摘要
运用分形理论从等级规模和空间结构两方面分析了南通市城镇体系结构特征。研究结果表明,南通市城镇等级规模分形维数D为0.7731,小于1,这说明南通市城镇规模等级结构较为分散,属首位分布类型,城镇体系发育不成熟;城镇空间关联维数D′=1.2577,这表明南通市城镇相关程度较小,空间布局较分散;就如何优化南通市城镇体系结构提出了参考建议。
Using fractal theory, a analyzing of the hierarchical scale structure and the spatial distribution of Nantong city was done. The results show： I. The fractal dimension of size-scale structure（D） is 0.7731〈1,which indicates the size-scale structure is loose, and the law of the primate town is very big, so the urban system of Nantong city is not developed; Ⅱ. The fractal dimension of spatial distribution （D＇） is 1.2577,which shows the correlation of towns is weak, and the spatial distribution is dispersing. At the end of this paper, some advices for how to optimize the urban system of Nantong city were suggested.
