基于ArcGIS的菏泽市人口重心迁移研究

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。

Study of the Migration of Population Gravity Center in Heze City Based on ArcGIS

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.
