第二次青藏科考新成果发布

Core Insights - The second comprehensive integration of the Qinghai-Tibet scientific expedition has released ten major application results, focusing on ecological protection, disaster prevention, resource energy investigation, and carbon balance accounting [1][2] Group 1: Key Achievements - The establishment of a comprehensive Earth system observation and early warning platform, which includes monitoring and early warning systems for various disaster scenarios [1] - Successful implementation of six early warnings through the established disaster monitoring systems [1] - Development of a fault distribution map along the Sichuan-Tibet transportation corridor and a meteorological disaster monitoring system, optimizing over 400 kilometers of corridor routes [1] Group 2: New Recognitions - The Qinghai-Tibet Plateau is experiencing warming, increased humidity, greening, and darkening trends, which have persisted for decades and are expected to continue into the mid-21st century [2] - Significant enhancement of the Asian water tower's water supply capacity, with projected runoff increases of up to 49% by the end of the century in major river basins [2] - Identification of a tripling risk of ice collapse and glacial lake outburst floods in the future [2] Group 3: Environmental Transformations - The Qinghai-Tibet Plateau has undergone three significant environmental transformations driven by various climatic and geological factors [2] - The new environmental transformations present opportunities for sustainable development, including enhanced water supply capacity and biodiversity services [2] - However, these transformations also pose risks such as imbalances in the Asian water tower and ecological fragmentation [2]
