本文在已探讨的林分生长规律的基础上，应用动态规划原理对山西管涔林业局云杉天然林的最优采伐方案进行了探讨。提出了此片森林的前期、中期、后期最适采伐强度范围，模拟了进行合理采伐的经济效果，确定了最优主伐年龄，为林业生产实践提供了理论指导。 Based on the discussed stand growth rules, this paper discussed the optimal harvesting plan of natural spruce forest in Guanzhong Forestry Bureau of Shanxi Province based on the dynamic programming principle. The optimal range of harvesting intensity of the forest in the early, middle and late stages was proposed, the economic effects of reasonable harvesting were simulated, and the optimal cutting age was determined, which provided the theoretical guidance for the forestry production practice.
