Introduction:Snow,ice and environment over the Tibetan Plateau

青藏高原是世界海拔最高的高原,是全球环境变化研究的典型和热点区,也是我国“一带一路”倡议的重要区域,拥有除极区外全球最大淡水储量,高原冰雪、气候、生态环境变化备受关注。2017年8月,国家主席习近平强调青藏高原是亚洲水塔,是生态安全屏障,需特别关注高原地区的生态环境承载力和可持续发展问题。

The Tibetan Plateau,also known as the Qinghai-Tibet Plateau,is the highest plateau in the world.Not only is it a typical area and hot spot for research on global environmental changes,but also an important region in the Belt and Road(B&R)Initiative in China.As it possesses the world’s largest freshwater reserve outside the polar areas,there have been great concerns for changes in glacier,snow,climate and ecological environments in this region.In August 2017,President of the People’s Republic of China Xi Jinping emphasized that the Tibetan Plateau is the water tower of Asia and an ecological security shield;special attention should be paid to the sustainable development of the plateau region and the carrying capability of the region’s ecological environments.
