现有资料说明,我国西部高山高原区多年冻土的分布具有明显的垂直分带性,而其它各种地方性的地理-地质因素,对冻土的分布也有着重大的影响。我国西部高山高原地区多年冻土的分布情况相当复杂:多年冻土的分布下界是弯曲的;在一个很小的范围内,就可以遇到各种类型的冻土,其稳定性、冷生组构、含冰量和物理力学性质都有很大的差异;在不同的冻土区内,可以出现各种类型的融区,也可以出现种类繁多的冻土现象。有时,一沟之隔,冻土下界的高程可以相差几百米,並且,在几十米的范围内,冻土特征就有很大的变化,
The existing data show that the distribution of permafrost in the western alpine plateau of western China has obvious vertical zonation, while other various local geo-geological factors have a significant impact on the distribution of permafrost. The distribution of permafrost in the western plateau is rather complicated: the lower bound of the permafrost is curved; in a very small range, it is possible to encounter various types of permafrost whose stability, Structure, ice content and physical and mechanical properties are very different; in different permafrost, there may be various types of financial district, but also can appear a wide range of frozen soil phenomenon. Sometimes, the distance between the ditch and the bottom of the permafrost can vary by a few hundred meters, and within a few tens of meters, there is a great change in the characteristics of the frozen soil.
