Abstract
To describe the successional processes in forest coenoses and spatial distribution of tree species the approach using models of phase transitions was proposed. We introduced a variable equation and phase transition models that describe processes in forest coenoses. The analysis showed that the model considering processes in the forest as a second order phase transitions was in good agreement with the field data. The model parameters can be calculated from the data of field observations and used for the prognosis calculations of successional processes in forest and the distribution of important tree species in high-altitude forest. The proposed approach to the modeling of dynamic processes in the forest as phase transitions is universal that greatly simplifies the task of constructing models of forest dynamics.
