调水区多年冻土划分为３个区，冻土面积为１１×１０４ｋｍ２左右，约占全区面积的７２．４％。受全球气候变化及人类经济活动的影响，区内多年冻土处于退化状态。在全球气候持续变暖的情况下，未来５０ａ内，目前厚度小于１０ｍ的多年冻土和岛状多年冻土将消融殆尽，多年冻土面积将减少约１５％，冻土下界上升１５０～２００ｍ；气候变暖，使得季节性冻土层变薄，某些地段的多年冻土消失或变为深埋藏多年冻土等，则可降低工程造价，有利于施工和运营
Permafrost is divided into 3 zones and the permafrost area is about 11 × 104km2, accounting for 72.4% of the total area. Affected by global climate change and human economic activities, permafrost in the region is in a degraded state. Under the condition of global warming, permafrost and island permafrost, currently less than 10m in thickness, will be depleted within the next 50a, the permafrost area will decrease by about 15%, and the permafrost lower bound will rise by 150-200m ; Climate warming, so that the thinning of the seasonal frozen soil, some areas of permafrost disappear or become buried deep permafrost, etc., can reduce the project cost is conducive to construction and operation
