智能化空间决策支持模型库及其支持下GIS与应用分析模型的集成

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

通过对模型库及模型库支持下 GIS与应用分析模型集成方式的探讨 ,以及其它 GIS与应用分析模型集成方式的对比 ,作者指出模型库方式将是 GIS与应用分析模型集成的主流方向 ,提出了一种新的 GIS与应用分析模型集成的框架 :知识驱动的空间决策支持模型库体系 ,它将数据库、模型库和知识库技术三库合一融入到 GIS中 ,实现 GIS与应用分析模型的无缝集成 ,以进一步提高 GIS对复杂空间决策问题的决策能力。从服务于模型库的知识库建设、智能化模型库支持下的决策流程等方面进行剖析 ,展现了知识驱动的空间决策支持模型库支持下 ,GIS与应用分析模型集成的优越性、先进性。通过应用实例验证了知识驱动的空间决策支持模型库体系支持下 。

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.
