摘要

The problem of global climatic warming is often related to an increase in the concentration of greenhouse gases in the atmosphere [1]. Among these gases methane is mentioned, whose contribution to warming is assessed as 15% of the total effect of allgreenhouse gases. Its concentration in the atmosphere increased two times over the last two centuries, and is now 1.7 ppm. The proportion of biogenic methane in its global emission makes up 50 to 70%; its main sources are hydromorphic soils, bogs, and irrigated paddy soils. The share of technogenic sources of methane produced by the gas industry is assessed as 10-25%. According to the global inventories of atmospheric methane, its lithospheric fluxes either make up 20-25%, or are completely neglected [1, 2]. At the same time, there is a sorption of atmospheric methane (runoff) in the soil, hence, a decrease in its concentration in the greenhouse gases.
