摘　　要：鱼卡河下游位于柴达木盆地北部边缘的马海盆地,地下水是当地重要水源之一。通过搜集气象、水文资料及查阅相关文献,结合野外实地考查与试验,在掌握其水文地质基本特征的基础上,计算了其地下水系统2000~2013年的地下水均衡量。结果表明:对于流域内的地下水系统而言,河流渗漏补给是其主要补给源,约占总补给量的77.8%,而潜水蒸发是其主要排泄方式,约占整个系统排泄量的85.6%。流域内地下水年均补给总量为10 260.5万m^3/a,年均排泄总量为108 96.6万m^3/a,地下水均衡差为636.1万m^3/a,地下水位呈59 mm/a的下降趋势。研究结果对流域地下水资源量计算、地下水环境以及生态环境保护等均具有一定的参考价值。The lower Yuka River is in Mahai Basin near the north border of Qaidam Basin,and groundwater is one of the key water sources there. We calculated water budget of the groundwater system from 2000 to 2013 based on basic the characteristics of hydrogeology,and coupled with the meteorological and hydrological data obtained from relevant literature and field investigation and test. The results show that river leakage recharge is the main source of groundwater system in the valley,accounting for77. 8% of the total replenishment; and phreatic water evaporation is the main discharge form,accounting for 85. 6% of the total discharge. The total annual average replenishment to groundwater in the valley was about 10 260. 5 × 104m3/a,and the total annual average discharge of groundwater was about 10 896. 6 × 104m3/a. The groundwater balance difference was- 636. 1 × 104m3/a,and the groundwater level declined at a speed of 59 mm/a. The results are significant for groundwater resources calculation,groundwater environment protection and ecological environment protection for the basin.
