摘　　要：采用人口重心模型,在GIS技术支持下着重对1989—2005年山东省人口重心迁移特征进行了研究,并在此基础上分析人口重心迁移的主要影响因素。结果显示,山东省人口重心接近几何中心,人口重心自东北向西南方向迁移的趋势明显,其移动轨迹呈现出一定的曲折和波动。山东省人口重心迁移受自然、社会经济和政策等多种因素的影响。Using population gravity center model and GIS technology,this pater made emphases on the study of the characteristics of the migration of population gravity center from 1989 to 2005 in Shandong Province.And based on it,the influence factors of the moving of the population gravity center were analyzed. The results showed that the population gravity center approached the geometry center in Shandong Province, the trend that population gravity center move from northeast to southwest was obvious,and the migration orbit of population gravity center demonstrated certain fluctuation. The migration of population gravity center in Shandong Province was mainly affected by many factors such as nature, socio - economic factor and policy, etc.
