摘要:

冰川变化是气候变化的产物,也是气候变化的指示器。在全球变暖的背景下,近百年来我国冰川消融强烈, 以退缩为主。本文对近百年来我国冰川末端退缩、物质平衡变化和冰川面积变化方面的研究成果进行了综合分析, 从时间和空间两方面探讨了我国冰川变化对气候变化响应的敏感性。结果表明,我国冰川末端变化对气候变化的 响应在时间上要滞后10~20 年,冰川末端退缩、物质平衡变化和面积变化的幅度在青藏高原边缘和周边地区要大 于高原内部,对气候变化响应的敏感性也由内部向边缘增强。最后指出了我国冰川变化研究中存在的主要问题及 今后发展趋势。

Abstract:

Glacier variations results from climatic change, it is also an indicator of climatic change. In the past 100 years, glaciers in China have been generaly retreating and ablating rapidly under the condition of global warming. In this paper the researches about glacial terminal retreat, areas and mass balance variations in China in recent decades have been reviewed and analyzed, the sensitivity of glacial variations to climatic change had been discussed from the view of time and space. Evidences indicated that there is a phase lag of about 10-20 years for glacial terminal variation to climatic change in China and the variations magnitude of the glacial retreat, mass balance and glacial areas are larger at the margins and the vicinities of the Qinghai-Tibetan Plateau than the inner glaciers. The sensitivity of glacial variations to climate change displayed an enhanced trend from the inner glaciers to the marginal and adjacent glaciers of Qinghai-Tibetan Plateau. Finally, the authors analyze the problems and insufficiency of the present studies and the tendency in future.
