永久冻土
永冻土（英语：Permafrost，又译永冻层、永冻土层或多年冻土）是一个地质学的名词，指当冻土层（frost soil）处于水的结冰点以下超过两年的状况。
永冻层一般分布在地下30~40厘米处，通常又分为上下两层，上层夏季融化，下层仍处于冰冻状态。
永久冻土地带的泥土不一定有水份，例如在无孔基岩（不透水的岩石）里就不可能有水；但在大多数情况下，水不单存在，而且更超过地表物料的潜在水饱和量。
一般的冻土层在气候回暖或受到强压时，冻土内的冰会溶解成为水；但永久冻土的所在之处，即使在天气回暖之时，气温仍然在结冰点以下，使冻土内的冰不能再次溶化成为水份，因而使冻土的组成不变。其持续冰冻时间可长达1000年以上。

Permafrost 永久冻土

In geology, permafrost is ground, including rock or (cryotic) soil, at or below the freezing point of water 0 °C (32 °F) for two or more years. Most permafrost is located in high latitudes (in and around the Arctic and Antarctic regions), but alpine permafrost may exist at high altitudes in much lower latitudes. Ground ice is not always present, as may be in the case of nonporous bedrock, but it frequently occurs and it may be in amounts exceeding the potential hydraulic saturation of the ground material. Permafrost accounts for 0.022% of total water on earth and exists in 24% of exposed land in the Northern Hemisphere. It also occurs subsea on the continental shelves of the continents surrounding the Arctic Ocean, portions of which were exposed during the last glacial period.
