中文摘要	本文通过环境同位素水化学等分析方法研究了祁连山北侧、龙首山、巴丹吉林沙漠、古日乃、拐子湖和额济纳盆地的泉水和井水的来源，揭示了巴丹吉林沙漠等下游地区的下水来自于祁连山降水的补给，平均补给高程为3 300 m，祁连山顶部存在大片裸露的灰岩地层，雪水融化后沿着喀斯特地层或山前大断裂补给到深部，穿过龙首山直接补给到巴丹吉林沙漠及其下游地区，在沙漠湖泊中发现的钙华与钙质胶结证明地下水经过了石灰岩地层，承压水通过越流补给到浅部含水层，通过蒸发量计算得到的地下水补给量接近6 * 10~8 m~3/a，承压水中地下水的年龄为20～30 a。
英文摘要	In this paper, the sources of spring water and well water on the northern side of the Qiiian Mountain and in lx?ngshou Mountain, Badain Jaran Desert, Gurinai, Guaizi Lake and Ejina Basin are studied by the methods of environmental isotopes and water chemistry. The groundwater in downstream areas such as Badain Jaran Desert is found to be recharged by the precipitation of the Qi-lian Mountain, with the average recharge elevation being 3 300 m. Lots of naked limestone layers exist at the top of the Qiiian Moun-tain. The melted snow water of the Qiiian Mountain infiltrates into the deep layer, passes through the karst strata or large faults in front of the mountain, and directly recharges Badain Jaran Desert and its downstream areas via the Longshou Mountain. The calcare-ous cement and travertine found in the lakes of the desert prove that the groundwater passes through the limestone layer. Confined water recharges the shallow aquifer by means of leakage. The calculation of the evaporation amount shows that the groundwater recharge volume is six hundred million cubic meters per year, and the age of the confined groundwater is 20～30 years.
