Abstract

Currently, the taxonomy of peat soils is not given more attention, especially with regard to taxonomic units in the species rank. The diagnostics of 51 soil profiles in the various oligotrophic mire types in the Numto Nature Park (north taiga subzone of West Siberia) has brought about proposals to improve the existing soil classification. It is suggested to: 1) limit the peat horizon thickness in the peat-gleyzem type to 30 cm; 2) divide the peat-gleyzem type by the trophic status into oligotropic and eutrophic subtypes; 3) expand the list of taxa determined by the botanical composition of peat by means of the division of soil species into subspecies on the basis of classifications of peat and peat deposits; 4) use current vegetation as one of the main diagnostic (indicative) criteria in determining the soil type in mires; and 5) use the degree of decomposition of the peat layer underlying the peat soil for determining the variety of peat soil. The article draws attention to the difficulties in determining the classification position of soils of frozen large mounds in palsa bogs and proposes alternative solutions to this problem.

西西伯利亚北部北针叶林分带的贫营养沼泽泥炭土壤系统中使用俄罗斯土壤分类和诊断的经验

摘要

当前，泥炭土壤的分类没有得到更多的关注，特别是在物种等级中的分类单位方面。在Numto自然公园（西西伯利亚的北针叶林次区域）的各种贫营养性沼泽类型中，对51种土壤剖面的诊断提出了改善现有土壤分类的建议。建议：1）将泥炭-格列ze型泥炭的水平厚度限制为30 cm；2）按营养状况将泥炭-小菜籽类型分为低营养和富营养亚型；3）根据泥炭和泥炭沉积物的分类，通过将土壤物种划分为亚种来扩展由泥炭的植物组成决定的分类单元清单；4）使用当前植被作为确定泥泞土壤类型的主要诊断（指示）标准之一；5）利用泥炭土下面的泥炭层的分解程度来确定泥炭土的种类。这篇文章引起了人们关注，难以确定帕萨沼泽中冷冻大丘陵土壤的分类位置，并提出了解决该问题的替代方案。
