山东南水北调水质系统污染源三维GIS开发研究

The Three-Dimensional GIS Development Research of Pollution Sources of Water Quality System in Shandong South-to-North Water Diversion

利用现代信息技术实现南水北调薛城小沙河控制单元水质污染源三维地理信息系统。通过GIS与MIS有机集成实现了水质污染源普查信息的展示及在三维场景中的定位、查询、统计与空间分析功能,为南水北调沿线水环境污染综合治理提供了可视化的决策支持平台,对南水北调东线治污具有重要的现实意义。

The mode information system （3 rn information technology is used to implement the three-dimensional geographical D GIS） of the control pollution source unit of the Xiaoshahe River of Xuecheng Ctiy in the south-to-north water diversion project. Through the integration of GIS and MIS, the system realizes the display of the water pollution source census information and the location, query, statistics and spatial analysis in the 3D scene, providing a visual decision-making platform for the comprehensive control of water pollution along the south-to-north water diversion line. So, it is significant to cope with the pollution of the east line of the south-to- north water diversion.
