Study of Application Models of Aquatic Environment Spatial Decision System

As the integration of the geographic information system and the decision support system,the decision support system incorporates the advantages of the two.Introducing the spatial decision support technologies into the aquatic environment computation,the paper discusses how to integrate the aquatic environment prediction model,decision analysis approaches with spatial analysis technologies and makes analysis of the structure of the aquatic environment spatial decision model and the process of establishment.The properties of the application model(the emergent water pollution system) are elaborated with cases and relevant constructive conclusions are finally made.
