三峡生态与环境空间信息查询分析系统是一个面向多主题的、空间数据和非空间监测数据有机结合的WebGIS系统.对系统的数据源以及系统主要功能的设计和实现进行了详细阐述.该系统实现了基础地理空间数据8级缩放、空间数据和非空间监测数据联合属性查询等多种功能,实现了面向主题的饼状统计专题图、柱状统计专题图、颜色渲染专题图等多种专题图分析表达,清晰、直观.它不仅为监测站点、科研机构、政府管理部门提供了有利的帮助,也为其他WebGIS系统的开发应用提供了参考.

Three Gorges eco-environmental spatial information search and analysis system is based on WebGIS that is multi-subject oriented and organically combining spatial data with non-spatial monitoring data. Spatial data storage is in the support of Oracle and ArcSDE software. ESRI company's ArcIMS software is adopted as WebGIS development platform. The data source, the design and implementation of the system's main function were illustrated in detail. The main functions of the system were as follows: (1) Basic geographic spatial data's zoom in, zoom out in 8 levels. (2) Basic station property's search and analysis combing spatial data with non-spatial monitoring data. (3) Pie statistics theme map, column statistics theme map and color rendering theme map, etc. These representations of data were clear and straightforward. The system could support for monitoring stations, scientific research institutions and government, and provide the reference to other WebGIS-based system's design and development.
