寒区冻泉与冰丘形成机理这一问题一直备受人们关注。在充分梳理既有研究成果的基础上,指出:寒区地下潜水排泄到地表的过程主要受冻土因素、气候因素,以及其自身形成、补给、水循环等因素的影响;冻结泉不仅可以由季节性融化层中的冻结层上水形成,还可以由冻结层上地下水形成;在低温作用影响下,引起了地下水在地表排泄口的冻结,促进了冰丘的形成。
The problem of formation mechanism of freezing frost and ice dome in cold area has drawn much attention. On the basis of fully reviewing the existing research results, it is pointed out that the process of excretion of underground submerged fish to the surface in the cold area is mainly influenced by the factors of permafrost, climate, as well as their formation, recharge and water cycle. The frozen spring can not only be affected by the season Frozen layer in the thawing layer of water formation, but also by the freezing layer of groundwater formation; under the influence of low temperature, causing groundwater in the surface drain vent freezing, promoting the formation of ice hilly.
