摘要：The article is devoted to the research of the dependence of timber carting out (logging activity) on natural and climatic conditions. Mathematical models are obtained for these dependencies. The modelling was performed for various timber harvesting periods. The result indicates a significant differentiation of factors, that affect the timber carting out depending on the timber harvesting periods. The object of research is the logging areas of the Krasnoyarsk krai, which is one of the largest regions of Siberia.
