| 摘 要： | 利用分形理论中的聚集分维和网格分维计算长江三角洲、珠江三角洲和东京圈城市体系的空间结构维数．并分析其分形结构特征。结果表明，东京圈呈现内部空间结构的紧致性；长江三角洲城市空间亦趋于集聚和整合；珠江三角洲城市体系空间结构最为松散。据此提出长江三角洲和珠江三角洲要发展卫星城，构建广域交通体系．扩大城市容量，增强各二级中心集聚、辐射能力等改善措施。

| Abstract: | While Tokyo megalopolis, the Changjiang Delta and the Zhujiang Delta are taken as centers respectively in Asia, the spatial structures of the urban systems are studied by using aggregation dimension and grid dimension of fractal theory. The characters of the three spatial patterns of the urban systems are discussed. It is shown that the spatial structure of Tokyo megalopolis is tight, that of the Changjiang Delta is of more and more centrality and conformity, and that of the Zhujiang Delta is much looser than the others as the economic activities have been fastened around the Zhujiang estuary. It is suggested that residential towns and extensive traffic systems should be constructed and urban capacity be expanded to improve the urban systems in the Changjiang and Zhujiang Deltas. |
