多年冻土在青藏高原有着广泛的分布,因其远离极地基本冻土带,具有它自己的一系列特点,而为中外学术界所关注。本文试从区域对比的角度,概略探讨青藏高原多年冻土分布状况、影响因素、厚度变化、温度动态、冻土构造、融区分布以及形成时代和发展趋势方面的一些特点,从而说明其与极地和高纬度地区的多年冻土有着明显的差别。 Permafrost is widely distributed in the Qinghai-Tibet Plateau, because of its far from the polar basic tundra, with its own series of characteristics, but for the Chinese and foreign academic attention. This paper tries to discuss some characteristics of permafrost distribution, influencing factors, thickness changes, temperature dynamics, permafrost structure, melting zone distribution, forming times and development trends of Qinghai-Tibet Plateau from the perspective of regional contrast, There is a clear difference between permafrost and high permafrost regions.
