中原经济区城市体系等级规模结构分析

The Analysis on the Scale Level Structure of City System in Zhongyuan Economic Region

城市等级规模结构揭示了一区域内城镇规模的分布规律,是城市体系研究的重要内容。运用城市首位律、分形理论、城市规模基尼系数对中原经济区29座城市的等级规模结构进行分析,结果表明,中原经济区的城市体系等级规模结构不尽合理,城市首位度偏低,缺乏首位城市、中等城市发育。优化城市等级规模结构应加快中原城市群发展,突出核心城市的带动作用;增强城镇承载能力,完善发展轴线;提高以城带乡发展水平,激发节点发展潜力;扎实推进新农村建设,为周边对接创造良好环境。

City scale structure＇ reveals the rule of the distribution of urban rank-size in an area. It is a very important part of the study of city system. Thispaper applies the urban primacy index fractal theory and City nicky coefficient on the urban rank-size structure of 29 cities in the Zhongyuan economic zone. The results show that the level of scale structure in the city system, of Zhongyuan economic zone is not reasonable, the city＇s first degree is too low, and it lacks the development of the Primate City and medium-sized city. Accordingly, the paper puts forward some related measurements to optimize Urban rank-size structure.
