摘　　要：组件技术是当前GIS软件业的潮流。系统以安徽县域人口统计GIS为案例,基于.NET环境,将数据库技术、数学模型与GIS技术应用到人口统计信息管理当中,开发了重心模块、洛伦茨模块、人口金字塔模块与GM(1.1)人口预测等模块,完成了人口统计信息与地理空间信息的集成,实现了地图浏览、统计查询、专题制图、模型分析等功能。其强大的空间分析和可视化功能增强了人口统计信息的表现力,将进一步拓展人口统计GIS在相关领域的应用。The component developing technology is the tidal current of the GIS software industry. Based on the case study of the Counties＇ Population Statistic Geographic Information System in Anhui province, the system applies the relationship database technology, the mathematical model, the GIS technology to population statistic information management. Under the . NET framework, develops Gravitation module, Lorenz module, Population Pyramid module and module of GM（1,1） population foreeast. Thereby, it achieves the integration of the population statistic information and the geography spatial information, realizes the functions of map browsing, statistics inquiry, thematic mapping and model analysis, and enhances the population statistic inforrnation＇s expressiveness based on the powerful spatial analysis and the visualization functions, which will further promote more applications of population statistic GIS in the correlated domains.
