山西中部城镇群等级规模分布研究

Research of the Hierarchical Size Structure of Central Urban Agglomeration of Shanxi Province

运用城市人口规模的位序-规模法则、首位比、分形维数等方法,对2001年以来山西中部城镇群城市规模分布的类型、特征进行了鉴别,并与武汉城市圈、中原城市群、长株潭城市群的等级规模结构进行区际比较.研究表明,山西中部城镇群规模分布符合分形特征,城市体系呈首位分布,城市等级差异虽然有缓慢减小趋势,但距离最优状态还有很大差距;与我国中部其他城市群比较,山西中部城镇群结构相对松散,首位度和首位比较低,尚未形成等级规模合理的城镇群体系.

This paper studies the hierarchical size structure and character of central urban agglomeration of Shanxi Province in recent yeans,using Rank-size Rule,Law of the Primate City,the Fractal Dimensions making inter-dirstrit comparison with urban agglomeration of Wuhan,Zhongyuan and Changzhutan.The results indicate that,the hierarchical size structure of central urban agglomeration of Shanxi Province fits to fractal character.The system of urban agglomeration keeps the distribution of the primate.City-size differences are shrinking slowly,but there is a long way to the best state;compared with the rest cities of the Mid-west of China,the hierarchical size structure of central urban agglomeration of Shanxi province is comparatively loose,law of the primate comparatively low,not developing into the system of urban of the formal city-size yet.
