南极无冰区古气候与冰盖进退历史研究进展

The Research Progress on the History of Palaeoclimate and Ice Sheet Advance and Recession in the Antarctic Ice-free Areas

环南极洲无冰区就是随着气候变暖、冰川后退而出现 ,是研究南极乃至全球的自然环境演化历史的理想场所。本文主要介绍了国内外学者在恢复无冰区古气候、古环境演变与冰盖进退历史方面所采用的主要手段和方法 ,并着重论述了近几年关于南极半岛、西南极和东南极环海岸一带无冰区的冰川作用历史与古气候研究成果 ,指出了目前研究中所存在的问题 。

The ice-free areas in circum Antarctica appear with the climate becoming warm and the ice sheet retreating ,which are the ideal sites to study on the environmental evolutional history in Antarctica ,even on the global environmental change. In this paper, we mainly discussed the dominating measures and methods by which the scholars reconstruct the palaeoclimatic, palaeoenvironmental change and the history of ice sheet advance and recession in the Antarctic ice-free areas, and we emphasize on dissertating the research progress the history of the glaciation action and palaeoclimate in the ice-free areas around the coast in Antarctic peninsula, West Antarctica and East Antarctica. Finally, the main problems during present research have been pointed out, and the issues to be resolved in the future have been shown.
