is adopted to select households and then respondents. Semantic differential scale consisted of seven bipolar statements were used to measure environmental recognition, responses range from 1 to 5. 1 represents agreement with one bipolar statement and 5 reflected agreement with the other extreme. And attitudes to tourism impacts and support were measured by 22 items asking residents their level of attitudes and support with specific forms of tourism development on a 1-5 Likert scaling where 1 represented ‘strongly disagree’ and 5 represented ‘strongly agree’. To detect scale dimensionality, an exploratory factor analysis with principal component method was conducted for each construct. And then stepwise multiple regression analysis was used to test the proposed model and hypothesized relationships. Results indicate that there is a direct negative relationship between environmental identity and residents’ attitudes towards the positive impacts of tourism, and a positive relationship between residents’ attitudes to the positive impacts of tourism and residents’ support for tourism, and a directly negative relationship between environmental identity and residents’ support for tourism. The main reason lies in the high environmental identity and residents’ stronger attitudes to the positive impacts of tourism. Findings confirm that residents’ environmental identity of these areas is relatively high, and residents remain relatively cautious on the development of tourism. The residents’ support for tourism also depends on the attitude of residents towards positive impact on tourism, instead of negative attitude. Residents’ attention on the positive impact of tourism on culture is slightly larger than the economic impact of tourism. Therefore, the tourism development of peripheral areas should avoid some issues such as environmental damage and excessive commercialization in the tourism development process of the central areas, and take environmental protection, shared interests, and overall planning as principles to achieve sustainable development of tourism.

    利用极差、标准差、变异系数、基尼系数、赫芬达尔系数、首位度等方法,以2000~2013年皖南国际文化旅游示范区各地市的国内旅游收入、国际旅游收入以及旅游总收入为分析对象,揭示皖南国际文化旅游示范区区域旅游经济差异的时空特征。结果表明:皖南国际文化旅游示范区旅游发展规模呈现不平衡态势,各地市间绝对差异较大,相对差异逐渐减小; 示范区内各地市的国内旅游收入差异和旅游总收入差异小于国际旅游收入差异;2000~2013年皖南国际文化旅游示范区国内旅游收入和旅游总收入的基尼系数介于0.30~0.41之间,处于相对合理区间,国际旅游收入的基尼系数介于0.50~0.67之间,差距较大,甚至很悬殊; 国内旅游收入和旅游总收入城市首位度指数始终介于1.2~2.2之间,相对较大,第1位城市对第2位城市形成稳定的规模优势,而国际旅游收入城市首位度指数大部分时间介于3.0~9.5之间,第1位城市对第2位城市形成绝对的压倒性的规模优势。通过对皖南国际文化旅游示范区旅游经济差异成因进行分析,表明区域旅游经济规模与旅游资源禀赋、旅游基础设施建设、交通区位条件好坏、政府政策支持以及经济发展水平高低之间的关系密不可分。


    It is of great significance to accelerate the development of the Demonstration Area of the Southern Anhui International Cultural Tourism under the circumstance of rapid tourism economy development in China today. It can help promote the regional coordinated development, accelerate the transformation of economic mode, carry forward the fine traditional Chinese culture, and advance the construction of a better Anhui Province. By using such methods as Range, Standard Deviation, Coefficient of Variation, the Gini Coefficient, the Herfindahl Coefficient and the Primacy Index, with the domestic tourism revenue, international tourism receipts and total tourism revenue of each city in the Demonstration Area in 2000-2013 as the research object, the article aims at revealing spatial and temporal characteristics of regional differences of tourism economy in the demonstration area so as to provide the basis for its coordinated and sustainable development. The results are as follows. First, the scale of tourism development in the area is unbalanced, with absolute differences among regional cities being big and their relative differences being reduced. Second, disparities of domestic tourism revenue among regional cities are less than those of the international tourism income. Third, the Gini Coefficient of domestic tourism revenue and total tourism income in 2000-2013 in the demonstration area is in a relatively reasonable range, ranging from 0.30 to 0.41, while the Gini coefficient of international tourism receipts changes from 0.50 to 0.67, showing that the gap is big, or even very huge. Finally, as for domestic tourism revenue and total tourism income, the urban primacy index in the first two cities varies from 1.2 to 2.2, with the top first city having more stable scale advantages than the second one. When it comes to international tourism receipts, the primacy index has been about 1.5 in the recent years and been between 3.0 and 9.5 in the other years, showing that the first city forms an absolute overwhelming size advantage over the second one. By analyzing the causes of economic differences of tourism in International Tourism and Culture Demonstration Zone in the Southern Anhui Province, it shows that economic scales of regional tourism bears a close relationship with endowments of tourism resources, tourism infrastructure, geographic traffic conditions, support of government policies and local economic growth.

