Abstract: This article researches and explores urban agglomeration spatial organization from space structure and function, and also applies fractal theory to discuss Su-Xi-Chang urban agglomeration spatial organization. Through measuring and calculating the agglomeration dimension, gridding dimension and correlation dimension of Su-Xi-Chang urban agglomeration spatial organization, the result turns out that all elements of Su-Xi-Chang urban agglomeration have certain centrality centering Suzhou, Wuxi and Changzhou respectively. And also the elements possess the characteristic of equilibrium distribution and close relations. Then analyze the element function of the core cities, Suzhou, Wuxi and Changzhou using C-D function. On these grounds, it is obvious to discover the problems that the core city is not clear and leading function is not explicit.

摘要： 本文从空间结构和功能两方面运用分形理论对苏锡常城市群空间组织进行了研究。通过测算苏锡常城市群的集聚维数、网格维数和关联维数，结果表明苏锡常城市群空间组织各要素分别以苏州、无锡、常州三市为中心具有一定的向心性，分布均衡且相互关系密切。并结合C-D函数，分析苏州、无锡、常州三个核心城市的要素功能，发现苏锡常城市群空间组织的核心城市不明确，主导功能不清晰。
