Аннотация: The aim of this work is to assess the contribution of the components of plant community—biomassand mortmass of tree stands, undergrowth, living ground cover, and forest litter—to its total organic matterpool. The study object is represented by a coniferous-deciduous forest located in the Solnechnogorsk city district of Moscow oblast and characterized by five permanent 50 × 50-m test plots laid in it. The greatest contribution to the total organic matter mass of the studied plant communities is made by perennial parts andmortmass of the forest stand (to 87% and 14%, respectively). The proportion of phytomass of deciduous treesin stand comprises from 32 to 98%, which is connected with the incomplete forest restoration succession. Thecontribution of forest litter does not exceed 3%. Low litter reserves (0.18–1.21 kg m–2) and the destructivetype of all litters are not typical for spruce forests. The floristic composition and the ecological–coenoticstructure of the living ground cover are typical for the subzone of coniferous-deciduous forests; and its contribution to the total productivity of forest biogeocenosis is insignificant. The spatial pattern of litter reservesand of the biomass of the living ground cover within the biogeocenoses is disturbed in comparison with typicalspruce forests due to the high proportion of deciduous species in the forest stand. Their participation in thetree layer is typical for the final stage of formation of a secondary coniferous forest during succession andcauses a slight increase in the intensity of the biological cycle, which is indicated in our case by a decrease inthe reserves and a simpler structure of litters. Since the biomass and mortmass of tree stand contribute mostto carbon sequestration by forest biogeocenoses, these components require a detailed assessment duringmonitoring surveys, the purpose of which is to evaluate carbon reserves of land ecosystems.
