摘　　要：基于网格的智能信息服务是地理信息系统发展的一种新模式。从分析地理信息系统面临的挑战出发,剖析了基于网格的智能信息服务出现的必然性。介绍了空间信息智能服务的概念以及网格与空间信息智能服务的关系;设计了一种由数据服务节点、功能服务节点、管理节点和门户节点组成的网格空间信息智能服务框架;提出了实现基于网格的空间信息智能服务所涉及的空间数据服务生成、数据服务封装、服务注册、服务组合与工作流建模等关键技术。最后,基于Microsoft VisualStudio2005进行了实验。Spatial information intelligence service based on grid is a new pattern of GIS. In terms of the analysis of challenges to GIS, the inevitability was discussed that spatial information intelligence service based on grid e--merged. The concepts relating to spatial information intelligence service and relationship between gird and spatial information intelligence service were introduced. A framework of spatial information intelligence service based on grid was designed, which was composed of data service node, processing service node, administration node and portal node. The key technologies to achieve it were put forward, such as spatial data service create, data service package, service register, service composition and workflow modeling. A prototype system was developed based on Microsoft VisualStudio2005 to verify the design.
