Abstract
The results of long-term evaluation of carbon stock and current carbon sequestration based on the example of pine-dwarf shrub-sphagnum biogeocoenoses on Vasyugan mire are given. In different climatic conditions (different years) NРP varies from 206 to 337 g C m-2 x year-1. An increase in intensity of carbon emissions was revealed in drier vegetation periods. Most of the carbon losses are determined by emission of carbon dioxide (the average is 61.3 g C m-2 x year-1, or 23.5 % of NPP). Progression of peat formation may be stated. The removal of the carbon by mire waters calculated by the mathematical model is 3.0 % of NРР with an average value of the removal of 7.9 g C m-2 x years-1. On the basis of the model of vertical growth of mires was calculated present-day rate of carbon accumulation from 10.3 g C m-2 x years-1 in polygonal mires to 51.7 g C m-2 x years-1 in grassy mires.