    According to different life cycle stages of the three ancient towns (Zhouzhuang, Jinxi, Qiandeng), the article selects five variable indicators (waste water, excrement, solid waste, SO2 and NOx) and per capita income of monthly time series data from 2009 to 2013, uses Eviews 6.0 measurement software, and tests the environmental Kuznets curve fitting of tourism waste. The results are shown as follows. 1) There are differences between tourism waste emissions and per capita income in ancient town of different life cycle stages. The "U" curve relationship, "U" curve relationship and monotonically linear relationship existed between waste water, excrement and solid waste emissions and per capita income in the relatively mature stage of Zhouzhuang. The inflection point of "U" curve of waste water emissions is 28 197.63 t, the inflection point of "U" curve of excrement emissions is 10.82 t, and per capita income Ln(R) increased by 1%, solid waste emissions Ln(L) would increase by 0.051% of Zhouzhuang; Corresponding indicators showed the "inverted U" curve relationship, "N" type curve relationship and "N" type curve relationship in the stable development stage of Jinxi. The inflection point of "inverted U" curve of waste water emissions is 13 741.46 t, the two inflection points of "N" type curve of excrement emissions were 5.80 t and 5.54 t, the two inflection points of "N" type curve of solid waste emissions were 125.90 t and 124.81 t of Jinxi; Corresponding indicators showed the monotonically linear relationship, "inverted U" curve relationship and linear rise in the rapid development stage of Qiandeng. Per capita income Ln(R) increased by 1%, waste water emissions Ln(Ws) would increase by 0.124%, the inflection point of "inverted U" curve of excrement emissions is 12.15 t, per capita income Ln(R) increased by 1%, solid waste emissions Ln(L) would increase by 0.017% of Qiandeng; The environmental impact is small of waste gas in three ancient town. 2) One-way Granger causality relationship existed between tourism economic development and environmental quality change in the ancient towns with different life cycle stages. Per capita income was respectively the Granger cause of waste water, excrement and solid waste emissions, but waste water, excrement and solid waste emissions were not the Granger cause of per capita income in the three ancient towns. 3) The environmental impact of tourism waste are different in ancient town of different life cycle stages. Water environment index COD and NH3-N showed a trend of decline, there was no significant difference between the interannual of TP in Zhouzhuang. There were no significant differences between the interannual of COD and NH3-N in Jinxi. COD decreased significantly since 2009, NH3-N showed a trend of increase, TP showed a trend of decline in Qiandeng. 4) Strengthening tourism waste management is the key factor to realize sustainable development of ancient town tourism.

    以典型样地基准化法结合约束性线性光谱分解法对南昌市主城区1995年以来不透水面增长格局演变及其模式进行研究。结果表明: 研究区不透水面格局呈“较散-集中-扩散”发展的总体规律,主导模式从“以轴线延伸式”向“以卫星填充式、零星飞地式增长”进行转变; 格局变化与经济社会发展阶段演变、便捷技术及材料的广泛使用,地区土地政策、城市规划、城建投资等因素有关; 制定理性的城市规划、重点关注郊区用地过快增长、推广使用绿色透水建材、透水的施工技术等可减缓研究区过快增长的不透水率。


