Based on an analysis of objectives of developing Pearl River Delta agro-geological and eco-geochemical survey and evaluation information system （PAESEIS） and following the theories of software engineering and object-oriented methods, this paper generally designs its structure and functions, then develops the system based on MAPGIS 7.0 and Microsoft .NET, and finally focuses on several key problems such as organization and storage of data, loading and display of GIS data as well as implementation of evaluating models. PAESEIS is aimed to give a reference for other similar GIS application systems.
