摘要

金沙江下游流域地处干热河谷气候影响区,大气降水对该区域水文循环至关重要。分析了金沙江下游流域降水稳定同位素组成的季节变化特征及其影响因素,结合同位素示踪和HYSPLIT模型探讨了流域大气降水水汽来源。结果表明:金沙江下游流域降水δ²H和δ¹⁸O雨季偏负而旱季偏正,气温和降水量对同位素组成影响较大而高程效应不显著;流域大气降水线斜率和截距均低于全球和我国大气降水线,主要受到非平衡蒸发作用影响;流域大气降水水汽来源和昆明地区类似,雨季降水主要受到西南与南亚季风影响,旱季降水潜在来源为西风带或极地大陆气团。研究成果对金沙江下游区域水文循环具有重要指导意义。

Abstract

The lower Jinsha River Basin is situated in a region impacted by dry and hot valley climate. Atmospheric precipitation plays a pivotal role in the hydrological dynamics of the basin. We scrutinized the seasonal fluctuation patterns of stable isotopic composition in precipitation within the basin, and identified its influencing factors. Furthermore, employing isotope tracing techniques alongside the HYSPLIT (Hybrid-Single Particle Lagrangian Integrated Trajectory) model, we elucidated the sources of atmospheric precipitation in the area. Findings reveal distinctive seasonal trends in isotopic values, with negative values of δ²H and δ¹⁸O observed during rainy season and positive values in dry season. Temperature and rainfall emerge as primary influencers on the isotopic composition of local precipitation, while elevation exerts minimal impact. Notably, the local meteoric water line exhibits lower slope and intercept values compared to global and Chinese atmospheric precipitation lines, primarily due to non-equilibrium evaporation effects. Moisture sourcing analysis indicates a similarity between the precipitation origins in lower Jinsha River Basin and those in Kunming. Rainfall during the rainy season predominantly stems from the southwest and south Asian monsoons, while dry season precipitation potentially results from the westerly belt or polar continental air masses. These research outcomes are of substantial significance for understanding regional hydrological cycle within the lower Jinsha River Basin.
