| Summary: | The paper deals with structure of permafrost peatlands from the southern part of the Bolshezemelskaya Tundra region. The soil-geocryological complex of peatlands was found for three constituents in its structure as ’active layer – upper permafrost – lower permafrost’. Profile distribution and composition of some soil organic matter components at peatlands was studied. The humus state parameters which are accessed on base of fraction-group humus composition data are good markers of formation conditions of active layers and permafrost rocks in soils of peatlands from the south- eastern part of the Bolshezemelskaya Tundra region. The most indicative among them are: carbon content of water-soluble organic compounds, humic to fulvic acids ratio,ratio of fractions in composition of humic acids. Zero vegetation cover on peat circles corresponds with low content of easy-mineralizable organic compounds in soil which provide plants with nitrogen and nutrients. |
