本文研究了埃文基亚中部森林低温土壤中微生物营养类群的数量组成和酶活性。在较短的生长期内，北方土壤上层有机层的生物活性与西伯利亚南部针叶林土壤的生物活性相当。中西伯利亚南部针叶林土壤的微生物区系和生物活性已得到相当全面的了解。与此同时，在北方西伯利亚地区的森林土壤的生物特性的信息是稀缺的，虽然有代表性的数据造林，土壤，生理和生物化学研究的森林古生植物。
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.
