Methodological background for development of a system of growth and productivity models for stands of the main forest-forming tree species of Ukraine
Journal Title: Лісівництво і агролісомеліорація - Year 2016, Vol 129, Issue
Abstract
The article presents the results of scientific research on the development of a system of growth and productivity models for stands of the main forest-forming tree species of Ukraine on basis of the yield tables proposed by Ukrainian scientists. The fundamental prerequisites for creating the system and ways for its further development and improvement are grounded. The methodological ground is formed by the developments of Ecosystems Services and Management Program of the International Institute for Applied Systems Analysis in modeling growth, productivity and bioproductivity of forests. Von Bertalanffy’s growth function serves as a mathematical basis for the research, by means of which fitting of series of dynamics of stand mean height, diameter, basal area sum, growing stock and total productivity was secured for the studied stands. Perspectives for further application of the results and developments described in the article lie in the sphere of integration of the updated description of dynamics Ukrainian forests to regional and global models of dynamics of forest ecosystems to account for the impact of global climate change and forecast their state middle- and long-term prospect.
