氢氧稳定同位素作为示踪剂被广泛用于水文循环过程研究。地表水是水循环的重要组成部分,是区域水汽来源和现代水文过程分析的有效载体。基于新疆第三次科学考察,于2018年8月至2023年8月在昆仑山北坡采集了地表水样本并测量其氢氧稳定同位素数据,同时汇编了区域以往的地表水同位素数据,分析了昆仑山北坡地表水氢氧稳定同位素的空间分布特征。结果表明:(1) 昆仑山北坡地表水同位素值呈现出西低东高的空间变化特征,区域地表水线为δ2H=5.98×δ18O-6.86(R2=0.65,n=141)。(2) 对比昆仑山北坡地表水和降水氢氧稳定同位素值发现地表水同位素平均值普遍低于加权降水同位素值。(3) 昆仑山北坡地表水同位素空间格局受到西风携带的外来水汽和局地再循环水汽共同影响,此外蒸发也会改变区域地表水同位素值。

Stable hydrogen and oxygen isotopes are widely used as tracers in studying hydrologic processes. Surface water is an important component of the water cycle, and it is an effective vehicle for analyzing regional moisture sources and modern hydrologic processes. We collected surface water samples from August 2018 to August 2023 on the northern slope of the Kunlun Mountains during the Third Xinjiang Scientific Expedition and measured the stable hydrogen and oxygen isotope values. Additionally, we compiled the previous surface water isotope data in the region. We analyzed the spatial distribution characteristics of the stable hydrogen and oxygen isotopes of surface water on the northern slope of the Kunlun Mountains. The results showed that: (1) The surface water isotope values on the northern slope of the Kunlun Mountains showed spatial variations characterized by low values in the west and high values in the east. The local surface water line is δ2H=5.98×δ18O-6.86 (R2=0.65, n=141). (2) A comparison of the stable isotope values of surface water and precipitation on the northern slope of the Kunlun Mountains reveals that the regional surface water isotope value averages are generally lower than the weighted precipitation isotope values. (3) The spatial distribution of surface water isotopes on the northern slope of the Kunlun Mountains is influenced by the interplay of two key factors: the water vapor advection by westerly winds and the local recycled moisture; additionally, evaporation also changed the regional surface water isotope values.
