１９８７～１９９５年对降水、黑河水和古日乃草原地下水作了定位观测，在巴丹吉林沙漠水文探险中采集了沙漠和戈壁地下水及湖水。降水同位素组成δＤ～δ１８Ｏ与Ｃｒａｉｇ线相同，但发现了地下水的δＤ～δ１８Ｄ关系平行于降水线且有氘盈余为负且达－２２‰的异常，其成因不明。由地表、地下水环境同位素组成，分析了黑河治理规划实施后可能对地下水资源产生的工程影响，它近期不会成为古日乃草原沙漠化进程的因素，但对额济纳绿洲的影响却不容忽视。
From 1987 to 1995, the precipitation, the Heihe River water and the ancient Japanese grassland groundwater were surveyed. Desert and Gobi groundwater and lake water were collected in the Badain Jaran Deserts Hydrological Exploration. The isotopic compositions of δD ~ δ18O are the same as that of the Craig line. However, the origin of the δD ~ δ18D of groundwater parallel to the precipitation line and the deuterium surplus is negative and reaches -22% o is found. Based on the surface and groundwater environment isotopes, it analyzes the possible impact on the groundwater resources after the implementation of the Heihe River Regulation Plan. It will not become a factor in the process of desertification in the ancient day. However, the impact on the Ejina Oasis can not be ignored.
