英文摘要	The unique soils of frozen peatlands have been studied in the northern taiga of West Siberia. These soils form on peculiar peat spots, the vegetation on spots is completely absent for decades. Morphological characteristics, chemical properties of soil of peat spots, as well as their functioning have been studied in comparison with the typical soils of frozen peatlands, developing under the vegetation. Peat profi le of soils of peat spots is thicker and more transformed. Peat of studied soils is more decomposed, and more acidic. The content of total carbon is signifi cantly higher in soils of peat spots (50.3 ± 2.1 % for peat spots and 45.7 ± 4.5 % for typical soils) as well as the total nitrogen content (2.4 ± 0.4 and 0.8 ± 0.5 %, respectively). Essential diff erences in the functioning were revealed. So, average annual ground temperatures and extremes are higher in the soils of peat spots. It was revealed that on sites with bare surface the emission of carbon dioxide is 2 times less on average, than on the sites under vegetation. The content of microbial biomass carbon is lower too (250.1 ± 94.6 and 729.0 ± 71.9 mkg/g, respectively).
