Abstract—

Pedogenesis on the terraces of lacustrine–alas depressions in the tundra zone of the Kolyma Lowland takes place on sediments that are different in genesis but have significantly similar composition and properties. Soil morphology and soil cover patterns on terraces and slopes of depressions reflect the main trends of the Holocene pedogenesis and the rearrangement of the environment. On the terraces of the upper and middle levels, as well as on the interfluves, the major pedogenic trend is cryozem formation. On the lower terraces and in the bottoms of lacustrine–alas depressions, gleyzation and peat formation are considered to be stable and progressing processes. Soil formation is affected by close permafrost table (<1 m); therefore, all soils are qualified for Cryosols.

科雷马低地苔原带湖滨-阿拉斯s陷的土壤和沉积物

摘要-

在科雷马低地的苔原地带的湖相-阿拉斯洼地阶地成岩作用发生在成因不同但组成和性质明显相似的沉积物上。洼地阶地和斜坡上的土壤形态和土壤覆盖模式反映了全新世成岩作用和环境重新排列的主要趋势。在上层和中层的阶地，以及在插层上，主要的成岩趋势是冷冻酶的形成。在较低的阶地和湖床-阿拉斯洼地的底部，回潮和泥炭的形成被认为是稳定且不断发展的过程。土壤的形成受永久冻土台（<1 m）的影响；因此，所有土壤均符合低温溶胶的标准。
