摘要: 为探明新疆南部地区河流绿洲带地表水与地下水δD、δ18O特征,于2016年7、8、11月和2017年7、8月在研究区进行δD、δ18O样品采集。通过对河流绿洲带同一时期不同区域、不同时期同一区域的地表水与地下水δD、δ18O在大气降水线上的分布特征分析发现:无论是同时期不同区域还是不同时期同一区域的地表水与地下水δD、δ18O分布特征相似,分布于研究区冬、夏半年降水数据的交汇区域,并没有体现出取样月份的降水同位素特征,并且δD、δ18O值均处于降水-融雪水-冰川水的δD、δ18O值范围内,体现出其补给源存在多样性、变化性、累积性和滞后性的特点;同时,结合研究区实际情况分析表明,河流绿洲带水体的δD、δ18O特征表现出其受到自然因素和人类活动的双重影响。

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.
