关于冰期演变三个问题的讨论

施雅风和李吉均（1994）在总结80年代以来中国冰川学研究的新进展中,提出了3个有待深化和争论的问题：1）不同地区最大冰期出现先后差别的原因尚不清楚;对是否存在一种与季风区相反的模式,即冰期与雨期同步;3）在冰期变化中"气候因素与构造因素何者为主".这3个问题也可以说是本世纪冰川学研究留给下世纪的3个问题．它的解决只有冰川学、气候学和地球动力学等的结合才有可能文章拟对此3个问题提点看法,以期"抛砖引玉"．

Discussions of Some Questions on the Glaciation Evolution

Three questions in need of further studies have been proposed by Shi Yafeng in 1994 based on the progress of glaciology studies in China. 1) the reason for the inconsistency of glacial maximum in different regions; 2) possibility of another glaciation evolution pattern, i.e., the glacial Period is simultaneous with the rainy phase, which is quite different from the monsoon region pattern; 3) in glaciation evolution did climatic or tectonic factors play a major role? The above mentioned points are the basic questions in glaciology facing towards the 21st Century and expected to be solved on the basis of the interdisciplinary combinations among glaciology,climatology and geodynamics. Some viewpoints were put forward in present paper as a preliminary attempts.
