“亚洲水塔”本世纪末外流区径流量增幅最高可达49%

Core Insights - The second Qinghai-Tibet scientific expedition has revealed a significant enhancement in the water supply capacity of the Qinghai-Tibet Plateau, with an estimated increase in runoff in the outflow areas of up to 49% by the end of this century [1] Group 1: Water Supply and Climate Change - The warming and humidification of the climate has led to an imbalance in the "Asian Water Tower," characterized by a rapid decrease in solid water bodies such as glaciers and snow, alongside a widespread increase in liquid water bodies like lakes and rivers [1] - Over the past 40 years, there has been a continuous increase in runoff in major river basins such as the source of the Yangtze River and the Lancang River [1] Group 2: Future Water Resource Management - Despite the projected increase in water volume from the "Asian Water Tower," the rapid population growth in most countries in South Asia and Central Asia means that the increased upstream water supply will not meet the growing water demand [1] - There is a need for regional strategies and international coordination to manage water resources effectively, including the establishment of scientific early warning systems for disasters such as ice avalanches and glacial lake outburst floods [1] - The sharing of China's successful water resource management experiences and the implementation of more effective sustainable water management measures are essential for building a water resource community in the "Asian Water Tower" [1]
