摘 要:冀中南地区地表水资源严重匮乏,地下水成为主要供水水源,地下水开采量占全区总供水量的85%以上。地下水超采导致浅层、深层地下水位持续下降,2010年与1980年比较,30年间浅层地下水位下降15.79m,平均下降速率为0.52m/a。目前该区中东部平原深层地下水开发已近极限,剩余地下水可开采储量年限仅为3.4a,其中邯郸、石家庄和保定3个地区深层地下水可利用储量已经用完,目前使用的是不允许开采的储量。该文提出对该区实施地下水管制、重新明确限采区和禁采区范围、制定地下水管理政策、提高用水价格等具体措施。As the surface water resources shortage in Middle-South Hebei is severe,groundwater is the major source of water supply which accounts for more than 85 % of the region's total water supply. Groundwater overexploitation causes the shallow and deep groundwater levels declining continuously. Comparing to 1980, the shallow groundwater depth at 2010 has been declined 15.79 m. The rate of decline is 0. 52 m/a. At present,deep groundwater development in the mid-eastern plain of Middle-South Hebei is almost close to the limit. The remaining mineable reserve is only enough for about three years. The deep ground-water available reserve in Handan, Shijiazhuang and Baoding has been exhausted. The groundwater in use currently is the reserve that is not allowed to be exploited. In order to deal with water shortage crisis, the paper presents specific measures to im plement groundwater regulation: to define the scope of restricted area and prohibited area, make groundwater management policy, raise water price.
