冻土层是受永久冻土层影响的土壤,永久冻土层是冻结两年或两年以上的土壤(ACGR, 1988)。冻土层在活土层(每年冻结和融化的永久冻土层的表层)和永久冻土层的上部都有形成。根据分类的要求,冻土层的控制剖面可以是1米或2米深,并且必须包含永久冻土层(土壤分类工作组,1998;土壤调查人员,1999)。
Cryosols are soils whose development is affected by permafrost, ground that remains frozen for two or more years (ACGR, 1988). Cryosols develop both within the active layer, the surface layer of the ground above permafrost that freezes and thaws each year (Muller, 1947), and in the upper portion of the permafrost. For the requirements of classification, the control section for a Cryosol may be 1 or 2 m deep and must contain permafrost (Soil Classification Working Group, 1998; Soil Survey Staff, 1999).
