    史培军,孔锋,方佳毅
    地理科学. 2014, 34 (11): 1281-1290.   DOI: 10.13249/j.cnki.sgs.2014.011.1281

    采用1951~2010年中国659个气象站点的日值降水数据,以中国气象局颁布的降水强度等级划分标准为依据,分别计算1951~1960、1961~1970、1971~1980、1981~1990、1991~2000、2001~2010年的年代际暴雨雨量、雨日和雨强,并统计了其相应的站点数目变化。结果表明,在时间上,中国年代际暴雨雨量和雨日显著增加,暴雨雨强也呈现增加趋势;在空间上,中国年代际暴雨雨量和雨日呈现出从东南沿海地区向华中和西南及环渤海地区逐渐扩张的梯度增加趋势,年代际暴雨雨强远不如暴雨雨量和暴雨雨日梯变明显。中国暴雨1951~2010年年代际时空变化格局很可能是在全球变暖大背景下中国地势与城市化共同作用的结果。

    方修琦,郑景云,葛全胜
    地理科学. 2014, 34 (11): 1291-1298.   DOI: 10.13249/j.cnki.sgs.2014.011.1291

    基于现代全球变化研究中关于脆弱性和粮食安全的概念,把历史时期的粮食安全分解为粮食生产安全、粮食供给安全、粮食消费安全3个层次,以气候变化直接影响粮食生产水平为起点,分析气候变化-农(牧)业收成-食物的人均供给量-饥民-社会稳定性的驱动-响应链中的关键过程,指出气候变化影响的驱动-响应关系不能归结为简单的因果关系,诸如耕地、人口、政策、外来势力都会对气候变化的影响起着放大或抑制的作用。


    It is one of the core themes of the Past Global Change Sciences (PAGES) that to understand the mechanism and process of the past human-climate-ecosystem’s interaction in various spatial and temporal scales in order to improve the understanding of contemporary climate change impacts and adaptation. The topic is also the important theme of historical man/milieu relationships that is a big issue of concern by geographers. In this article, concepts of vulnerability and food security in the regime of Global Changes are used to illustrate historical climate change impact-response processes in China. Corresponding to the food access, food availability and food utilization, the food security of historical China is simplified to three levels of food production safety, food supply safety and food consumption safety. The food production safety was the base of food security which could reflect the social sensitivity to climate change. The food supply safety was the capacity of the society to accommodate the crisis of regional food security which could indicate the social capacity to response the impacts of climate change. The food consumption safety was the final state of food security. The insecurity of food consumption was essential for the occurrence of social instability impacted by climate change. The processes related to the impacts of climate change to grain productivity, food supply production security, individual food security, and social security are discussed. For human society, climate change means the changes of climatic resources or disasters. Impacts of climate change occurred from the direct impact on the grain harvest, then transferred further up to the sub-systems of economy, population and society mainly though the impact-response chain of climate change, agriculture harvest per capita food supply, famine, and social stability. However, the impact-response processes of climate change could not be attributed to a simple causality. The initial impact could be amplified or suppressed in feedback processes affected by many factors in each sub-system, such as arable land, population, policy, foreign forces, and so on. Both people’s spontaneous behaviours and the government's organized policies and operations played very important roles in all steps of adjusting the responses on the impacts of climate change. But each adjustment had its limitation under the given historical condition. The impact of climate change could be positive or negative. To a certain degree, even the negative impacts could be converted into new opportunity for development if right countermeasures were taken. This article has provided a framework on the impact-response processes of historical climate change. Further research should be carried out to measure the processes quantitatively on the base of the framework.

    以中国31个省域作为研究单元,以入境旅游外汇收入作为入境旅游经济的衡量指标,运用ESTDA框架,通过ESDA、LISA时间路径和时空跃迁等方法,从时空耦合的视角对中国2001~2011年省域入境旅游经济空间格局的时空动态性进行分析。研究发现:中国入境旅游经济存在弱正相关,表现为一种弱积聚格局,入境旅游经济空间差异呈现先缩小后扩大的趋势;东部沿海旅游经济发达地区具有更加动态的局部空间结构,而中西部旅游经济欠发达地区具有更加稳定的局部空间结构;湖北省在空间依赖方向上具有最大的波动性,而浙江省在空间依赖方向上具有最大的稳定性;中国入境旅游经济空间格局的演化具有较强的空间整合性,出现协同高增长趋势的省份主要集中在东部地区,而出现协同低增长趋势的省份主要集中在中西部地区;中国入境旅游经济的局部区域结构和空间自相关性非常稳定,具有一定的路径依赖或锁定特征。


