摘　　要：在GIS技术支持下,建立安徽省人口地理数据库,使用密度分析法、重心分析法和空间自相关分析法对安徽省1990—2012年人口时空分布特征进行了分析。结果显示,全省人口密度总体上呈由北向南递减分布格局,皖北地区人口密度呈增加趋势,皖南人口密度相对稳定,人口重心位于几何重心的西北方向,20年来人口重心从长丰县沿西北方向移动到寿县境内。全省各县(市)人口密度存在空间正相关性,且随时间推移逐渐减弱。Establishing the geographic database of population in Anhui Province supported by GIS,and the spatial and temporal distribution characteristics in Anhui population were analyzed bewteen 1990 and 2012 based on density analysis,weight analysis and spatial autocorrelation analysis. The results showed： ①Population density of northern Anhui increased,meanwhile,the southern Anhui remained stable since 1990. The characteristic of population distribution in Anhui Province was dense in the north and sparse in the south; ②The population gravity center was located in the northwest of the geometry gravity center,population gravity center moved to Shouxian County from Changfeng County toward the northwest direction in the past 20 years; ③There was certain spatial correlation of county population distribution in Anhui. That was similar areas cluster in the space,and this trend would gradually diminish over time.
