Addressing Impacts of Glacier and Permafrost Changes on the Qinghai- Tibet Plateau

چکیده
With a unique eco-environmental system, the QinghaiTibet Plateau plays a fundamental role in safeguarding the local socioeconomic development and has an irreplaceable position in ensuring eco-environmental security in China and in the whole of Asia. Over the past 30 years, obvious climate change, predominantly global warming, has an extremely remarkable impact on the cryosphere of the plateau, the world’s largest area of midand low-altitude glaciers and permafrost. What is the effect of these changes on the regional socioeconomic development? How to deal with them? These questions concern both government officials and scientists, and so the CAS Academic Divisions (CASAD) began a research project in 2006. Climate change has led to an accelerated receding of mountain glaciers, says the research report, which was released in 2009. “As a result, mountain disasters, such as glacier lake outburst floods, mud-rock flows and landslides, have become more frequent and serious. In addition, the water levels of lakes are rising to inundate nearby grasslands.” The warming has also caused the melting of permafrost in various degrees, with serious impacts on major road construction and engineering projects, and with direct or potential threats to local environmental and ecological systems, observes the research panel, which comprised more than 20 Addressing Impacts of Glacier and Permafrost Changes on the QinghaiTibet Plateau

Desertification and its relationship with permafrost degradation in Qinghai-Xizang (Tibet) plateau
Desertification in Qinghai-Xizang (Tibet) Plateau is part of Chinese desertification. In the past decades, due to the climate warming, the climate condition in Qinghai-Xizang (Tibet) Plateau has been relatively dry. This has resulted in permafrost degradation and other environmental problems. In addition, the vegetation and the soil layer were also destroyed by unreasonable economic activities....

Ten Dragon 3 projects deal with hydrologic and cryosphere processes, with a focus on the Himalayas and Qinghai – Tibet Plateau, but not limited to that. At the 1 Dragon 3 Progress Symposium in 2013 a significant potential for a better and deeper integration appeared very clearly and we worked out an overview of the ten projects identifying specific issues and objectives shared by at least two p...
متن کاملVegetation Changes along the Qinghai-Tibet Plateau Engineering Corridor Since 2000 Induced by Climate Change and Human Activities
The Qinghai-Tibet (QT) Plateau Engineering Corridor is located in the hinterland of the QT Plateau, which is highly sensitive to global climate change. Climate change causes permafrost degradation, which subsequently affects vegetation growth. This study focused on the vegetation dynamics and their relationships with climate change and human activities in the region surrounding the QT Plateau E...

متن کاملChanges in frozen ground in the Source Area of the Yellow River on the Qinghai--Tibet Plateau, China, and their eco-environmental impacts
The Source Area of the Yellow River is located in the mosaic transition zones of seasonally frozen ground, and discontinuous and continuous permafrost on the northeastern Qinghai–Tibet Plateau. Vertically, permafrost is attached or detached from frost action. The latter can be further divided into shallow (depth to the permafrost table 8 m), deep (>8 m) and two-layer permafrost. Since the 1980s...
