Carbon Balance in Forest Ecosystems and Biotic Regulation of Carbon Cycle under Global Warming: Landscape-ecological Predictive Modeling

It is outlined the concept of biotic regulation of carbon cycle in biosphere with the help of a study of local mechanisms in the small biological cycle. The prognosis of changes of biological cycle and biotic regulation of the carbon cycle according to the HadCM3 scenario of global warming are presented. Two mutually antithetical phenomena of carbon cycle biotic regulation will be developing on the Russian Plain. The extreme south of the forest zone will be the field of significant additional accumulation of carbon in atmosphere. The main positive biotic regulation of carbon cycle, according to the Les Chatellier’s principle, will be performed by broadleaf-coniferous forests of high plains in the nemoral-forest sub-zone and in the southern belt of sub-taiga zone. Local and regional maps of carbon balance are presented as well.
