【 摘 要 】

The simplified mathematical model of peat deposits growth is suggested based on assuming the swamp is a thermodynamics system Its validation was performed according to the data of the swamps in Siberia It is shown that the peat deposits growth is nonlinear related to climate change Therefore, for the appropriate methods applying in paleoclimatic reconstructions is expedient to establish the optimal values of functioning particular bio- and ecosystem in natural conditions that determine the most probable existence of life forms of biological species.
