成渝都市群城市体系规模分布的实证研究

Chengyu Megalopolis Urban System Dimensions Distribution of Empirical Research

本文依据分形理论,采用1990—2008年成渝都市群各等级城市非农业人口时间序列样本数据,研究了成渝都市群城市体系规模分布的分形特征。经验分析表明,成渝都市群城市体系规模分布基本满足城市"位序—规模"分布规律并具有分形特征,首位城市垄断地位不强,特大城市断层,大城市数量不足,中小城市发育程度较高。最后,本文据此提出了发展和完善成渝都市群城市体系的对策。

Based on the fractal theory,the paper analyses and investigates the urban system dimensions distribution using urban non-agricultural population data of Chengyu megalopolis adopted 1990~2008.Empirical analysis demonstrates the urban system dimensions distribution of Chengyu megalopolis meets the city distributing rules ＂sequence-scale＂ and the fractal characteristics,but the primate city monopoly position is not strong,extra large city faulting,large cities are not sufficient,small and medium-sized city development level is higher.Finally,this paper puts forward the countermeasures of developing and perfecting the urban system dimensions distribution of Chengyu Urban group.
