分布式水文模型与网络GIS技术集成的研究

摘要

Distributed hydrological model is currently the hotspot of watershed model research. In this research, the data storage, physical realization and message communication of distributed hydrological model in Web-based GIS-framework are discussed through integrating distributed hydrological model with Web-based GIS technology. A com-plete scheme of integrating distributed hydrological model with Web-based GIS is designed, based on which the net-work computing service of CREST ( Coupled Routing and Excess Storage) model is accomplished. The results sug-gest that the integration of distributed hydrological model and Web-based GIS technology expands the scope of the application of distributed hydrological model.%分布式水文模型是目前流域模型方面的研究热点.为此,将分布式水文模型与网络GIS技术相集成,探讨了分布式水文模型在网络GIS框架下的数据存储、物理实现和消息通信方式,设计了完整的分布式水文模型与网络GIS框架集成方案,并根据集成方案实现了CREST模型的网络计算服务实例.实例结果表明,分布式水文模型与网络GIS技术集成具有良好的应用效果,能够拓展分布式水文模型的应用范围.
