摘要 空间决策支持系统的研发是当前GIS的一个重要方向。本文分析了空间决策支持系统当今所存在的一些问题,并将网格技术和OGSA架构引入到空间决策支持系统中,提出了基于网格服务的空间决策支持系统的结构框架。阐述了各组成部分的逻辑工作流程,并结合风暴潮领域的一个应用实例讨论了基于网格服务的空间决策支持系统的运行流程。最后分析并指出了基于网格服务的空间决策支持系统的优点。 The research of Spatial Decision Support System is an important branch of modem GIS. This paper analyzes some problems facing SDSS today by introducing grid technology and open grid services architecture into SDSS, puts forward the architecture of a grid service-based SDSS, then describes the functions and logics of all parts of the architecture in detail, and discusses the running proeess of the architecture by taking the applieation to the hurricane surge field as a case. Finally, it identifies the advantages of the grid service-based SDSS.
