摘要
文章通过测算安徽省近20年来城市体系规模分布的分维值,对该省城市体系规模现状及演化进行了具体分析,得出以下结论:现今安徽省城市规模分布较集中,人口分布呈现低水平均衡状态;1988年以来,就城市体系规模结构的演化特点来看可分为两个阶段:1988年—1999年,城市规模分布趋于集中;而进入2000年以来,城市规模分布趋于分散。并分析了这种现状及演化的原因,提出若干优化城市体系和促进经济发展的建议。
Based on the fractal theory, the actuality and evolvement of size distribution of urban system in Anhui Province are made a thorough analysis.The result shows that the size distribution is centralized,and population distribution is balanced at present.Since 1988,It can be divided into two phases based on the evolvement characteristics of size distribution of urban system：from1988 to 1999,the size distribution is concentrating continuously;On the contrary, it is on decentralization since 2000.This paper analyzes the cause of this evolvement phenomena and put forward some suggestion to optimize the structure of urban system and promote economic development.