    The importance of space to many socioeconomic processes has been gaining attentions and recognition. The spatial effect in regional differences studies is now an important theme in the literature. But, both spatial and temporal attributes of data are important, existing approaches focused primarily on one of these attributes. The empirical analysis should take into account that the nature of tourism economic development is both spatial and temporal. Using the methods of exploratory spatial data analysis (ESDA), LISA Time Path, LISA space-time transition measure and STARS (Space-Time Analysis of Regional Systems) software, this article analyzed the space-time dynamics of the inbound tourism economic development in China, measured by the foreign exchange revenue from China's inbound travel, throughout 31 Chinese mainland provinces from 2001 to 2011. Empirical results show that the inter-province inbound tourism economy is weakly auto-related, and the inter-province inbound tourism economic differences are dwindled first and enlarged afterward. By means of LISA time path analyses, this article finds that the local spatial structure of eastern coastal China tends to be more dynamic while the central and western regions are more stable. The longest three provinces of LISA time path are Beijing (3.804), Shanghai (3.625) and Tianjin (2.187) while the shortest three provinces are Shanxi (0.288), Ningxia (0.400) and Gansu (0.402). The maximum and minimum of the tortuosity of LISA time path are Hubei (16.816) and Zhejiang (1.171). Hubei has a most fluctuating local spatial dependence evolution in direction. According to the directional Moran scatter plot, the predominant direction involves downward moves of both a province and its neighbor. Following this are upward moves. Taking these together, there is striking evidence of strong spatial integration in evolution of spatial pattern of inbound tourism economy in China at the provincial level. According to the local Moran's I transition probability matrix and space-time transitions measures, the relative mobility of the local Moran transition matrices is relatively small. The frequency of type 0 transition is 0.987. This means that local inbound tourism economic structure and local spatial autocorrelation in China are very stable.

    柯文前,陆玉麒,俞肇元,王晗,陈伟,马颖忆
    地理科学. 2014, 34 (11): 1305-1312.   DOI: 10.13249/j.cnki.sgs.2014.011.1305
    摘要   HTML   PDF (808KB)

    综合运用城市流强度模型、改良Theil系数和K-means时空聚类法对2004~2010年中国地级以上286个城市对外服务能力的时空演变特征进行探讨,得到以下结论:① 城市流强度值的绝对量均有明显上升,但存在显著的区域非均衡现象,并与城市经济实力有较高的相关性。② 省内差异对城市对外服务能力的差异贡献率在58%~72%,是其空间尺度差异的主要来源。③ 时空演变表现出明显的阶段性和等级性规律,且空间等级性特征随阶段演进更趋明显。④ 对外服务能力的强弱和集聚强化趋势与城市流强度基数值大小和增速快慢有着紧密关系,一定程度上体现了基础乘数效应和循环累积效应配置下的非均衡特征。


    The present research on urban external service capability has focused less attention to its spatio-temporal evolution patterns. Aiming to solve this problem, this article comprehensively uses urban flow intensity model, the modified Theil index and K-means cluster as tools to analyze the spatio-temporal evolution patterns of external service capabilities of 286 central cities in Chinese urban system from 2004-2010. The conclusions can be drawn as follows: 1) urban flow intensity value has obvious rise during the study period, but the spatial differential features tend to remarkable, which has a high correlation with cities economy. 2) The modified Theil index shows that external service capabilities of central cities the differentiation in space are mainly from province inside, which gives a contribution rate from 58% to 72% to the national differentiation. 3) According to K-means cluster method, the spatio-temporal patterns of external service capabilities of Chinese central cities has the obvious evolution discipline of stage in time and hierarchy in space, and the hierarchy become more significant along with stage. 4) External service capabilities of Chinese central cities in the spatio-temporal patterns evolution tend to be more remarkable, and this trend has a close relationship with the urban flow intensity values and its growth rate. The relationship between external service capabilities of cities and the urban flow intensity values and its growth rate to a certain extent reflects the basic multiplier effect and the effect of cyclical accumulation can draw the regional unbalanced characteristics.

