山西省人口分布空间格局演变及成因分析

Evolution and Formation Factors of Population Distribution Spatial Pattern in Shanxi Province

根据2005—2016年山西省人口分布状况,运用人口密度、基尼系数、洛伦兹曲线以及标准差椭圆的方法,分析山西省人口分布空间格局演变的特征,并揭示影响人口分布的因素。结果表明:山西省人口分布特征地区差异显著,空间分布格局受自然因素、经济因素和政策因素的相互影响;从市域尺度看,太原市始终是人口密度最大的地市。总体而言,人口密度大约为100~200人/平方千米,处于一般过渡区;人口密度的基尼系数大于0.40,洛伦兹曲线中人口分布偏离均匀分布的程度加大,不均匀现象显著;人口重心位于平遥县,2005—2016年,人口重心总体呈现出向东北方向移动的趋势。

Based on distribution of population in Shanxi Province from 2005 to 2016, the characteristics of population distribution spatial pattern evolution in Shanxi Province were analyzed with population density, Gini coefficient, Lorenz curve and standard deviation ellipse, and the factors influencing population distribution were revealed. The results show that the geographical distribution of population in Shanxi Province is significant, and the spatial distribution pattern is influenced by natural factors, economic factors, and policy factors. From a municipal scale, Taiyuan is the city with the largest population density. In general, the population density is about 100~200 person/km2, which is in the general transitional area; the Gini coefficient of population density more than 0.40, the distribution of the population distribution in the Lorenz curve deviates from even distribution, and the unevenness is significant; population center of gravity located in Pingyao from 2005 to 2016, the population center of gravity showed a trend of moving to the northeast.
