青海乌兰盆地地下水资源评价及可开采潜力分析

Groundwater resources evaluation and exploitable potential analysis in Wulan Basin,Qinghai Province

针对青海乌兰盆地面临的以水定产的问题,为进一步了解乌兰盆地水文地质条件和地下水资源情况,评价其地下水资源量及可开采潜力,基于乌兰盆地地下水赋存规律,结合勘查结果和拟建水源地开采布局等情况,建立了研究区地下水资源数学模型。结果表明,乌兰盆地地下水可开采资源量为8.5万m^(3)/d,地下水资源开采系数小于0.4,开采程度低,综合分析认为乌兰盆地地下水资源可开采潜力巨大。

In view of the problem of determining production by water inWulan Basin,Qinghai Province,in order to further understand the hydrogeological conditions and groundwater resources in Wulan Basin and evaluate its groundwater resources and exploitable potential,a mathematical model of groundwater resources in the study area was established based on the occurrence law of groundwater in Wulan Basin,combined with the exploration results and the exploitation layout of the proposed water sources.The results show that the exploitable groundwater resources in Wulan Basin are 85000 m^(3)/d,the exploitation coefficient of groundwater resources is less than 0.4,and the exploitation degree is low.Comprehensive analysis shows that the exploitable potential of groundwater resources in Wulan Basin is huge.
