摘　　要：地理空间信息技术(WebGIS)的飞速发展,给水土保持信息监测和管理提供了新的手段和方法。为有效管理水土保持信息,在对水土保持信息的数据库设计和数据组织、关键功能设计等的基础上建立了一个基于B/S的水土保持信息查询系统,系统采用Oracle+ArcSDE+ArcIMS体系构架实现了空间数据的五类查询方式:位置查询、条件查询、名称查询、空间关系查询、模糊查询;特别地设计和实现了地面监测数据的双向查询功能。水土保持决策管理者通过网络可以对各种模型方法估算的水土流失结果进行定量评价和专题统计分析,极大地提高了管理决策的科学性和准确性。The development of geographical spatial information techniques, especially WebGIS, bring the advance method for soil and water information monitoring and management. To manage soil erosion information in Miyun reservoir area, a query information system based on Browser/Server was developed through database design, data organization and key function design. The architecture of integrating of Oracle, AreSDE, ArclMS was adopted in the system. Five types query of spatial data, that is, location query, conditional query, name query, spatial relationship query, fuzzy query were implemented in the application. Especially, monitoring data of bidirectional query between spatial and attribute data was designed and implemented. The decision-making officers can analyze and evaluate soil erosion results more effectively and conveniently via the Internet, which improve the scientific and accurate management ability greatly.
