英文摘要	Hydrogen and oxygen isotopes in precipitation have been widely used as effective traces to investigate hydrological processes such as evaporation and atmospheric moisture source. This study analyzed delta D and delta O-18 of precipitation in continuous event-based samples at three stations of Pailugou Catchment from November 2012 to December 2013. The delta O-18 and delta D values ranged from -32.32aEuro degrees to +3.23aEuro degrees and from -254.46aEuro degrees to +12.11aEuro degrees, respectively. Results show that the delta O-18 displayed a distinct seasonal variation, with enriched values occurring in summer and relatively depleted values in winter, respectively. There was a statistically significant positive correlation between the delta O-18 and delta D values and local surface air temperature at all the three stations. The nearest Global Network of Isotopes in Precipitation (GNIP) station (Zhangye), compared to the Meteoric Water Lines for this study, showed the obvious local evaporation effects with lower intercept and slope. Additionally, d-excess (delta D - 8 delta O-18) parameter in precipitation exhibited an anti-phase seasonal variability with the delta O-18. The 96-h back trajectories for each precipitation event using Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model indicated a dominant effect of westerly air masses in summer and the integrated influence of westerly and polar air masses in winter.
