摘　　要：通过研究并实现空间信息服务平台,以解决数据共享和应用功能共享为主要目标。在数据共享上,采用了基于空间数据库的索引技术及基于地理标记语言(GML)的数据交换技术;在应用服务上,采用基于Web服务的服务功能开发技术,从而满足空间信息应用(Web、桌面系统及移动终端)的数据和功能需求。重点论述了基于R树索引技术进行空间数据的存储和检索,实现空间数据的快速检索,采用基于Web服务技术,实现空间信息应用功能共享,从而支持空间数据查询、获取及空间分析功能。最后以一个典型的土地规划应用为例,测试并论证了基于R树索引及空间信息服务技术的有效性。In this paper, by implementing the spatial information service platform, the data sharing and application functions sharing were regarded as the main targets. On the data sharing, index technology based on spatial database and the data exchange technology based on Geographical Markup Language（ GML） were used; on the application service, the service function development technology based on Web service was used to satisfy the spatial information application（ Web, desktop and mobile terminal） data and functional requirements. R tree index technology was emphasized for spatial data storage and retrieval, and rapid retrieval of spatial data based on Web service technology was achieved. The sharing of spatial information application functionality was realized to support spatial data query and spatial analysis. Finally, a typical application of land use planning use taken as an example, to test and demonstrate the effectiveness of the spatial information service technology based on R tree index.
