A spatial analysis and decision-making system was developed for data describing the water condition in various regions to improve the management of water quality,quantity,environmental capacity,regional distribution,and pollution source.The system uses the GIS(geographic information system) and database management.Spatial data management,the attribute data management,and the relational database management are integrated into the spatial analysis and decision-making.New,high quality data is imported into the attribute database to dynamically renew the database.The data is visualized using a thematic map rendering method.Thus,the system provides the basis for synthetic management and planning of regional water environments.
