Аннотация: The unique soils of frozen peatlands have been studied in the northern taiga of Western Siberia. These soils form on peculiar peat spots, from which the vege-tation is completely absent for decades. Morphological characteristics, chemical proper-ties of the soil of peat spots, as well as their functioning have been studied in compari-son with the typical soils of frozen peatlands developing under the vegetation. The peat profile of the soils of peat spots is thicker and more transformed. The peat of studied soils is more decomposed and more acidic. The content of total carbon is significantly higher in the 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 1.5 ± 0.5 %, respectively). Es-sential differences in the functioning were revealed. So, the 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 on average 2 times less than on the sites under vegetation. The content of microbial biomass carbon is lower, too (250.1 ± 94.6 and 729.0 ± 71.9 g/g, respectively).
