河南省城市体系规模结构演变分析

Analysis of Evolution of City-size Structure of Urban System in Henan Province

利用1988—2012年城市非农人口数据,运用城市首位度指数、位序-规模法则、城市基尼指数等方法分析了河南省城市体系规模结构的演变。研究结果表明:河南省城市体系规模结构合理;城市规模结构符合位序-规模法则,各等级城市规模稳步增长,呈现竞争激烈的发展态势;城市体系规模结构属首位分布和位序-规模分布的过渡类型,首位城市郑州有相当大的发展空间,第二、第三位城市(洛阳、商丘)实际规模与理论规模也有差距。今后应加快交通网络建设,分类指导,重点促进首位城市郑州的产业升级和现代服务业发展,完善县城基础设施建设,形成城市体系发展的拉力和推力,进一步促进河南省城市体系规模结构优化。

The paper collected the data of urban non-agricultural population for each city in Henan Province from 1998 to 2012,and analyzed the evolution of city-size structure of urban system by using city primacy index,rank-size rule and city Gini index. The results show that,the structure of urban system in Henan Province is rational. City-size structure in Henan Province is consistent with rank-size rule,each city is mounting up steadily and marked by the development of＂try to overtake each other＂. City-size structure is transitional type between primacy distribution and rank-size distribution. Zhengzhou,the primacy city of Henan Province,has sizable space for development. The size of the second city and the third city（ Luoyang and Shangqiu） are also different from their theoretic size. Finally,some suggestions are presented,such as constructing traffic network rapidly,offering specific guidance for different cities,promoting upgrade of industry and development of modern service trade in Zhengzhou,perfecting infrastructure of counties,thereby forming development drag and thrust of urban system to promote whole rise of city-size structure of urban system in Henan Province.