    Impervious surface Area (ISA) is an artificial surface as the specific components, mainly by the hard road, parking lot, a square and a roof and other buildings composition in the city. Because isolation of surface water infiltration into the soil, impervious surface can cut the urban surface and subsurface hydrological connection. It is regarded as important elements on process of urban hydrological cycle, thermal cycling, local climate and biodiversity changes, has become an important indicator of urbanization healthy and quality of the city growth. So it increasingly becomes a hot research issues in geography, ecology, urban planning, environmental science and remote sensing information in recent years in China. But the long-term monitoring and longitudinal comparison of impervious surface is a challenging work. Based on the exited correlation between typical samples’ impervious rate, an innovation research method that we called it Reference model of Typical Samples (RTM) was constructed and used to do comparison of impervious surface in historical yearin this article. Besides, the paper examines the impervious surface area growth pattern in recent 20 years in Nanchang main urban areawas applying of Constraint Linear Spectral Unmixing Method(CLSUM). This study shows that the overall development shows the impervious surface area percentage (ISP) increases obviously in Nanchang main urban area in recent 20 years with the percentage of annual increase on 0.09% and the area of annual increase on 32 hatches. The growth pattern shows “decentralized-concentration-diffusion” expanding mode in study area, with the transition of impervious surface high-growth area from urban centers to urban fringe district. The preexisting dominant “road extending” developing mode is gradually transformed into “Satellite filling” mode and “Sporadic enclave” mode, with its contribution of ISP from 23% in 1995 to 11% in 2014 and at the same time Satellite &Sporadic enclavemode contribution to study area ISP from 63% to 71%. From the macro view, the impervious surface pattern evolution was affected by the development of social economy and the spreading of convenient engineering technology and materials. On the micro level, this kind of surface changing is also impacted by land policy, urban planning and the investment of urban construction, et al. The present study found that the excessive growth of impervious surface can be effectively reduced by: 1) Rationally planning city expansion; 2) Paying more attention to the excessive growth of construction land in suburban areas; 3) Promoting the use of green permeable building materials; 4) Developing the new construction technology used for improving permeability. The before-and-after comparison of the impervious surface pattern can be unified into a bench mark by joint applying of RTM and CLSUM, with elimination of certain errors. So the reference model of typical samples lays an analyzing foundation for the long-term monitoring and comparing of urban impervious surface changing.

    Heavy precipitation is a crucial nature factor of flood. The return period of the extreme value of precipitation depth is the most significant reference of the design standard of flood prevention facilities in an urban or a basin. In this article, the series of annual, summer and winter maxima of precipitation depths for 1-day, 2-day and 3-day durations measured at ten selected stations in China are analyzed, using five commonly used hydrological statistical distribution functions. The distribution functions applicable for these stations were measured using the Kolmogorov Smirnov (K-S) and the Anderson Darling (A-D) tests. The results show that: 1) The summer maxima series shows higher standard deviation and larger differences between distributions than other maxima series and the annual maxima occur mostly in summer; 2) The Generalized Extreme Value (GEV) distribution, the lognormal (LN) distribution and the Pearson III distribution perform were better in the imitative effect test of goodness of fit, and the degree of curve difference is smaller; 3) Differences between estimates of rainfall with return periods were shorter than 25 years are smaller; 4) Estimates of precipitation can change significantly depending on the probability distribution being used, particularly for the summer series; 5) Suitability curves present seasonal difference. By statistical analysis of precipitation maxima, the precipitation is concentrated in summer; due to the disperse and skewness of precipitation series, and the appropriate distribution functions are quite different in different season periods; 6) In some extreme rainfall sequences, two curves of linear fitting are almost the same. Even if the return period extending to 100 years, the difference quantity of two curves is only a few millimeters. In this situation, the results of small probability rainfall events are more reliable; 7) There are differences among 1-day, 2-day and 3-day durations of precipitation depths, the probability distribution of 1-day maximum precipitation fits better. When carrying out statistical analysis of hydro-meteorological extremes, various probability distribution function and test methods should be taken for calculating, to reduce the uncertainty of single calculation. In this study, experimental analysis of 10 sites demonstrated that the Pearson III is not suitable for all sites. It is suggested here that the estimation of extreme precipitation should take into consideration the range of extreme values estimated by the best-fit distributions identified by more than one test as an approach to assess uncertainties related to extreme rainfall analysis.

