万家寨引黄工程太原供水区地下水资源保护

在分析万家寨引黄工程太原供水区地下水开发利用现状的基础上,指出地下水超采引起的环境水文地质问题有:泉水断流;区域地下水水位下降并形成大面积降落漏斗,含水层疏干或产水量减少;由于地下水水位下降,导致地下水水质污染加重及地面沉降。提出应对供水区地下水资源加强保护,防止污染;压缩超采,划定禁采区和限采区;建立监测与管理信息系统,利用经济杠杆,全面节流,优化调配,逐步实现引黄水和本地水资源的联合运用。

Protection of groundwater resources in Taiyuan water supply area of Wanjiazhai Yellow River Diversion Project

On the basis of analyzing the current situation of groundwater development and utilization in Taiyuan water supply area of Wanjiazhai YRDP(Yellow River Diversio Project), a series of environmental hydrogeologic problems caused by over-exploitation of the groundwater are revealed. It is proposed to strengthen the protection of groundwater resources, to prevent pollution, to reduce over-exploitation, to plot out areas with or without exploitation permission, and to establish a monitoring and management system. Through rational regulation of groundwater resources of water supply area, connection between Yellow River Diversion water and local water resources is established.
