【摘要】 从时间和空间两个尺度分析广西人口的空间分布特征,揭示广西人口的空间规律。文章基于2012年-2016年广西统计年鉴数据,借助QGIS、Arc GIS和GeoDa等软件,通过空间统计分析、意念地图、重心模型和空间自相关分析方法,分析广西108个县域人口空间分布特征和重心分布情况。结果表明:(1)2012-2016年广西男性、女性、非农业人口与常住人口的空间分布格局表现为由东南部和中部向西北部和北部逐渐减少。(2)2012-2016年广西男性、女性、非农业人口和常住人口的重心均位于几何中心的南部,表现为不均衡分布,南部的人口数量较多,为人口发展的重点区域。(3)2012-2016年广西男性、女性、常住人口和非农业人口的全局空间自相关系数值均为正值,表现为空间正相关,同时广西各县各类型人口存在较强的空间依赖性,并表现为空间聚集模式。(4)2012-2016年,广西人口分布的热点位于东南部,冷点位于西北部,区位差异明显。更多还原

【Abstract】 From the two scales of time and space, this paper analyzes the spatial distribution characteristics of the population of Guangxi’s and reveals the spatial laws of it. Based on the data of Guangxi Statistical Yearbook 2012-2016, this study analyzed the population distributions and migration trajectory of population gravity center in 108 counties of Guangxi by means of spatial statistical analysis, ideographic map, centroid model and spatial autocorrelation analysis using software such as QGIS, Arc GIS and Geo Da. The results show:(1) From 2012 to 2016, the spatial distribution pattern of male, female, non-agricultural population and permanent resident population in Guangxi gradually decreased from the southeast and central regions to the northwest and the north;(2) During 2012 to 2016, the population gravity centers of male, female, non-agricultural population and permanent population in Guangxi are all located in the southern part of the geometric center, showing an unbalanced distribution with a large population in the south where is a key area for population development;(3) The global spatial autocorrelation coefficient values of male, female, permanent population and non-agricultural population in Guangxi are positive during 2012-2016, showing a positive spatial correlation, and there is a strong spatial dependence of all types of population in Guangxi counties, at the same time, it shows space aggregation mode.(4) From 2012 to 2016, the hot spots of population distribution in Guangxi are located in the southeast, while the cold spots are located in the northwest with obvious differences in location.更多还原
