INPUT PART OF THE CARBON BALANCE IN DIFFERENT METHODS OF TREE FELLING IN THE URAL FORESTS FROM THE POINT OF VIEW OF ECOSYSTEM FORESTRY

 Continuously accruing anthropogenous load of a surrounding medium caused change of a resource and raw paradigm in use of the forest by the person on biospheric stabilizing that is entered in the common concept of steady management of the woods and ecosystem forestry. Raw functions of the woods which priority value was indisputable throughout the entire period of existence of a human civilization, at the end of the last century naturally paled into insignificance with a biospheric role of forest resources. Management activities in the forest now requires a detailed environmental study, as an increasing deforestation causes an imbalance of carbon in the biosphere and related adverse climate change. Therefore, advanced technology logging must take into account their impact on carbon-deposited and oxygen-producing functions of forests. To estimate the carbon balance of forest ecosystems extensive information about the dynamics of a biomass require. In this paper the biological productivity of the table used pine and birch forests of the Ural region. On the basis of the known patterns of changes in the current increment of growing stock, depending on the completeness the formula proposed, which includes the dependence of the current gain of a biomass after logging on stand growth and growing source of stem wood ratio of stocks of both. In order to obtain the greatest growth of biomass of forests and minimize the loss of carbon sequestration when logging suggested conducting selective cutting, allowing a greater extent to solve environmental problems, providing inexhaustible ecological and resource potential of forest resources in sustainable forest management.
