The authors designed the structure, functions and database of the Yongjiang River Basin Water Environment Management Information System (YRBWEMIS) through the integration of ArcGIS Engine software with VC. The spatial data and attribute data in the YRBWEMIS are stored and managed separately. The system functions include display, query, statistics, spatial analysis and thematic mapping for water pollution sources, water quality, water function regionalization and catchments region.展开更多
