摘　　要：都市连绵区的边界界定对象包括两个方面,都市连绵区的整体空间范围边界界定和内部结构边界界定。对长江三角洲及其周边地区所有的238个县、市、区的就业人口结构和空间分布特征进行主成分分析和聚类分析,探讨相应都市区的结构特征以及都市区的空间组合特征等,进而确定了长江三角洲地区的整体范围边界和内部结构边界。其结论包括①长三角都市连绵区的整体空间范围包括苏州、无锡、宁波的全部以及上海、南京、常州、杭州、镇江、扬州、泰州、南通和绍兴、舟山的部分县市区;②长三角的内部结构可分为三大部分,以上海为中心的环太湖城镇密集区,以南京为中心形成沿长江城镇区,以杭州、宁波为中心形成环杭州湾城镇密集区,其内部边界界线分别以镇江丹徒区、嘉兴—湖州为边界地带。从核心城市上海角度看,整个长江三角洲都市连绵区的内部结构呈现“圈层推进+轴线延伸”的空间特征。The Boundary analysis of megalopolis contains mainly the whole spatial boundaries and the inter- nal structure boundaries. With the methods of principal component analysis and the cluster analysis, 238 counties, cities and districts in the Yangtze areas were explored of the structure features and spatial organi- zations of metropolis. Then the above two kinds of boundaries of the megalopolis is analyzed. The findings include, first, the whole spatial boundaries of the Yangtze Delta Region containing Suzhou, Wuxi, Ning- bo, and Parts of Shanghai, Nanjing, Changzhou, Hangzhou, Zhenjiang, Yangzhou, Taizhou, Nantong, Shaoxing, Zhoushan. The second is that the megalopolis could be divided into three parts, the Huan-Taihu Lake Regions with the core city of Shanghai, the Yangtze River Regions with the core city of Nanjing and the Hangzhou Bay Regions with the core city of Hangzhou and Ningbo. And the internal structure bounda- ries are locate at Dantu and Jiaxing-Huzhou. With the perspectives of Shanghai, the internal structures of the Yangtze Delta Regions have features of consenters and axes characters.