    摘要   HTML   PDF (879KB)

    通过对网站信息传输速度数据连续6个月的采集,编制出中国31个城市节点间信息传输速度矩阵。运用因子分析法计算出各城市节点对应的综合得分,并划分出等级,进而对最优等级/最差等级所涉及的城市节点进行频次统计,以分析信息联系通达性的等级特征。通过传输速度的等级划分,揭示高速连接线路和较高速连接线路的空间特征,最后对若干影响因素进行解释。研究发现:城市节点的输出和输入速度不一致,输出最优节点都处于主干网或与北京直接相连,输入最优节点与主干网关系不密切,输出和输入最差节点多处在网络末端;互联网信息联系通达性与传统城市等级间的正向对应关系发生偏转,传统等级靠前的城市节点信息传输通达性较弱;影响信息联系通达性的因素包括网络设置与网络组织、信息化建设与城市等级、网络服务运营商及其互通等,互联网服务商的供给和用户需求的对接有待改善。


    As a clear indicator, transmission speed has a significant effect on describing transmission accessibility of Internet information between the city nodes. Through the data of information transmission speed on the tachometer site, this article constructs the matrix of information transmission speed between the 31 cities nodes in China. It used factor analysis, to calculate the cities node corresponding composite scores and divide them into grades, to count the frequency the optimal grade/worst grade of city nodes, and to analyze the grade characteristics of information linkages accessibility. And then, through the hierarchies of the transmission speed, the spatial characteristic of the high-speed and higher-speed connection lines are revealed. Finally, several influence factors are explained. The research findings are as follows. The output speed and input speed city nodes is not consistent. The optimal output nodes are at the backbone or are directly connected with Beijing. The relationship between the optimal Input nodes and the backbone is not close. The worst output and input nodes are more at the net end. Forward corresponding relationship between Internet information transmission accessibility and the traditional city level changes. The information transmission accessibility of traditional high level city nodes is slow. The influencing factors of the information linkages accessibility include network Settings and network organization, information construction and city level, network service providers and communication, etc. The supply of docking Internet service provider and the demand of users needs to be improved. The cognition of information transmission rules can shed some light on Internet service providers, so that they could adopt flexible operation mechanism and service concept. It is practical significance to realize value docking between Internet service providers and users. Hereby, we bring forward the proposes: 1) The major networks should establish an overall scheme of network infrastructure, network framework between major networks, and establish end-to-end communication with its related regulations and standards, and solve the problem of the broadband resources waste and services quality. 2) The related administrative departments should further expand the Inter-Network broadband capacity in the poorer accessibility regions, solve the inter-network broadband occupation problems, and innovate the operation pattern between mobile and fixed Internet.

    以浙江省为例,分析与探讨基于引力模型的区域创新产出空间联系。根据最大引力线数量与区域创新产出联系总量确定了区域创新产出空间联系的中心城市,并结合断裂点公式测度了中心城市的创新产出辐射范围。研究发现,与2005年相比,2011年各县、市区的区域创新产出联系量与区域创新产出联系总量有明显增加,但区域创新产出联系的空间格局并未有显著变化,联系密集区主要集中于杭州、宁波两地;二、三级节点城市发生明显变化,而杭州市辖区始终是浙江区域创新产出联系的中心城市;中心城市辐射区范围增大,除宁波市辖区外,中心城市对节点城市的辐射效果均略有增强。基于此,提出加大区域创新投入,优化创新环境,完善城市、县市间道路建设,加强信息发展,缩短区域之间的硬距离与软距离,增强区域创新产出的空间联系等政策建议。


    Research on spatial linkage of regional innovation output and analysis of the radiation range in the central city have important practical significance to advance the spatial linkage of regional innovation output and promote the level of regional innovation output. This article analyzes the spatial linkage of regional innovation output based on gravity model, identifies the central city according to the number of the largest attraction linkages and total spatial linkages of regional innovation output and calculates the radiation range of the central city by breaking point formula in Zhejiang Province. Compared to the level in 2005 and 2011, the quantity of regional innovation output spatial linkage and total amount of linkages have increased obviously, but the spatial pattern of regional innovation output linkage has changed little with the concentrated areas mostly focused in Hangzhou and Ningbo. Although the cities with second and third level have had overt changes, Hangzhou City has always been the central city of spatial linkage of regional innovation output in Zhejiang. The radiation area in the central city has been expanded. The radiation effect of central city has strengthened slightly except Ningbo City. Based on this conclusion, this article puts forward some suggestions such as increasing the regional innovation input, optimizing the environment of regional innovation, improving and perfecting the construction of the highway and railway in cities, reducing the hard distance and soft distance between regions and promoting the spatial linkage of regional innovation output.

