运用分形模型，分析了江苏省城市体系的规模结构和空间结构。首位度指数表明，江苏城市体系规模分布已开始从首位型向序列型转变。Hausdorff分形维数表明，规模结构仍相对松散，首位城市仍具一定垄断性但已不是绝对垄断地位。空间关联维数表明，江苏城市体系具有明显的交通轴线分布特征。牛鸦维数比显示，江苏城市体系的交通网络通达性优良，各城市间联系较为紧密。集聚维数显示，江苏全省、南部区域、北部区域城市体系空间分布都呈集聚态；但南部区域已表现出一定程度的均匀分布格局，而北部区域的空间分布集聚程度却较高。在上述基础上，对江苏城市体系结枸的优化提出了建议。

By applying the fractal models, the paper analyzed the scale structure and spatial structure of Jiangsu＇ s urban system. Urban primacy indexes show the scale distribution of Jiangsu＇ s urban system began to transfer from the primary-city mode to the rank-scale mode. Hausdorff fractal dimension indicates the scale structure is still comparatively loose and the primary city of Nanjing is in fair monopoly but not in a position of absolute monopoly. According to the spatial correlation dimension, Jiangsu＇ s urban system is obviously distributed along traffic lines. The ratio of cow dimension to crow dimension explains Jiangsu＇ s urban system has excellent transport network accessibility and is in close contact. Three aggregation dimensions show the spatial distributions of the urban systems in Jiangsu Province, the south region of Jiangsu and the north region of Jiangsu are in aggregation, but the states of urban distribution in the south region of Jiangsu is in comparative quilibriumt while that in the north region of Jiangsu is in fairly aggregation. Based on these conclusions, the paper presents some suggestions to optimize the structure of Jiangsu＇ s urban system.
