英文摘要：

In order to solve the problem in the management system is designed for sewage outfall information management of sewage outfalls, an information based on the WebGIS technology. The architecture design and principle of the system are elaborated and implemented. The presented system possesses the following functions： basic GIS operation, interactive information display of outfalls, GIS mapping and measurement, loading the maps of environmental and marine functional areas, management of thematic maps, charting, spatial query and positioning, map printing, as well as management of the legal document library. The system can simplify the outfall information managing process, provide reference information for the environmental protection agencies with the means of information technology, assist decision-making for ouffall management, and thus improve the efficiency of management affairs.