    地理科学. 2014, 34 (11): 1327-1336.   DOI: 10.13249/j.cnki.sgs.2014.011.1327
    摘要   HTML   PDF (479KB)

    通过问卷调查了解广州三种不同类型居住区即传统老城区、城中村、商品房小区居民的迁居情况,利用线性回归和多元Logistic回归,对不同类型居住区居民迁居后居住满意度的决定因素和居民迁居意愿产生的影响因素进行了研究。研究发现:不同类型居住区居民迁居后居住满意度的影响因素不同,总体上受社区归属感、住房所有权、设施完善程度影响较大,且与在本居住区居住时间呈负相关关系;迁居意愿的产生受很多因素的综合影响,不同类型居住区迁居意愿的影响因素有所差异。传统老城区家庭总月收入越低,居民对现住房越满意,越不可能产生迁居意愿,男性比女性更容易产生迁居意愿,高学历者更容易产生迁居意愿;城中村居民迁居意愿的产生是多种因素的复杂作用结果,其中社区归属感越强烈,越不可能产生迁居意愿;商品房小区居民的迁居意愿受户主年龄和婚姻状况的影响较大。研究结果表明西方的迁居理论,如生命周期理论并未能完全适用于中国,这与转型期中国城市复杂的住房构成和住房市场机制相关。


    With the deepening of housing reform, housing mobility in urban China is on the rise. Extant studies on relocation and relocation intention pay much attention on rural to urban relocation. Yet little is known about intra-urban relocation in Chinese cities. This study attempts to fill this void by presenting a line of empirical evidence in three different types of residential neighborhoods in Guangzhou, namely traditional inner city neighborhood, urban villages and commodity housing estates. Based on a questionnaire survey in three types of neighborhoods representative of the dominant residential patterns in contemporary Chinese cities, this paper examines the determinants of residential satisfaction and relocation intention of local residents in major urban neighborhoods. Specifically, we first run a linear regression analysis to examine the determinants for residential satisfaction after relocation; we then run a multivariate logistic regression to understand the determinants for residents’ relocation intention. Empirical results show that residential satisfaction in the three types of residential neighborhoods are influenced by different factors, but generally shaped by community attachment , housing property and housing facilities; meanwhile, residential satisfaction is negatively associated with residential time. While relocation intention is generated by a combined effect of various factors, and varies in different residential neighborhoods. In traditional inner city neighborhoods, residents’ relocation intention has something to do with the family income and the residential satisfaction. In the meantime male respondents are more likely to develop relocation intention than female, and residents who have got higher education tend to relocation. The situation is slightly different in urban villages, where residents with weak sense of community prefer to relocate. In addition, the result indicates that household head’s age and marital status significantly affect relocation intention in commodity housing estates. The diversified determinants of relocation intention in the three types of neighborhood are by no means sporadic, they are in fact closely related to the demographic composition, build environment, and development history of the neighborhood. Overall, findings in this research suggest prevalent western theories of residential mobility, e.g. life course approach do not necessarily applicable in the Chinese context. This study also offers a multilayer explanation to existing understanding of intra-urban relocation which tends to provide singular explanation either concentrating on socioeconomic indicators or neighborhood sentiments, or life course. To a great tent, residential satisfaction and relocation intention are shaped by a complicated set of determinants, reflecting the unique trajectory of housing reform and the diversified housing stock under market transitional. This paper has provided an updated and nuanced analysis of intra-urban relocation and enriched our understanding of complex mechanism and outcomes of residential mobility in post-reform urban China.

    地理科学. 2014, 34 (11): 1337-1343.   DOI: 10.13249/j.cnki.sgs.2014.011.1337
    摘要   HTML   PDF (478KB)

    将城市化与生态环境耦合脆弱的典型地区——黑龙江省东部煤电化基地作为研究区域,运用BP神经网络结合模糊综合评判法,利用2004~2010年指标数据,在对2010年城市化与生态环境耦合脆弱性与协调性现状评价的基础上,预测了2013~2022年城市化与生态环境耦合脆弱性与协调性,深入分析了城市化与生态环境耦合脆弱性与协调性关系未来演变趋势。结果表明:鹤岗、双鸭山、鸡西具有较重脆弱度,并且有向中度脆弱度过渡的趋势;佳木斯以中度脆弱度为主,但是向较轻脆弱度发展比较缓慢;七台河、牡丹江则以较轻脆弱度为主,但七台河重度脆弱度和较重脆弱度所占比重也比较大,牡丹江脆弱度情况明显优于七台河。鹤岗、双鸭山、鸡西协调度等级为中度失调;佳木斯与七台河协调度等级为濒临失调;牡丹江的协调度等级为良好协调。而脆弱性与协调性关系比较中,七台河脆弱性趋小值与协调性发展值关系为同时退化发展,但趋势比较缓慢;牡丹江则基本保持现有状态;其它城市均为同时向良好等级发展的趋势,但发展的速率和波动略有不同。


