Abstract


Modeling of dynamics of the biosphere for the period of 1860-2100 on spatial model of a global cycle of carbon in the biosphere on the basis of new world these industrial emissions of carbon dioxide of the countries of the world till 2010 is carried out. Calculations for the countries of the largest emitors of CO2 in the atmosphere and the BRICS group countries are made. In 2010 absorption by ecosystems in the territory of Russia almost equaled to emissions of CO2 while the largest emitors of CO2 China, USA, Japan and India were strong emitors of CO2 and a little it absorbed. It is shown that thanks to increase of concentration of carbon dioxide in the atmosphere, despite considerable cutting down of rainforests and an erosion of soils in Brazil, India, the Republic of South Africa growth of concentration of CO2 and temperature in these countries led to increase in year production and phytoweight and a humus countrywide that compensates effect of partial reduction of phytoweight from cutting down of trees. During the modelled period the greatest gain of phytoweight occurred in Russia, the lowest - in the Republic of South Africa.
