结合农业地质环境调查的实际工作需要,设计了以MAPGIS和.NET为基础的农业地质环境信息系统,详细研究了系统实现过程中的海量数据组织与存储、图形数据加栽与显示、评价模型的实现与管理和软件网络结构模式等关键问题,而在此基础上开发实现了珠江三角洲农业地质与生态地球化学信息系统已成为珠江三角洲农业地质与生态地球化学调查评价的重要技术平台,也可以为其他类似GIS系统的建设提供参考或借鉴.%According to the demands of agro-geological environment survey,the agro-geological environment system based on MAPGIS and NET was designed. Several key problems were studied which would be considered in the development of AGEIS, such as organization and management of mass data, loading and show of graphical data, implementation and management of evaluation models and software network architecture. Finally, taking Pearl River Delta Economical Region as a case study area and based on the framework of AGEIS, authors develop Pearl River Delta Agro-geological and Eco-geochemical Information System (PAEIS) which played an important role in the agro-geological and eco-geochemical survey and evaluation in Pearl River Delta Economical Region, and also provided references to other similar GIS application system.
