摘　　要：行政区划的调整导致城市群的空间结构发生变化,因而对区域的城镇体系和经济体系乃至整个区域的发展产生重大影响。以长江三角洲为研究区域,采用国家基础地理信息系统提供的县级以上境界面状数据,使用ArcGIS软件,通过ArcMap ArcToolbox中的自带工具、ArcMap VBA和Google Maps API编程计算长三角城市群2000—2009年的城市群分形维数,分析研究期内行政区划调整对城市群空间分布的向心性、均衡性和相关性的影响。2000年以来,长江三角洲城市群县级以上的行政区划调整变更主要包括市辖区内部调整和外部扩展,上海和南京作为长三角中心城市的地位因此不断增强,而杭州市的影响相对削弱;与此同时,长三角城市群的空间分布逐渐趋向均衡;此外,交通网络一体化增强了长三角城市群的空间联系与作用,推动了长三角的整体发展。Adminstrative regionalization adjustment will lead to spatial structure variation of urban agglomerations,and thus exert a significant impact on the development of regioanl urban system and economy.In this paper the Yangtze Delta was chosen as the study area and the related basic data was downloaded from National Fundamental Geographic Information System（NFGIS）.The software ArcGIS was employed to calculate the fractal dimensions of urban agglomerations in the Yangtze Dleta during the period from 2000 to 2009.Three kinds of fractal dimensions,namely,the aggregation dimension,the grid dimension and the spatial correlation dimension,were used to describe the spatial aggregation of urban agglomeration,the spatial equlibrium and the spatial interaction between urban agglomerations as well.The adminstrative regionalization adjustment in the Yangtze Delta included both the internal adjustment and the outwards expansion of municipal districts.The influence of Shanghai and Nanjing as the central cities has been strengthened while that of Hangzhou weakened.Urban agglomerations have been much more evenly distributed within the region as well.Integration of traffic network has promoted the spatial interaction of urban agglomerations and propelled the development of the region as a whole.
