基于GIS邯郸市人口分布时空变化及影响因素分析

以邯郸市2010-2017年人口统计数据为研究对象,采用人口分布结构指数、人口重心、人口密度和空间自相关等分析方法,结合GIS技术、回归分析和Geoda软件分析了邯郸市年人口分布时空演变特征.结果显示:人口分布不均衡但态势逐渐减弱;人口重心位于邯山区和肥乡区交界处,偏离几何中心,呈由北向南移动;邯郸市人口密度地域差异明显,西低东高,符合邯郸市人口空间分布的密度模型为三次函数;人口呈现向邯郸市区集聚的趋势,大部分地区空间相关性较弱.邯郸市人口时空变化主要受城市规划和政策等因素影响.

Spatial-temporal Evolution and Influencing Factors of Population Distribution in Handan City Base on GIS

Select the population statistical data from 2010 to 2017 in Handan city as the research object. Analyses the spatial-temporal evolution characteristics discussed with the index of population distribution structure, gravity center of population, population density and spatial autocorrelation methods, combined with GIS, Geoda and regression analysis. The results show that the population distribution is not balanced, but the situation is gradually weakened; The population gravity center is located at the junction of Handan District and Feixiang District, which deviates from the geometric center and moves from north to south; The regional difference of population density of Handan city is obvious, which is lower in the west and higher in the east, and the population distribution density model conforming to cubic function; The population gathers to the urban area, but the spatial correlation of many places is weak. The temporal and spatial evolution of population in Handan city is mainly influenced by the city planning and policy.
