Study on Intelligent Spatial Decision Support Model Base System and Model Integration in GIS

This paper makes an analysis on model base and the integration method of GIS and application models based on model base. After making a comparison on the integration method of model base with other old integration methods, the authors bring up a new scheme on integration of GIS and application models: spatial decision support model base system driven by intelligence. The new system is supported by data base, model base and knowledge base technique. The paper makes an analysis from how to build knowledge base serving model base, the decision flowsupported by intelligent model base and so on. It also gives an instance of basin environment pollution management based on intelligent model base system, which validates the feasibility and validity of the new model integration method.
