Korovin G.N., Korzukhin M.D. Determination of matrices of natural regeneration from forest inventory data // Forest Science (Lesovedenie). 2013. No 5. С.13-19. The paper deals with the natural regeneration after clear cuts. The share of each specie in species composition and area at a regeneration site after cut or forest death is considered. The issue is reduced to determination of elements of the regeneration matrix. For N number of species the matrix consists of N2 elements. The N balance equations having N2 unknown values are derived. These equations could only be solved by introducing additional assumptions, exemplified in the paper. The universal analytical algorithm of finding the solution for any N is proposed. The necessary initial data includes areas occupied by mature stands before cuts, and by juvenile stands regenerated (for all species). The approach proposed can be used in solving the regeneration issues in case of disturbances like forest fires. Natural regeneration, species composition, modeling.. |
