基于ArcGIS的菏泽市人口重心迁移研究

摘要

Through the population gravity center model theory, the population gravity center migration trajectory in Heze during 2003-2012 was obtained using GIS technology, the population gravity center migration laws were studied, and the main influencing factors were analyzed. The research showed that, Heze`s population gravity center was closed to geometric center;the migration of total population gravity center was related to non-agricultural population gravity center, male gravity center and female gravity center, the migration trends were similar;the trend of the gravity center from southeast to northwest migration was obvious;the migration of population gravity center was affected by many factors, such as population migration, natural population growth rate, social economy in Heze City.%通过重心模型相关理论，借助ArcGIS软件技术绘制2003～2012年菏泽市人口重心迁移轨迹，研究人口重心迁移规律，并分析影响其移动的主要因素。研究表明，菏泽市人口重心与菏泽市几何中心相接近；菏泽市总人口的人口重心迁移与菏泽市非农业人口重心、男性人口重心、女性人口重心具有关联性，移动趋势相近；菏泽市人口重心迁移的总趋势是由东南向西北方向移动；人口重心迁移受人口的迁入迁出、人口的自然增长率、菏泽市的社会经济状况等多种因素影响。
