Abstract—

Cryoaridic soils were proposed to be identified as an individual genetic soil type by Vladimir Volkovintser in the 1970s. Volkovintser argued that the specific properties of these soils are in good agreement with the soil-forming factors: ultracontinental climate, cryoxerophytic steppe or tundra-steppe vegetation, dry permafrost, and skeletal parent material. In cryoaridic soils, the properties of chestnut and pale soils are combined, but their individual features are due to the specific cryohumus AK horizon and secondary carbonates dominated by pendants. Cryoaridic soils were not included in the soviet soil classification system of 1977; in the Russian soil classification system, the type of cryoaridic soils with the AK–BPL–BCA–Cca horizons is included in the order of pale-metamorphic soils with the pale-metamorphic BPL horizon as diagnostic for all soil types of this order. However, our field research, analysis of publications, and the study of soil in the Central Soil Museum give us grounds to verify diagnostic criteria, to change the profile type formula of cryoaridic soils, and to review their taxonomic position in the classification system. We argue that the BPL diagnostic horizon should be replaced by the diagnostic property (pl), which means that cryoaridic soils should be transferred into another order, presumably, the order of humus carbonate-accumulative soils. Some additional subtypes are proposed. On highly skeletal shallow parent materials, cryohumus soils belonging to the order of organo-accumulative soils are developed.

低温土壤作为俄罗斯土壤分类系统中的遗传类型：地理学、形态学、诊断学

摘要-

Vladimir Volkovintser 在 1970 年代提出将低温土壤确定为一种单独的遗传土壤类型。Volkovintser 认为，这些土壤的特定性质与土壤形成因素非常吻合：超大陆气候、低温旱生草原或苔原草原植被、干燥的永久冻土和骨骼母质。在低温干旱土壤中，板栗和苍白土壤的特性结合在一起，但它们各自的特征是由于特定的低温腐殖质 AK 层位和以悬垂物为主的次生碳酸盐。1977 年的苏联土壤分类系统不包括低温土壤；在俄罗斯土壤分类系统中，具有 AK-BPL-BCA-Cca 层位的低温干旱土壤类型包括在具有浅变质 BPL 层位的浅变质土壤的顺序中，作为该顺序所有土壤类型的诊断。然而，我们的实地研究、出版物分析和中央土壤博物馆的土壤研究为我们验证诊断标准、改变低温土壤剖面类型公式以及审查其在分类系统中的分类地位提供了依据。我们认为 BPL 诊断范围应该被诊断属性 (pl) 取代，这意味着低温土壤应该转移到另一个顺序，大概是腐殖质碳酸盐积累土壤的顺序。提出了一些额外的亚型。在高骨架浅母材上，
