摘要：
The quantitative composition of various trophic groups of microorganisms and the enzyme activity of forest cryogenic soils in Central Evenkia was studied. The preferential development of complexes of psychrotolerant bacteria and micromycetes was found. During a short growing period, the biological activity of upper organic horizons in northern soils is comparable with that in southern taiga soils of Siberia. The microflora and biological activity of southern taiga soils in Central Siberia is understood rather completely. At the same time, information on the biogenic properties of forest soils in northern Siberian regions is scarce, though there are representative data on sylvicultural, soil, physiological, and biochemical studies of forest biogeocenoses.
