A synthesis of the impact of Russian forests on the global carbon budget for 1961–1998

摘要: An attempt is made to synthesize the current understanding of impact Russian forests on global carbon (C) budget for period 1961–1998 (37 years), based a detailed inventory pools and fluxes in 1988–1992, historical reconstruction full forest 1961–1998. All major intermediate indicators (phytomass, net primary production, disturbances, soil respiration, etc.) were independently estimated compared with earlier reported results. During entire period, C land (FL, 882.0 × 10 6 ha 1998) increased by 433 Tg yr −1 , which 153 are accumulated live biomass, 57 above- below-ground dead wood, 223 sequestered soil. A significant part this increase deals land-cover changes. The annual average uptake FL from atmosphere, defined flux-based method, be −322 lateral transport lithosphere hydrosphere comprised 47 (including charcoal), considered “missing sink.” uncertainties (excluding unrecognized biases) averages range ±5–8% ±24% out/into atmosphere ecosystem exchange, respectively (a priori confidential probability 0.9). If change excluded, sink 1961–1998, both pool- methods, was 268 ± 94 272 68 respectively. results line recent estimates Northern Eurasia inverse modeling at continental scale, if classes other than contribute total terrestrial vegetation.
