In order to provide scientific and easy used decision method, increasing the degree of decision, aiding people to manage and decide, many managing departments have developed the DSS (Decision Support System) in some degree. However, as the development of technology and application, the present DSS has not already adapted to the departments which have many spatial problems to solve. SDSS, the tendency of GIS and DSS' integrity, is now emphasized more and more worldly. But, to this system, there have many different opinions. At the same time, there are not system report about SDSS applied in Water Environment Decision Support.In accordance with the present situation, this paper presents some research, which will focus on the following issues:1. Inquiring into the form and development about SDSS, put forwardthe three method of integrating GIS and DSS into SDSS. Aftercomparing the three methods it put forward a structure of SDSS basedon GIS;2. Discuss the importance of the Visualization in Scientific Computing used in developing Man-machine Interactive System. Deeply research the Visualization in Scientific Computing, and apply it into the GUI and Man-machine Interactive Interface, put forward a scheme of Man-machine Interactive System which based on visualization;3. Inquire into the organization pattern of spatial data and attribute data, give out the logical and physical designing structure. Provide the total structure of Spatial Database Management System, and inquire into the connection of spatial data and attribute data;4. In accordance with the present situation of model's management, inquire into the type and its explain. On basis of it, it analyst the organization and storage of Model Base, give out the Model Base Management System based on the Relation Database Management System;5. Based on the above pattern, it designs and develops the Three Gorge Water Environment Spatial Decision Support System (SDSS), giving a new scheme to protect water environment.
