 分析GIS与应用模型集成的研究现状及存在的问题。针对存在的问题,提出基于Web Services的GIS与应用模型集成方法。具体定义应用模型服务体系及其与空间信息服务体系的关系,讨论基于服务链的GIS-ervices与应用模型服务集成服务链样式、集成实现过程、集成开发流程,给出基于服务集成实现小流域地貌演化问题计算的服务集成分析设计与实验结果。实验结果证明本文提出的基于Web Services的GIS与应用模型集成方法正确可行。

The status and problems of the integration between GIS and GIS-based Model (GBModel) is analyzed.The method of integration between GIS and GBModel is proposed based on Web Services.GBM services architecture based on RM_-ODP and the relationship with OpenGIS s are analyzed.The integrated services train style,the integrated procedure and the developed flow are discussed between GBM services and GIS.Taking the Modern Catchment Geomorphic Evolution Model(MCGEM)as an example,the integration experiment is impleme...