    The research area of this article is the coal-electricity base in eastern Heilongjiang Province, which is a typical coupling of urban and ecological environment. By the supporting of BP neural network and combining the method of fuzzy comprehensive evaluation, this article predicts the vulnerability and coordination of the coupling of urban and ecological environment from 2013 to 2022 in the coal-electricity base in the eastern Heilongjiang Province. The results show that Hegang, Shuangyashan, Jixi are the heavier vulnerability districts; Jiamusi belongs to moderate vulnerability, but developing speed is more slowly; Qitaihe and Mudanjiang are mild vulnerability, but severe vulnerability and heavier proportion in Qitaihe is relatively large, and vulnerability in Mudanjiang is better than that in Qitaihe; Hegang, Shuangyashan and Jixi are moderate disorders districts, Jiamusi and Qitaihe are endangered disharmony, and coordination grade in Mudanjiang is good coordination. The results of the relationship between vulnerability and coordination show that Qitaihe is slowly decline; Mudanjiang is basically flat; the others are slowly rising. It indicated that the overall vulnerability and coordination of the coupling of urban and ecological environment in the coal-electricity base in the eastern Heilongjiang Province are not optimistic and the reference of scientific significance could be provided to the eco-environmental protection and reasonable urbanization road by this research.

    摘要   HTML   PDF (776KB)

    基于警区层面的数据,以长春市为例,选取城市中典型的“两抢两盗”(抢劫、抢夺、机动车盗窃和入室盗窃)为研究对象,分析了长春市2008年不同犯罪的空间分布特征,并通过建立多元回归模型,探究几类犯罪空间分异的影响因子。研究发现,各类犯罪均表现出差异的空间分布规律和特征。回归分析的结果表明,抢劫、抢夺和机动车盗窃在不同程度上存在与之显著关联的影响因子,而入室盗窃则未能建立回归模型。最后基于相关结论,提出了犯罪地理研究对城市管理几点启示。


    Criminal geography which is one of the important branches in terms of crime studies is highly valued for its practicality. The studies concerning criminal geography in China are still at the beginning stage. More practical studies are needed so as to provide suggestions for the policing work. Different types of crimes usually have various distribution patterns as well as influential factors, which in turn requires deeper understanding in order to make wiser measures to counter crimes. Based on the crime data collected at the police-precincts level in Changchun, we choose the robbery, forcible seizure, vehicle theft and burglary as studies subjects and examine their distribution patterns in 2008 using the method of location quotient. Further, the influential factors of each crime are explored using the regression analysis and the mechanisms are also discussed. The results show that different crimes display various patterns and characteristics in terms of the spatial distribution. Generally, the robbery and forcible seizures tend to concentrate in the central part of the city and become less in the peripheral suburbs, while vehicle theft and burglary rates present an opposite pattern that the outside police-precincts are prone to higher crime risks. The regression analyses indicate that robbery, forcible seizures, vehicle theft are associated with some influential factors significantly in varying degrees. The robbery rates of Changchun are proved to be positively associated with the density of main roads and the proportion of commercial land use, and negatively related to the variables of the existence of vast industrial area and the number of high-rise buildings. The regression results also indicate that the forcible seizures rates are positively correlated to the variables of population density, the service activities as well as the existence of main commercial area. Meanwhile, the vehicle theft rates show a positively relationship with the existence of vast industrial area, while it exhibits negative relationship with the variables of the length of main roads and the distance between the centroid of the Jiedao and the nearest main roads. All the significant relationships between the different crime rates and respective influential factors can be explained according to the relevant theories and the specific socioeconomic characteristics of Changchun. The regression models indicate that the crime rates are a function of the characteristics of people in an area as well as the environment and characteristics of the area where people reside or work. However, we fail to build up a regression model with respect to burglary rates, which may be due to the fact that the variables we selected to conduct the regression analysis for burglary rates are too general and not able to explain the variance of burglary rates in Changchun. Finally, according to the conclusions drawn in the study, some implications for city management are proposed in the last part of this study.

