讲座内容:

High Asia, referred to the Tibetan Plateau and its surrounding mountains, contains the largest inventory of glaciers outside of the Polar regions and is regarded as the “Water Tower of Asia”. These glaciers provide headwaters for many Asia’s great river systems. The advance and retreat of these glaciers affect water resources, ecosystems, and the livelihoods of more than 1.5 billion people in South and East Asia. In this presentation, I will introduce my recent work in studying the timing and extent of glacier and lake changes in high Asia at different time scales based on remote sensing, geomorphological mapping, optically stimulated luminescence (OSL), and cosmogenic nuclide (CN) dating techniques. This research not only helps reveal the long-term relationship between climate change and glacier-lake fluctuations in high Asia, but also improves the understanding of the on-going environmental change due to climate change and increased anthropogenic pressure.
