山东省城市规模结构及其分形特征

选取1986,1991,1996,2001和2006年山东省17个地级市城市人口规模的资料,运用城市首位律、城市金字塔理论及位序-规模法则分析了山东省城市人口规模的变化,继而运用分形理论阐释了位序-规模曲线.结果显示,首位城市济南人口规模尚有可观的发展潜力,山东省城市体系属于典型的＂双核心＂结构;城市规模结构已从传统＂金字塔形＂向＂纺锤形＂转变;城市规模由分散趋于集中,人口分布趋向均衡,城市体系发育日益成熟;分形特征明显.

Urban Size Structure and Fractal Characteristics of Shandong Province

According to the population data of 17 major cities in Shandong province of 1986,1991,1996,2001 and 2006,this paper analyzed changes urban population size using the primacy law,the urban pyramide and the rank-size law,then the rank-size curves were explained by the theory of fractal.The results show that the primate city Jinan had considerable potential to development,the urban system of Shandong province belong to the typical"dual-core"structure;the population size structure has changed from ‘pyramid'model into that of‘spindle';the urban size distribution tended to concentrate;the population distribution tended to equilibrium;the urban system developed maturity increasingly;the fractal characteristic is obvious.