    地理科学. 2014, 34 (11): 1353-1360.   DOI: 10.13249/j.cnki.sgs.2014.011.1353
    摘要   HTML   PDF (476KB)

    以系统论和人地关系理论为基础,从自组织性、周期性和波动性等3个方面总结了景区边缘型乡村旅游地人居环境的演变特征。以大南岳旅游圈为例,将旅游要素流的时空变换作为主要驱动因子,构建了景区边缘型乡村旅游地人居环境演变的动力模型,其演变过程经历了入侵、竞争、反应和调控4个阶段,每一个阶段的驱动力量和作用方式不同,所产生的人居效应有差异。其中,入侵过程可看做是旅游要素流的空间集聚对乡村旅游地人居环境的影响;竞争过程实质上是分化过程和共生过程的统一;反映过程是乡村旅游地人居环境系统对外界干扰的适应与调整;调控过程是厘清乡村人居环境时空格局与旅游发展过程之间的内在联系,寻求景区边缘型乡村旅游地人居环境建设路径。


    Human settlement of rural tourism destinations of edge type is a relatively independent and complex giant system. Its evolution characteristics and influence mechanism have distinct uniqueness, so new research idea and theoretical framework are required to carry on creative exploration. Based on systems science and man-land relationship theory, this article summarizes the evolution characteristics of human settlements in rural tourism destinations of edge type of scenic spot from 3 aspects such as self-organization, periodicity and volatility. The human settlement evolution of rural tourism destinations is the result of the interaction of self-organization and heter-organization. Under the influence of spatial-temporal transformation of tourism elements flow, the system evolution state presents a cyclical dynamic evolution. Because of the influence of uncertainty factors, this cyclical change shows a great uncertainty and diversity in evolution path and rate. Taking spatial-temporal transformation of tourism elements flow as main driving factor, using "Great Nanyue tourism circle" as a case study, this article constructs a dynamic model of evolution characteristics of rural tourism destinations human settlements of edge type of scenic spot. The evolution process is divided into four categories, which are processes of invasion, competition, reaction and regulation. Process of invasion embodies the impacts of spatial agglomeration of tourism elements flow on human settlements of rural tourism destinations. Process of competition is actually the unity of differentiation process and symbiosis process. Process of reaction is the adaptation and adjustment of human settlements system in rural tourism destinations to external interference. Processes of regulation can clarify the internal relations between spatial-temporal pattern of rural human settlements and tourism development, so as to seek constructional path of human settlements of rural tourism destinations of edge type of scenic spot. Inflow process of tourism elements flow is the unification of spatial process and social process. In the process of market oriented tourism development, competition process not only maximizes resources and location value, but also brings deep divisions and social inequalities. Government's effective control is particularly important because the intervening of heter-organization can guarantee the sustainable development of human settlement system of rural tourism destinations. Because of the complexity of rural tourism destination of edge type of scenic spot, the human settlement evolution is of diversity. Due to difference in type, location and development level of core scenic area, evolution process of human settlement of rural tourism destinations may be skipped or incomplete, so the universality of empirical research on "Great Nanyue Tourism Circle" requires further inspection. Comparative study on different types of human settlement evolution of rural tourism destinations of edge type of scenic spot has very important research significance, and it is also the important part of follow-up studies.

    以Ripley′s K函数为核心,通过城市区位与规模联立估计、地理权重引入、全局函数分解等手段,研究2001~2010年浙江省已有县级及以上城市空间分布的总体及局部估计问题,探讨城市空间格局与特征,以期揭示边界效应和市场潜力对浙江城市空间格局的影响机理。结果表明: 浙江省城市区位与规模的空间格局不一致,即前者是分散分布而后者是集聚分布,且随着空间尺度的增加,其分散或集聚程度逐步加强。 无论是行政边界还是海岸线,对浙江省城市区位与规模的空间分布演化有一定的负向作用。空间尺度越大,边界负效应越强。 在城市化发展过程中,浙江形成了3个各具产业特色的块状组团式城市聚集区,但边界负效应会抑制它们的发展,此时杭州、宁波将承担起服务全省经济的重要职责。 浙江城市规模因受市场潜力因素的影响会出现空间分布不均衡性。城市规模与市场潜力显著正相关,其程度却随着空间尺度的增加而减小。


