Abstract: In order to perform a detailed investigation on the variation characteristics of δD and δ18O in the oases in south Xinjiang,the samples of surface water and groundwater were collected in July,August and November 2016 and July and August 2017,respectively.After analyzing the characteristics of δD and δ18O in surface water,groundwater and precipitation in different drainage basins in south Xinjiang in the same period,it was found that the distribution of δD and δ18O in surface water and groundwater was similar.The isotopes were distributed at the intersection of precipitation data in winter and summer,and there was no a seasonal difference.The values were all in the range of δD and δ18O in precipitation,snowmelt and glacier water.Which revealed the diversity,variation,accumulation and lagging characteristics of the recharge sources.Moreover,the characteristics of δD and δ18O in surface water,groundwater and precipitation in the oases were jointly affected by both natural factors and human activities based on considering the actual situation of the study area.

Key words: isotope, surfer water, groundwater, oasis, south Xinjiang
