摘要
本文较系统地阐述了青藏高原多年冻土的地带性规律、冻土构造以及融区的类型和分布特征,详细论述了不同作用下形成的冻土(冰缘)地貌,并对青藏高原的冰缘期进行了初步划分与对比。
In this paper the authors have systematically described the regional distributionalregularities of the pemafrost in Qinghai-Tibetan plateau, the kinds and distributions offrozen ground and melting area, and the frozen(epiglacial) landscapes formed under the dif-ferent geological processes, At last the epiglacial epochs of Qinghai-Tibetan Plateau havebeen divided and compared preliminarily.