    This article considers 3 different constructions of Ripley’s K function to deal with the global and local measure of urban spatial distribution in a particular area. Specifically, the first one allows us to identify and measure the distribution pattern of city location and size over space. By incorporating a geography-weighted variable into the K function, the second one may better capture the importance of border effects on the urban distribution disparities across regions. The third one decomposes the K function into the contribution of each individual observation, and provides the suggestion of spatial regimes on city distribution. Based on these three kinds of K function form, we investigate the spatial characteristics of city distribution at the county level in Zhejiang Province, given the population data and per capita income data between 2001 and 2010. The results are as follows. 1) The spatial distributions of city location are not inconsistent with those of city size in Zhejiang Province during this period. That is to say, the location distribution of Zhejiang’s cities has been more dispersed while the size distribution has been more concentrated across space at geographical scales over time. 2) In terms of provincial boundaries and coastlines, the border effects have negative impacts on the spatial distributions of both city location and city size. The negative border effects increase with geographical scale. 3) In the dynamic process of Zhejiang urbanization, three mass-clusters of urban accumulative regions with individual industrial characteristics can be found. However, the negative border effects would limit to the exposition of these urban accumulative regions. In this way, Hangzhou and Ningbo might have a public service responsibility to provide assistance for the whole province. 4) The uneven distributions of city sizes in Zhejiang Province might have been influenced by its market potential, that is to say, its city sizes positively related to market potential, and the growth rate of city population is less than that of market potential at geographical scales.

    对汉江上游现代大洪水高水位滞流沉积物(SWD)系统地采样测试分析,结果表明:汉江上游现代大洪水SWD沉积物性质是沙质粘土或粘土质沙、沙质粉沙或粉沙质沙。其分布特征大致分为两大类:安康段以上基本是以粉沙质沙或沙质粉沙为主,安康段以下基本是沙质粘土或粘土质沙。粒度成分和粒度参数都反映现代洪水SWD经过充分的分选,但是受多种因素影响,其粒径组成具有明显的空间变化。水库或大坝对大洪水SWD的粒度自然分布频率单峰曲线尖窄的形状没有明显的影响,而更多与其沉积的微地貌环境和水动力条件有关。


    Modern large flood events were marked clearly by grayish slackwater deposits of silty fine sand on the channel side. The most recent large floods in the upper Hanjiang River occurred on 19 July, 2010 with a peak discharge 21 400 m3/s and 19 September, 2011 with a peak discharge 21 000 m3/s as measured in the Baihe gauge station in the upper Hanjiang River basin. Modern flood slackwater deposits (SWD) were systematically investigated and sampled from upstream to downstream along the upper Hanjiang River in 2010-2012. These results showed that modern flood SWD is sandy clay, clay sand, sandy silt and silty sand in the upper Hanjiang River. There are two parts for the distribution of modern flood SWD. Sediment properties of modern flood SWD in the upstream of Ankang section are sandy silt and silty sand, but they are sandy clay and clayey sand in the downstream of Ankang section. The average clay (< 2 μm) content (5.9%) in the upper stream of Ankang section (LSC site) is higher than that in the down stream (clay content 2.1%). The average fine silt (2-16 μm) content (24.7%) in the upper stream of Ankang section (LSC site) is higher than that (17.0%) in the down stream. The average coarse silt (16-63 μm) content of modern flood SWD is 36.4% in the upper Hanjiang River. Clay and fine silt present high values in the upstream of LSC site and low values in the down stream of LSC site. On the contrary, sand (>63 μm) content shows that the low values (33.3%) in the upper stream of LSC site, whereas high values (44.2%) present in the down stream of LSC site. Mean size and medium size of modern flood SWD in the upstream of Ankang section are finer than that in the downstream. Mean size is larger than medium size of modern flood SWD along the upper Hanjiang River. Both sorting and skewness gradually decrease, but kurtosis gradually increases along the upper Hanjiang River. These results reflect that modern flood SWD are suspend deposits during highly energetic flood flows and deposited at long-term preservation. Grain size distribution of modern flood SWD presents obvious spatial variation along the upper Hanjiang River. Grain-size distributions of modern flood SWD are not only controlled by the lithology, topography, geomorphology and hydrology of the upper Hanjiang River, but also affected by the flood SWD sources, hydrologic conditions and micro-geomorphology of the SWD sedimentary environment. The shapes of particle-size distribution frequency curves in the modern flood SWD are more related to the micro-geomorphology environment and hydrodynamic conditions during flood periods, and reservoirs and dams have week influence on the shapes of modern flood SWD in the upper Hanjiang River. The shape of particle-size distribution frequency curve of modern flood SWD is an important proxy for identifying the palaeoflood SWD. These results provide a basic reference to mitigate flood disasters, palaeoflood science, and soil and water conservation in the upper Hanjiang River.

