山西省人口空间分异格局研究

Differentiation of Population Spatial Distribution in Shanxi Province

人口分布是人口发展过程中自然、社会、经济、文化、历史等多种因素综合作用的产物,这些因素通过影响人口的自然增长和机械增长,不断塑造着人口分布的格局.本文基于第六次乡镇级人口普查数据,利用ArcGIS 10.3可视化山西省人口信息的空间分布格局,通过计算Moran’s I指数、G统计量、信息熵等空间分异指标,结合地形、经济、资源、产业等特征,得出山西省各人口要素空间分异特征,发现山西省各项人口指标空间自相关性显著且人口分布受矿产资源导向和经济因素影响显著,并针对出现的问题给出政策建议.

Population distribution is the result of the comprehensive action of natural,social,economic,cultural,historical and other factors in the process of population development.Those factors constantly shape and change the pattern of population distribution through influencing the natural and mechanical growth of population.Based on the Sixth Census Data of China at township-level region,used ArcGIS 10.3 to visualize the spatial distribution pattern of population information in Shanxi province,the mechanism of population spatial differentiation was studied by using Moran’s I index,G statistics,information entropyand other spatial differentiation indexes,and according to the characteristics of topographic features,economy,resources and industries in different region,the following conclusions were got:the spatial differentiation characteristics of population factorsin Shanxi Province.Meanwhile it is found that the spatial autocorrelation of population indexes in Shanxi Province is significant and the population distribution is significantly influenced by resource orientation and economic factors,and some policy suggestions are given to solve the problems that have been..
