摘　　要： 设计了地理模型的语义表达方法,提出了基于Web Services的地理模型分布式共享方案。定义了地理模型服务及其发布、查找和重用的体系结构,设计了地理模型服务的功能体系。最后,构建地理模型共享门户作为验证平台。实验表明,基于Web Services的地理模型分布式共享方案可以实现网络环境下异构地理模型的有效利用和充分共享。 The realization of distributed geographic models sharing may strengthen the functions of GIS analysis, forecasting, decision-making and so on. But the existing distributed geography model resources have not yet realized global sharing. With the rapid development of information technology, the geographic model sharing via Internet has become not only possible, but also essential. We analyzed the present situation and existing problems in geographic models sharing and introduced a new method for distributed geographic models sharing based on Web Services, which is provided to locate, share, and publish model sources. We also defined Web Services for geographic models and its corresponding service framework, and service system in order to overcome the obstacles of model resources derived from the distributed environment. We constructed geographic models sharing gateway as a confirming platform. Experiments proved that the method for distributed geographic models sharing proposed here is practical and feasible based on Web Services. A user can locate, access, and retrieve all geographic models available in the architecture in an easy, flexible, and agile way through Web Services.
