[Simulation of the competition for light in forest stands of the same age]

A model simulating the growth and interaction of trees during their competition for light has been proposed and verified. Qualitative analys of the model behavior at various values of parameters determining the tree growth rate has been performed. The model verification shows a sufficiently high accuracy of the model approximation of empirical tree growth data. To study interspecific interactions in forest communities, some computing experiments on the development of mixed forest stands, represented by the main forest-forming wood species of the Far East, have been carried out.
