将林分生长——收获模拟程序结合到动态规划(DP)算法中,同时决定最优的疏伐时间和疏伐强度以及伐期龄,可以改善同龄林经营管理中营林投资的决策分析。已经提出了可处理各径阶内树木株数的林分生长模型,但是以各径阶内保留株数作为决策变量的DP算法,其计算工作量和存储量是相当大的。因此,仅通过限制用来确定疏伐决 Combining the stand growth-harvesting simulation program with the dynamic programming (DP) algorithm and determining the optimal thinning time, thinning intensity and cutting age can improve the decision-making analysis of silvicultural investment in the same age forest management. The stand growth model that can handle the number of trees in each diameter order has been proposed. However, the DP algorithm which takes the number of leaves in each diameter order as a decision variable has considerable computational workload and storage capacity. Therefore, only the limits used to determine the thinning out
