中国霍普齐沙漠腹地发现了自流井和湖泊。土壤剖面分析显示，当地包气带蒸发强烈，始终处于缺水状态，降水无法渗入地下水。本研究表明，土壤水和地表水是由地下水补给的，而地下水是通过外部水源补给的。对降水中稳定同位素和水收支的分析表明，青藏高原羌塘盆地的地表水可能相当于霍普齐沙漠的地下水。
Artesian wells and lakes are found in the hinterland of the Hopq Desert, China. Analysis of soil profiles has revealed that the local vadose zone is always in a state of water deficit because of strong evaporation, and precipitation cannot infiltrate into the groundwater. This research indicated that soil water and surface water are recharged by groundwater and that the groundwater is recharged via an external source. Analyses of the stable isotopes in precipitation and of the water budget suggested that surface water in the Qiangtang Basin on the Tibetan Plateau might correspond to the groundwater in the Hopq Desert.
