基于分形理论的长江中游城市群空间结构研究

Research on the Spatial Structure of the City Cluster in the Middle Yangtze River Based on the Fractal Theory

运用分形理论从城市空间分布的向心性、相关性及均衡性三个方面对长江中游城市群的空间结构进行研究。结果表明:长江中游城市群空间分布具有一定的集聚性,表现为从中心城市向周围城镇密度递减;长江中游城市群城镇的空间相关性较强,联系较紧密,长江中游城市群城镇空间分布总体上比较均衡。

It is indicated in the research,by use of the fractal theory,on the spatial structure of the city cluster in the middle Yangtze River from the centrality,relativity and uniformity of city space distribution that the distribution in the cluster is characteristics of the gathering that means the decrease of the density from central cities to ambient towns,and the space relativity of those towns in the cluster is stronger,the connection between is closer,and the space distribution of those towns is generally more equilibrate.
