The Tibetan plateau plays an essential role in the water supply to Asia’s large river systems and, as the largest and highest mountain plateau in the world, it drives the Asian monsoon and influences global atmospheric circulation patterns. The increase in the Tibetan plateau lake volume since the mid-1990s is well documented, however the drivers of lake growth remain largely unexplained. In this study we investigate changes in lake and glacier volumes, together with changes in precipitation and evapotranspiration at basin scale. We calculate the contribution of glacier mass loss to the lake volume increase for the period 1994–2015. We demonstrate that glacier mass loss does have a limited contribution to the lake volume increase (19

冰川质量损失对近期青藏高原湖泊流量增加的贡献有限
青藏高原在向亚洲大型河流供水中起着至关重要的作用,作为世界上最大,最高的高山高原,它驱动亚洲季风并影响全球大气环流模式。自1990年代中期以来,青藏高原湖泊数量的增加有充分的文献记载,但是,湖泊增长的驱动力仍然无法解释。在这项研究中,我们调查了湖泊和冰川体积的变化,以及流域规模的降水和蒸散量的变化。我们计算了1994年至2015年期间冰川质量损失对湖泊流量增加的贡献。我们证明了冰川的质量损失对湖泊体积增加的贡献有限(19
