摘　　要：雅鲁藏布江是西藏流域面积最大的河流,在第二次青藏高原综合科学考察阶段,分析雅鲁藏布江流域降水变化规律,有助于深入了解高寒地区水循环与水资源演变规律,对合理开发利用高原地区水资源具有重要的借鉴意义。本文回顾总结了近30 a雅鲁藏布江流域降水研究取得的最新成果,其内容涉及降水时空分布特征、空中水汽密度垂直变化、水汽输送通道特征以及气候变暖背景下降水变化趋势和未来预估。对这些研究成果的梳理,旨在加深对雅鲁藏布江流域降水变化特征的理解和认识,为促进雅鲁藏布江流域降水变化研究提供参考。同时,指出了目前雅鲁藏布江流域降水变化研究中面临的问题,如因地形复杂导致的站点稀疏、观测困难、资料短缺等,需要在未来的科学考察中重点加以关注。The Yarlung Zangbo River is the largest river in Tibetan Platau.During the second synergistic investigation of science for the Qinghai-Tibet Plateaus,analysis of the precipitation variation over the Yarlung Zangbo River basin is helpful for understanding the hydrological cycle and water resource evolution in the alpine region,which has an important significance for the rational development and utilization of water resources in this region.This study reviews and sumerizes the latest achievements in the research of the precipitation variation over the Yarlung Zangbo River basin,including the temporal and spatial distribution characteristics of precipitation,the vertical variation of water vapor density,the characteristics of water vapor channels,and the trend of precipitation change and future projection under global climate warming.The review of the above researches aims at obtaining deep understanding of the precipitation variation over the Yarlung Zangbo River basin and shtrengthening the study of it in this basin.At the same time,some problems in the current research on the precipitation variation over the Yarlung Zangbo River basin are pointed out,such as the sparsity of stations,observation difficulties and data shortage as caused by the complex terrain,which should be paid more attention in future scientific investigation.
