为定量研究市域尺度上的聚落体系的分形特征，以ArcGIS9．3软件为平台，选取江苏镇江地区团聚状聚落体系为研究对象，通过计算豪斯道夫维数分析了聚落体系规模分布的分形特征，通过计算关联维数和集聚维数，从聚落要素的空间相关性和聚落随机集聚的向心性两方面，分析了聚落体系空间结构的分形特征，对聚落体系的空间集聚性的多级分形特征作了重点探讨。结果表明：镇江地区团聚状聚落体系在规模分布和空间结构上都具有比较明显的分形特征，表现出自相似结构；镇江地区团聚状聚落体系的空间集聚性存在多级分形的特征，中心村的空间集聚能力强于城市和镇；地形和聚落体系的发育程度是影响聚落体系的空间集聚性主要原因。因此，在以后的工作中可以利用分形思想进行聚落体系规划，有效地利用地理空间资源。

英文摘要：

Fractal study is one of the most important content in modern theoretic geography. This paper commenced with the application of the fractal theory and tried to find the rule of the settlements system of Zhenjiang in Jiangsu Province at the scale of the municipal area,by using ArcGIS9.3 software. Based on the fractal theory,the paper analyzed the scale structure and spatial structure of settlements system,and found out that the settlements system had the fractal properties. Thus, the fractal theory could be suitable for cal- culating and analyzing the scale structure and spatial structure of reunion-like settlements system in the district. According to the results of calculation and analysis,the paper drew the conclusions below. （1）Re- union-like settlements system in Zhenjiang were fractal in the scale structure and spatial structure of settle- ments system,acting as a self-similar structure. In the settlement system,the spatial correlation among the city,town and centre village was strong,indicating that the evolution of self-organization in spatial struc- ture showed optimization trends. The factor of the settlements system in the study area distributed evenly from the center to the periphery. Therefore, fractal theory would be important for the planning of settle- ments system and be valuable in practice. （2）The spatial aggregation of reunion-like settlements system in Zhenjiang acted as multi-level fractal character. The spatial aggregation city-town-centre village-nature vil- lage, town-centre village-nature village and centre village-nature village settlement system were different in some places. In most place,such as around the center of Zhenjiang city and in the hinterland of Jurong,the spatial aggregation of centre village was stronger than that of the city and town. In the hinterland of Da- gang New District, the spatial aggregation of town was the strongest. Therefore, we can conclude that the fractal distribution would be affected by the degree of development of the settlements system. All in a
