摘要:

冰川是冰冻圈最重要的组成部分之一,冰川物质平衡是对气候变化最直接的响应。青藏高原被称为“亚洲水塔”,探明该地区山地冰川物质平衡变化,对评估海平面和水资源变化以及预警冰雪灾害风险具有重要意义。受“高原放大效应”影响,青藏高原升温速率高于全球平均水平且持续增暖,高原气候向暖湿化发展。西风和季风是青藏高原气候与环境变化的决定性因素,青藏高原冰川近年来基本处于退缩状态并在20世纪末加速损失,其中季风影响区的冰川退缩强烈,西风影响区的冰川趋于稳定甚至部分冰川出现前进现象,西风-季风过渡地区的冰川退缩程度减弱;青藏高原东南部冰川加速亏损,西北部冰川萎缩速率较小,冰川总面积在未来持续减小。高原大部分冰川对气温变化的敏感性高于对降水的敏感性,极端天气和大尺度环流对冰川物质平衡变化也有重要影响,但其影响机制亟需进一步加强研究。开展青藏高原地区冰川物质平衡变化研究,仍面临很多挑战,是冰冻圈科学领域未来的前沿科学问题和重点工作。

Abstract:

The glacier is one of the most important components of the cryosphere, and the glacier mass balance is the most direct response to climate change. The Qinghai-Tibet Plateau (QTP) is known as the “Water Tower of Asia”. It is important to explore changes in the mountain glacier mass balance in the plateau to assess changes in sea level and water resources and provide early warning of the risk of ice-snow disaster. As a result of the “plateau amplification effect”, the QTP is warming at a rate higher than the global average. It continues to warm, and the plateau climate is becoming warmer and more humid. The westerlies and monsoon are the determining factors of climate and environmental change on the QTP; the glaciers in the monsoon-influenced area retreat strongly, the glaciers in the westerlies influenced area tend to stable or even advance in part of the glaciers, and the degree of glacier retreat in the westerlies-monsoon transition area is weakened. The loss of glacier mass is accelerated in the south-east of the QTP, while the shrinkage rate of the north-west glaciers is smaller, and the total glacier area will continue to decrease in the future. Most of the glaciers on the QTP are more sensitive to temperature changes than to precipitation, and extreme weather and large-scale circulation also have an important influence on changes in glacier mass balance, but research on the mechanism of their influence needs to be further strengthened. Researching changes in glacier mass balance in the QTP still faces many challenges and is a future frontier scientific issue and priority for cryosphere science.

Key words: Glacier mass balance, Response to climate change, Climate sensitivity, Qinghai-Tibet Plateau (QTP)
