青藏高原冰川冻土变化对生态环境的影响及应对措施

Permafrost and Glacier Change and Its Impacts on the Ecosystem and Environment in Tibetan Plateau and the Countermeasures

青藏高原特殊的自然环境与生态系统对全球变化极为敏感。气候变暖背景下,冰川冻土退化直接影响该区域生态与环境安全及可持续发展,影响着该区域作为生态安全屏障功能的发挥。在多年连续观测、考察与实验研究的基础上,提出了建立冰川湖、泥石流滑坡、冻土退化的监测预警系统以及进行灾害防治措施研究示范的对策。

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 suggesti...
