中文摘要	巴丹吉林沙漠以其独特的沙丘湖泊景观而受到关注。地下水对湖泊的强烈蒸散耗水起到了支撑作用,而湖泊群的存在反过来也会影响该沙漠的区域地下水循环模式。在区域尺度上,银根-额济纳旗中生代盆地对巴丹吉林沙漠的水文地质特征具有控制作用。通过水文地质调查和典型湖泊的综合观测,表明沙漠湖水的年蒸发量可以达到1 200~1 550 mm,盐湖形成时间达到千年尺度,本地降水入渗形成的浅层地下水和来自沙漠周边地区的深层地下水对湖水都有贡献。地下水总体上自东向西流动并受到湖泊群的干扰,形成了局部地下水系统与区域地下水系统的嵌套结构。越靠近沙漠东侧,区域侧向径流对湖泊的补给贡献越大,反之则浅层地下水循环对湖泊的补给贡献更大。
英文摘要	Badain Jaran Desert has attracted a lot of concerns due to typical landscape of sand dunes and lakes. Groundwater supports the water demand for strong evaporation loss from the lakes and the groundwater circulation mode has been affected by the group of lakes. At regional scale, the hydrogeological characteristics of Badain Jaran Desert are controlled by the Mesozoic Yingen-Ejina Basin. It is indicated by hydrogeological survey and synthetic observations around typical lakes that the annual evaporation rate of the lake water can be as large as 1200-1550 mm and the formation of these salt lakes elapsed at least 1000 years. Both shallow groundwater that originated from local precipitation infiltration and deep groundwater that transferred from neighborhood area of the desert contribute to the lake water. Groundwater flows generally towards west from east but is disturbed by the group of lakes so that a nested structure of local and regional flow systems is exhibited. The lakes closer to the east edge of the desert are more strongly dependent on the recharge of regional lateral flow of groundwater; otherwise, the lakes tend to be dominated by shallow groundwater discharge.
