Abstract:

Based on the Markov theory, we simulate the density changing process of Larix olgensis industrial plantation, and the rational density and relative tending measure were proposed. It is shown that Markov theory can indeed reflect the diameter transfer process of Larix olgensis industrial plantation. It would be beneficial to analyze the diameter distribution dynamic principle of Larix olgensis industrial plantation quantitatively, so as to determine the suitable density controlling measure. For the density controlling intermediate cutting of Larix olgensis industrial plantation, we should cut the small diameter trees as the dominant not only considering from the point of cultivation forest but also from obtaining wood and increasing forest benefit, It is best to manage a 20-25-year-old Larix olgensis industrial plantation with 0.7 management density.

Key words: Larix olgensis, Industrial plantation, Density controlling technique, Markov theory
