Assessment methodology of an optimal plan for forest felling

Abstract

This article discusses the method of estimating the optimal plan for felling. The paper deals with the following objectives: to study the nature of influence of the productivity of pine tree stands on the felling age (according to the ripeness of economic forests), the calculation of the average increase in the value of wood in accordance with the current forest fees as well as the defi ning the age at which most cost-effective cutting of stands is achieved. When optimizing the size of the main use it is necessary to distin-guish two problems which, because of their relationship and influence on each other, must be addressed comprehensively: the establishment of the optimum cutting age, based on the theory of ripeness of the forest, and the determination of the annual allowable cut, taking into account the age structure of forests. Methods of assessing the losses from the delays in the felling may be used in the calculation of the objective functions based on this value, and to compare different options for the design of the main forest use. The indicators of growth of the pine stands: Bagi nsky normal stands, Baginsky modal stands, Zagreyev, Miroshnikov, Yurkevich and the tables of growth of economic forests have been taken as the test data.
