The assessment of the carbon pool in representative forest stands of the northern, middle, and southern taiga subzones of Central Siberia, located in the territory of the Krasnoyarsk Kraihas, has been conducted. The area of these taiga regions accounts for 87.5% of the total territory of Central Siberia, and they make the main contribution to carbon deposition in this area. The total mass of deposited carbon in the representative stands of the northern taiga is 73970 thousand tons, in the stands of the middle taiga this value is 1257101 thousand tons, and for the southern taiga, it is 2766554 thousand tons. The average mass of deposited carbon for the northern taiga subzone is 13.2 tons per hectare, for the middle taiga it is 44.6 tons per hectare, and for the southern taiga, it is 64.5 tons per hectare. Such differences are due to the zonal characteristics of the natural and climatic conditions in these areas and, consequently, the varying productivity of the forest stands formed in these taiga subzones. The fractional composition of the carbon pool depends on many indicators, primarily on the bonitet (site quality), density, and fullness of the forest stand. For all the considered representative forest stands, the main contribution to carbon deposition comes from the trunks and roots of trees. In the northern taiga, the share of trunks accounts for 49.9% to 66.7% of the deposited carbon, while roots account for 18.1% to 34.8%. For the middle taiga, these values range from 53.8% to 70.4% for trunks and from 13.2% to 33.4% for roots. For the southern taiga, the share of deposited carbon in trunks is from 53.4% to 69.6%, and in roots, it is from 17.7% to 31.9%. The obtained data on the carbon pool of forest stands in the taiga zone of Central Siberia are important for understanding carbon exchange processes in forest ecosystems, as well as for developing effective strategies for the conservation and management of forest areas in the context of climate change.

Keywords: Central Siberia, carbon pool in forest stands, fractional composition of the carbon pool.
