长江流域城市人口分布及空间相关性研究

本文选取长江流域104个城市人口样本作为研究对象,采用人口分布的结构指数和空间自相关分析方法,以及借用GIS技术来研究长江流域城市人口分布的空间动态特征和城市人口之间的功能联系。结果表明,长江流域城市人口空间结构呈均衡发展态势;人口密度分布呈现趋同趋势;城市人口与邻近城市人口之间的空间正相关要多于空间负相关;长江流域城市人口之间的空间关联性被分为八种类型。

A Study on Urban Population Distribution and Spatial Auto-correlation in Yangtze Basin

With data collected in 104 cities along Yangtze River Basin,by using population structure indexes,spatial auto-correlation analysis and GIS technology,this paper looks at the special features of urban population distribution in Yangtze River Basin and the relationship among urban population in different cities.The results show that(1) urban population spatial structure in Yangtze River Basin presents the equilibrium development situation;(2) the population density distribution presents converging trend;(3)There are more spatial positive correlation than negative correlation between them,and urban population spatial correlation in Yangtze River Basin is divided in 8 types.
