Abstract: | The biogeochemical cycle of organic carbon in Russian terrestrial ecosystems in 1990 is considered. Its components have been estimated as follows: net primary production, 4354 million metric tons of carbon (Mt C); annual amount of plant detritus, 3223 Mt C; heterotrophic soil respiration, 3214 Mt C; biomass utilization, 680 Mt C; damage to vegetation caused by fire and pests, 140 Mt C; and removal by surface and ground waters, 79 Mt C. Anthropogenically regulated fluxes of organic carbon (820 Mt C) are comparable to its amount involved in the natural cycle. |
