摘要:

以马尔柯夫过程理论为基础对长白落叶松工业人工林进行了模拟密度控制,提出了合理的培育密度和相应的抚育间伐对象。结果表明:马尔柯夫过程理论确能反映长白落叶松工业人工林的直径转移过程,这对于定量分析长白落叶松工业人工林直径分布的动态规律,从而拟定合理的密度控制措施非常有益;长白落叶松工业人工林成林后的密度控制间伐无论从培育森林方面,还是从取得木材、加大林分收益方面考虑,都应该以间伐小径阶的林木为主; 20-25龄长白落叶松工业人工林的经营密度以0.7为最佳。

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.
