In the southeastern part of the desert, it is characterized by coexistence of high megadunes and a great number of lakes. Deuterium and oxygen 18 isotope compositions as well as hydrochemistry of groundwater, lake water, soil water and river water were investigated in detail to gain an insight into their relationships and the origin of the groundwater. The results show that the groundwater and the lake water are genetically related, but unrelated to local precipitation and the leakage of Heihe River at northern slope of Qilian mountain. DeltaD and delta{18}O values of deep soil water (lower than 40 cm) and groundwater plot on the same evaporation line Ell, which shows that they have the same recharge source. The point of intersection between Ell and LMWL suggests that the groundwater originates from the water resource which has a weighted mean value that is lighter by some 6 % delta{18}O than the local precipitation in Badain Jaran Desert. {3}H data of water samples shows that the groundwater in Badain Jaran Desert originates from the water recharged after the nuclear test. The deep fault zone underground maybe the water circulation channel based on Helium analysis of groundwater. The result has guiding significance to rational exploitation and utilization of the local groundwater. Доп.точки доступа: Chen, J. S.; Sun, X. X.; Gu, W. Z.; Tan, H. B.; Rao, W. B.; Dong, H.
