青海省茫崖市供水水源地下水天然资源量评价

Evaluation of groundwater natural resources in Mangya City,Qinghai Province

青海省茫崖市作为省内最年轻的地级市,自建市以来一直没有集中供水水源。为解决茫崖市生产及生活用水需求,在主要富水区域—阿达滩河和斯巴利克河冲洪积扇开展供水水文地质研究工作,通过断面径流量法和补给量总和法法对拟建水源地的地下水天然资源量进行评价,最终确定研究区地下水天然资源量为21.47×10^(4)m^(3)/d,为后续水源地的建设提供水量依据。

Mangya city,as the youngest prefecture-level city in qinghai Province,has no centralized water supply source since its establishment.In order to meet the demand for production and domestic water in Mangya City,the hydrogeological research work on water supply was carried out in the main water-rich areas-the Adatan River and the alluvial-proluvial fan of the Spark River.The natural resources of groundwater in the proposed water source area are evaluated by the cross-sectional runoff method and the sum of recharge method,and the natural resources of groundwater in the study area are finally determined to be 21.47×10^(4)m^(3)/d,which provides a water quantity basis for the subsequent construction of water source areas.
