河南省城市体系等级结构变化的分维分析

An Analysis of Fractal Dimensions of Hierarchical Structure change of the Urban System in Henan Province

本文借助分维及城市规模分布的离散度和均衡度指数分析了河南省城市体系等级结构演化的动态特征，并利用Ｒ／Ｓ分析考察了其发展趋势，发现系统的要素规模差异逐渐缩小而且具有持久性，这表明河南省城市的人口分布将逐渐趋于均衡，需要采取优化措施。

A preliminary study was made in the paper on hierarchy of the urban system in Henan province.The fractal property has degenerated to some extent and the value of fractal dimension. Namely,the Pareto coefficient (or exponent) has been gradual increasing,which maybe caused mainly by the strategy of urban development presented in China in 1980s,and,in the end,it was pointed out that the hierarchical structure of the system of cities must be improved with fractal idea.
