摘要/Abstract

摘要： 降水氢氧同位素受气温、降水量、海拔、水汽来源等多种因素控制，是研究区域水文循环过程的重要手段。基于祁连山中段排露沟流域3个站点降水稳定氢氧同位素数据（δ¹⁸O、δD、d-excess）和气象观测资料，结合临近GNIP站点监测资料和HYSPLIT 4.9模型对流域降水同位素特征及水汽来源进行分析。结果表明：流域降水δ¹⁸O值波动范围大（-32.32‰~+3.23‰），季节性变化明显，冬季δ¹⁸O值较低，夏季δ¹⁸O值较高。降水δ¹⁸O和δD值与日均气温均存在密切正相关关系，即温度效应明显。受山区气候和地理条件影响，各站点局地大气降水线（LMWL）截距和斜率相似；与临近GNIP站点（张掖）进行对比，流域降水明显受局地水汽和二次蒸发影响较少。降水d-excess值表现出与δ¹⁸O值相反的季节性变化趋势。结合HYSPLIT 4.9气团轨迹模型，得出流域夏季水汽主要来源西风环流输送，冬季受西风环流和极地气团共同影响。

Abstract: Hydrogen and oxygen isotopic composition of precipitation affected by a variety of factors, such as temperature, precipitation amount, altitude, vapor source and others, is the important tool for investigating the regional hydrologic cycle. The variations of δD and δ¹⁸O values in every rain and snow samples at three stations along the Pailugou catchment from November 2012 to December 2013 were presented in this syudy. The hydrogen and oxygen isotopes in individual precipitation events exhibited extensive variation. The δ¹⁸O varied from +32.32‰ to +3.23‰, while the δD values ranged from -254.46‰ to +12.11‰. Results showed that the δ¹⁸O displayed a distinct seasonal variation, with enriched values occurred in summer and relatively depleted in winter. There was a statistically significant positive correlation between the δ¹⁸O and δD values and local surface air temperature at all the three stations, which was valuable for regional quantitative temperature reconstruction. The Local Meteoric Water Llines (LMWLs) for three stations had similar intercepts and slopes, which reflected the regional climate feature. The nearest Global Network of Isotopes in Precipitation (GNIP) station (Zhangye), compared to the LMWLs for the Pailugou catchment, showed the obvious recycled moisture and secondary evaporation effects with lower intercept and slope. Additionally, the d-excess parameter in precipitation exhibited an anti-phase seasonal variability with the δ¹⁸O. The 96-hr back trajectories for each precipitation event using the HYSPLIT model indicated a dominant effect of westerly air masses in summer and the integrated influence of westerly and polar air masses in winter.
