Permafrost and Glacier Change and Its Impacts on the Ecosystem and Environment in Tibetan Plateau and the Countermeasures
Abstract:The unique natural environment and ecological systems in Tibetan Plateau are extremely sensitive to climate change. With the development of globle warming, glacier retreat and permafrost degradation have had direct effects on the regional ecological and environmental security and sustainable development directly, and have affected the ecological security barrier function of the Tibetan Plateau in a negative way. Based on the continuous observations, field investigations and experimental researches, the suggestions of establishing the monitoring and early warning system for glacial lakes, landslides, debris flows and permafrost degradations, and carrying out the researches of disaster prevention measures and demonstrations were provided.
Keywords:Tibetan Plateau  glacier retreat  permafrost degradation  regional impact  countermeasure
