Abstract
The biospheric role of forests of Russia is usually judged about by the forest area, area covered by forest vegetation and by forest resources. Lately, these indicators have begun to be supplemented by estimations of the pools of phytomass carbon (Cphyt) and organic carbon of soils (Csoil). The contribution of the forest cover to the biospheric processes may be correctly estimated only resorting to the functional indicators of vegetation. Considered as the main ones of such indicators are usually the net primary production (NPP) and its above-ground part (AbNPP). The scarce number of experimental estimates of NPP for forest ecosystems of Russia makes it necessary to look for calculation methods of estimating AbNPP and NPP. The relations between the AbNPP and the phytomass of fore.
