基于GIS的农村人饮供水管网信息系统设计

A Design for Rural Drinking Water Supplying Network Based on GIS

利用地理信息系统强大的数据查询功能、空间数据分析与处理功能、数据与图形的交互显示功能,以黄河流域某农村人饮供水管网为例,建立基于GIS的供水管网信息管理系统。该系统在一个数据库框架下建立12个图层,分别为供水点、已建泵站、新建泵站、已建蓄水池、新建蓄水池、干渠、已建管线、新建管线、移民项目区、支线、公路、边框。系统可完成供水信息统计、供水点按人口数分类显示、供水支线信息统计、供水支线信息分类管理、专题地图绘制等任务,能提高供水管网管理的质量和效率。

Due to its powerful data query capabilities, spatial data analysis and processing capabilities, data-graphics interactive display feature, Geographic Information System（GIS） was used to set up an information management system for rural drinking water supply pipe network in the Yellow River basin. In this system there are 12 layers created in a data framework, which are water supply points, built pumping stations, new pumping stations, built reservoirs, new reservoirs, main canals, built pipelines, new pipelines, immigration project area, branches, highways and borders. The system can be competent in water supply information statistics and water supply points classification. Additionally, branch line infor- mation statistics, information classification management of the branch line and thematic mapping can also be achieved via Geographic Information System. In that case, both efficiency and quality of the water supply pipe network management will be improved.
