新疆人口与经济空间分布特征分析——以南疆三地州24个县(市)为例

An ESDA-GIS Analysis of the Temporal and Spatial Distribution of Population and Economy in Xinjiang—The Three Prefectures in Southern Xinjiang as an example

文中选取新疆(南疆)三地州2008年和2014年各县(市)的人口与GDP数据,运用地理集中度、耦合(不一致)指数和空间自相关等分析手段,结合地理信息软件,对整个三地州24个县(市)人口与经济的分布的不均衡性,进行空间格局演变的分析。最终得出以下结论:(1)三地州的人口地理集中度与经济地理集中度的偏差性巨大,二者的相关性不强;(2)人口集聚的速度快于经济集聚的速度;(3)经过7年的变化,人口与经济耦合(不一致)类型趋向于二者协同发展的类型,并且大致呈"T"形分布;(4)2008年与2014年人口与经济不一致性的空间全局Moran指数的Z检验结果,由不显著变为显著;(5)局域空间集聚的"H—H"型区域增多,"L—L"型区域向"H—L"型区域转化。

Selecting the 2008-2014 population and GDP data of the three prefectures in southern Xinjiang, this paper analyzed the changes of the spatial distribution of the imbalanced population and economy in light of the geographic concentration, coupling(inconsistent) index and spatial autocorrelation analysis by the application of Arc GIS10.2 and Geoda software. It found that(1) Population geography centralization deviates largely from economic geographic concentration, and the correlation is weak.(2) The population gathering is faster than the economic agglomeration.(3) After 7 years of changes, the population and economic coupling(inconsistent) tends to be collaborative, roughly in a T shape distribution.(4) From 2008 to 2014, the Z test of the global Moran index shows a significant change from an insignificant one in terms of the population and economic inconsistency.(5) The local spatial agglomeration of H-H region increases, and the L-L region moves to H-L region.
