METHANE EMISSION FROM NATURAL COMPLEXES OF THE ZAKAMYE LOWLANDS IN THE TERRITORY OF UDMURTIA

The methane content largely determines the oxidizing properties of the atmosphere, including greenhouse gases and polluting components. The purpose of this study is to estimate the amount of methane emissions from natural sources. The volumes of methane emission from a typical section of the swamp massif within the Zakamye lowlands in the Udmurt Republic were obtained experimentally. Analyzing the results obtained in the course of this work, it can be concluded that the most intensive methane supply is observed in the tracts located in the floodplain of the Kama River and its tributaries. These tracts are characterized by a high level of soil moisture, and as a consequence, active anaerobic processes in the soil during the warm season. Slope and watershed landscapes are characterized by minimum methane emissions, which is associated with a greater degree of aeration of soils of these territorial units.