    Northeast Asia is an area with relatively concentrated resources, complex ecological environment pattern, diverse climate condition, significant relationship between people and land resources. The climate change in North Asia not only directly affects the local ecosystem succession, resource exploitation and economic development, but also plays an extremely important role on global climate change and the ecological balance. In this research, we choose the North-south transect of Northeast Asia as the study area,and make systematic analysis of the spatio-temporal characteristics of climate changeduring the past 30 years by means of statistical analysis, linear trend analysis and accumulative anomaly curve method and used the temperature and precipitation daily observation data of NCDC meteorological stations. The main conclusions are as follows: 1) North-south gradient zonal differentiation of temperature and precipitation issignificant inthe North-south transect of Northeast Asia. From north to south, the temperature and precipitation gradually increased. 2) During 1980-2010, the periodic changes of temperature and precipitation are very obvious. Temperature overallentered the warm phase after 1996, and precipitation showed reduction in south and increase in north in the spatial differentiation pattern. 3) The temperature changes mainly showed warming trend. The significant warming zones with annual increase rate of more than 0.05℃/a, occurred in the following areas: the northwest and south of the subarctic coniferous forest zone, temperate desert zone, central area of temperate steppe zone, and west area of the temperate mixed forest zone. 4) The spatial differences of precipitation changes are significant. The areas with the annual precipitation reduction rate of more than 5 mm/a are in the following areas: temperate steppe zone, temperate desert zone and the southwest region of temperate mixed forest zone. And the area with the annual precipitation increase rate of more than 5 mm/a are in the following area: western area of arctic tundra zone, northwestern and southern area of subarctic coniferous forest zone and southeastern regions of temperate mixed forest zone. The analysis of spatial and temporal characteristics of climate changesin North-South Transect of Northeast Asianot only provides a scientific basis for the future climate change studies of the whole Northeast Asia, but also has important significance to guide the human society and economic activity to adapt to the impact of climate change.

    对浙江新昌玄武岩、花岗岩风化壳红土和江西南昌第四纪沉积型红土剖面的磁学特征进行了分析,结果表明,同一气候区内风化壳红土的磁学特征受母质特征影响较大。随着风化强度的增加,强磁性的玄武岩风化壳磁化率先减小后增加,磁性矿物颗粒先变粗后变细,弱磁性的花岗岩风化壳磁化率逐渐增加,磁性矿物颗粒逐渐变细。第四纪沉积型红土剖面中,均质红土磁化率远大于网纹红土,磁性矿物颗粒亦较网纹红土层细。这些差别说明了第四纪沉积型红土剖面中均质红土与网纹红土不完全相同的物质来源。


    Kind of red, loose or semi-cemented sediment was widely distributed in tropical and subtropical regions of China, called Quaternary Red Clay (QRC). The causes and definitions of QRC were argued intensely. Depends on matrix, the QRC can be broadly divided into two types, Sedimentary Red Clay (SRC) and Laterite Weathering Crust (LWC). The SRC, development on all kinds of Quaternary sediments, always got similar profile configuration. The layer of SRC profile, from top to bottom, was Homogeneous Red Clay (HRC) or Yellow-Brown Earth (YBE), Vermicular Red Clay (VRC) and weathered gravel or bedrock; LWC was a kind of residual soil, formed by different types of bedrock weathering and widely distributed in tropical and subtropical regions. Representative LWC profile was generally contained weathered red soil, semi-weathered layer and bedrock. In this article, magnetic characteristics of basalt and granite weathering crust in Xinchang, Zhejiang Province, Quaternary SRC in Nanchang, Jiangxi Province were analyzed. The main characteristics of LWC are that, magnetic characteristics distinction of two kinds of weathering crust in the same climate zone was relatively large and the magnetic characteristics were determined by the matrix; Magnetisability of basalt weathering crust increased after a small decrease with the increasing weathering intensity; Magnetisability of granite weathering crust increased with increasing weathering intensity. Intense weathering made mineral particles tapering and antiferromagnetic minerals reduce in these two kinds of weathering crust. The main characteristics of sedimentary red clay were that, magnetisability of HRC was greater than VRC at least one order of magnitude. The content of antiferromagnetic mineral in VRC was much greater than the HRC. The content of Pseudo-Single Domain and Multidomain grain in VRC was much greater than the HRC. The magnetic characteristics change rule in SRC did not meet with the weathering rule prove that maybe HRC and VRC got different provenance in Quaternary sedimentary red clay profile.

