摘要
介绍了在国家级人口地理信息系统中 ,利用 2 0 0 0年人口普查信息 ,采用三维模型显示、罗伦斯曲线、人口重心和人口潜力等方法 ,宏观分析了中国人口分布的特征。并在城市人口地理信息系统的基础上 ,通过对城市零售单位布局的分析 。
Based on the 2000 population data from Population Census in China, The Population Geographic Information Systems at national and city level are established. The methods to manage and analyze the population data in E Government are presented. In nationwide approach, the characteristic of spatial distribution of population in China is analyzed, by the methods of 3 D model display, Laurence curve creation, movement of population center of gravity in different periods and population potential. The paper then discusses the application in the field of location distribution of retailing system in city level,consistent with population distribution and location of retailing unit and affecting area of retailing units. And the model to locate the retailing unit is proposed.
