In order to realize the target sharing of lake information resources, Browser/Server framework was adopted, ArcIMS acted as publisher of maps on internet, advanced ASP technique combined, and lake database on internet developed. Lake information resources include physical, chemical and biological characteristics of lakes, as well as maps, remote sensing images, scenery pictures, etc. There are basic management and spatial analysis functions to lake database in the lake information system based on WebGIS. They are mainly: editing and updating spatial and none-spatial data, searching and inquiring information, displaying, zooming in, zooming out, and roaming of vector data, buffer analyzing and thematic mapping, and so on.

Key words: lake, database, WebGIS, information sharing