    在总结以往LS因子相关算法研究基础上,结合McCool的LS因子参照值,对LS算法的适用性进行评价分析。研究表明,除去复合算法和Remortel修正算法外,其他不同算法LS因子值都小于参照值;研究区LS因子值的最优算法为基于Remortel迭代运算的修正算法;其次为结合刘宝元的陡坡公式和Remortel改进L指数因子迭代运算的复合算法,以及Remortel第4版AML程序算法;再次为B?hner算法,而Moore算法和Desmet算法,由于其与参照值的相关性相对较差,而且其RMSE相对较大,不推荐在该区使用。


    The Universal Soil Loss Equation (USLE) model and its principal derivative and the Revised Universal Soil Loss Equation (RUSLE) model have been widely used in the past decades. However, the use of USLE and RUSLE has been limited by the inability to generate reliable estimates of the LS factor. Several different LS factor algorithms from the previous studies were briefly summarized in this article and their applicability was evaluated in Wohushan reservoir basin. According to the Agriculture Handbook No. 703 and 537 of US Agriculture Department, the LS-values in McCool's table are the same as the LS algorithms in USLE/RUSLE. Although there is some regional heterogeneity in the specific regional applications for LS calculations, the difference is very limited within a certain slope length and slope gradient. Based on these reasons, the LS-values from McCools are primarily preferred as the reference value. There are four basic LS algorithms which were Remortal, Moore, Desmet and B?hner used to be compared with reference value. In addition, two revised algorithms, i.e. the improved iterative Remortal algorithm and complex algorithm, were presented. The slope-length exponent (m) in the former algorithm was revised from low rill/interrill ratio class to moderate class. The complex algorithm was composed of L-factor and S-factor from different research, of which the latter was from the above mentioned improved algorithm of Remortel and S-factor was made up of S algorithm from McCool and that of Liu BY. In this article, the LS values of the six above algorithms were compared with that of McCools by RMSE (the Root Mean Square Error), the correlation coefficient and the slope of the regression equation. The results indicated that, other than the improved algorithm of Remortel and the complex algorithm, the LS-value obtained by different algorithms are all less than that of reference value. It is also found that the optimal algorithm in the study area is the improved iterative algorithm of Remortel, followed by both the AML program of LS factor from RUSLE Version 4 of Remortel and the complex algorithm. The B?hner’s algorithm could also be used in this area. However, the algorithms from Moore and Desmet were recommended not to use in the study area because of their relatively higher RMSEs and relatively poor correlation coefficients.

    The loess-paleosol sequences on the Chinese Loess Plateau (CLP) record the evolution of East Asian Monsoon. Soil color, a sensitive proxy of paleoclimate, has long been used for soil identification and qualitative determination of soil characteristics. Meanwhile it is also used as an indicator of field soil physics, chemical and biological properties as well as of occurrence of soil process. Here we focus on the characteristics and significance of soil color of Chaona loess-paleosol Sequence in CLP since the last Interglacial period. The study area is located near the town of Chaona (35°7′N,107°12′E) in the central CLP. The loess deposit of sequence is 175 m thick and contains 33 paleosol units. The paleosol within the loess is brownish or reddish with substantial clay skins developed and carbnate nodules are scattered commonly below the soils. Our attention has been given to studies of the last glacial-interglacial cycle and the overlying Holocene paleosol (S0). The last glacial loess (L1) consists of two primary loess units (L1LL1 and L1LL2), separated by a weak soil complex (L1SS). And the last interglacial paleosol (S1) can be further divided into three subunits, including two moderate developed paleosol complexes (S1SS1 and S1SS2) and a loess horizon (S1LL). We compared chromatic indexes with magnetic susceptibility. The results indicated that lightness L* can be good correlation with the ratio of Hm and Gt that reflects the precipitation. Lightness L* has a positive correlation with the ratio of Hm and Gt in since the last glacial period, but there is obvious negative correlation between lightness L* and the ratio of Hm and Gt during the last interglacial period. Meanwhile we find that a positive correlation exists between a* and the ratio of Hm and Gt in the section, which reflects hydrothermal conditions in the soil development period. The value of b* primarily influenced by the content of Gt can be used together with χlf in order to reproduce the development degree of the soil. In contrast to magnetic susceptibility, chroma indexes from S1 paleosol are characterized by high-frequency and high-amplitude variations, which also documents the weak loess-paleosol sequences during the last interglacial period (S1). Furthermore, a* and b* are the major factors that influences L* value significantly. Therefore, Chroma index, a proxy that documents the sensitive and great evidence of climate variations, can be used to develop the complementary study with magnetic susceptibility, which can reconstruct the process of paleoclimate reasonably and reliably.
