摘要
本文论述了东亚"冰期冷槽"的存在、意义。认为"冰期冷槽"理论是中国第四纪研究中的又一项重大突破,对过去发现或遗留下的许多间题和现象给予了合理解释,推动了全球环境系统研究的发展.
A cold trough existed in east China during the Pleistocene ice age, which is a new theory advanced by Prof.Yang Huairen(1980). The theory explains successifully the greatest horizontal and vertical displacement of the climatic belts in east China during the Quaternary ice age and the particularity of paleo-environmental pattern, The causal mechanism of the 'cold trough'is the rising of high mountains and high plateaus in west China since the Pliocene epoch and the weakening of the summer monsoon in east China during the Quaternary ice age. The author considers that the new theory greatly contributes the international academic circles.
