北京市怀柔应急备用地下水源管理信息系统开发

Development of Management Information System for the Emergency Well-Field,Huairou District of Beijing

北京是一个以地下水供水为主的大都市,约67%的供水依靠地下水。自1999年以来因连续干旱,地表水源锐减,北京市建成了多处城市应急备用地下水水源地,为保障城市供水安全做出了重要贡献。为提高应急水源地管理水平,建立了基于GIS的、集实时监测、统计报表、模拟评价和管理预警于一体的应急水源地管理信息系统(EGWMIS)。该系统的应用提升了地下水水源地的管理水平,增强了地下水开采的科学性,提高了供水保证程度和供水安全。

Beijing is a highly urbanized area that is dependent on a complex water supply system. Groundwater is the largest part water supply with 67%. For the water crisis in recent years, many groundwater emergency well fields have been established. With water supply of the emergency well field, urban water managers will be challenged to conserve more and make the most of water falls directly on this area. To improve water supply safeguard, the Emergency Groundwater Management Information System （EGWMIS） has been developed, which provides for enhancing water management. A structured system design ensures the placing of data within a dynamic context of data deal with, groundwater dynamic analysis, model prediction, water quality assessment and early warning, and its application illustrate EGWGIS how to implement as a core component of a more comprehensive water supply project to provide information to the decision-maker. The EGWGIS is designed around a client- server architecture that emphasizes the seamless integration, sharing and reuse of data to support modeling activities. The GIS spatial data, real-time monitoring groundwater data, water quality sampling information, and MapObjects applications that support and enhance an integrated water field management are discussed. With quick and easy access to discrete information, numeric simulation and assessment models, and GIS, these systems constitute a valuable water resource management tool for water supply decision making.