    暴雨内涝灾害是上海市最主要的自然灾害类型之一。在全球气候变化与海平面上升背景下,随着城市人口、财富的不断积聚,沿海城市的脆弱性增强,面临的暴雨内涝灾害风险形势更加严峻。基于情景分析视角,结合前人研究成果,分析、评价上海中心城区建筑暴雨内涝灾害脆弱性。结果显示:仓库与旧式住宅是暴雨内涝灾害中脆弱性程度最大的建筑类型。整体上,杨浦、普陀、徐汇区建筑脆弱性程度最大,长宁、虹口、闸北建筑脆弱性程度处于中等水平,卢湾、静安与黄浦区建筑脆弱性程度相对较低。


    Rainstorm waterlogging disaster, as one of the most devastating natural hazards in Shanghai, has badly affected residents’ lives and operation of urban system. As the accumulation of population and wealth, in the background of global climate change and sea level rises, the vulnerability of coastal city show an increasing trend which may lead a very serious situation of rainstorm waterlogging disaster risk. From the point view of scenario analysis, the vulnerability of the indoor property and structure of the buildings to rainstorm waterlogging disasters in central urban area of Shanghai was analyzed and evaluated combined with the previous studies. The main conclusions were as follows: 1) The vulnerability of different building types presents significant difference. The warehousing and the old-style residence are the most vulnerable building types when exposure to waterlogging disasters. 2) The loss rate, number, and types of damaged buildings increase as the precipitation intensity increases. 3) The structure of buildings was more vulnerable than the properties in the buildings, but the loss rate of building structure was lower than that of the properties in the building in the same condition. 4) The number of building with damaged structure was higher than that of building with damages property under the same scenario. 5) The spatial difference of the vulnerability of buildings is obvious. Over all, the rainstorm waterlogging disaster has the most serious effects on the buildings in Yangpu, Putuo and Xuhui District; the buildings in Changning, Hongkou and Zhabei District have medium vulnerability rank; the buildings in Luwan, Jing’an and Huangpu District have low vulnerability rank.

    利用河西地区15个气象站点1961~2010年月平均风速和最大风速日值资料,采用M-K突变检验、ArcGIS 中的IDW插值和小波分析等方法分析河西地区平均风速的时空变化趋势。结果表明:近50 a来,河西地区年平均风速呈明显下降趋势,其递减速率为0.14 m/( s•10 a) (α=0.001);该地区四季平均风速均呈减少趋势且减少趋势相同;平均风速的变化在空间分布上存在差异,具体表现为年平均风速的递减趋势是自西向东逐渐减小,瓜州和玉门是该地区减幅最大的区域,而乌鞘岭却呈现出微增的趋势;风速的长期变化具有一定的突变性,其年平均风速在1985年发生突变;该地区平均风速存在存在多尺度的周期结构特性,其变化周期为6、19和25 a。


    Hexi area is characterized with a vulnerable ecological system and severe soil erosion in the northwest of China. Analyzing the trend of the average wind speed is critical for wind resources management and soil erosion control in this region. Based on the monthly average wind speed of the 15 weather stations in Hexi area from 1961 to 2010 and using the methods of climate trending rate, 5 years running mean tread, Inverse Distance Weighted interpolation, Mann-Kendall abrupt change test and wavelet analysis method, the spatial and temporal trends of the average wind speed as well as the possible influential factors were analyzed in Hexi area of Gansu Province from 1961 to 2010. The main results are as follows: 1) The annual average wind speed was 2.9 m/s in Hexi area. The annual average wind speed obviously decreased at the rate of approximately 0.14m/(s·10 a) (α=0.001) in Hexi area during the period of 1961-2010. Furthermore, on the seasonal scale, the decreased rate of four seasons was similar. The mainly reason why the annual average wind speed decreased significantly was that the frequency of 5 or more than 5 levels of wind have decreased over recent years. 2) This trend has different spatial distribution in Hexi area. The average wind speed decreased significantly in the whole region and different subregions in recent 50 years, the decreasing rate in Guangzhou County and Yumen City were the biggest and the smallest one was in Wushaoling area. 3) Abrupt change was found in the long-term climate variation. The Mann-Kendall abrupt change test showed that the year of 1985 can be viewed as turning point of the abrupt change on an annual wind speed basis. While from the perspective of seasonal wind speed, the abrupt change points in summer and autumn appeared slightly earlier than those in spring and winter. The abrupt change of the average wind speed happened in 1985 in summer and autumn while that of spring appeared in 1987. The abrupt change of winter happened in 1986. 4) Morlet wavelet analysis revealed that average wind speed exhibited quasi-periodic variations of around 6 years, 19 years and 25 years.
