摘要
以材积收获量最大为目标,建立了线性规划模型,以确定最优直径分布、最优立木度、最优择伐周期以及最优采伐决策等异龄林经营所必须解决的问题。用动态优化模型解决了在最短的时间内把现实林调整到最优异龄林分结构的问题。根据洮河林区的现实情况,用实际调查的材料,通过模型,对该林区冷杉异龄林提出了最优收获调整目标和最优收获调整决策。
The linear programming model which could maxmize the timber volume was developed for determining the optimal values of diameter distribution, growing stock, cutting cycle and harvest decision of uneven-aged stands management. In the meantime, the problem regulated an actual uneven-aged stand structure to the optimal structure in minimal time was solved with the dynamic optimization model. The optimal yield regulation target and decision of Abies uneven-aged stands in Taohe forest were put forward in accordance with the real conditions of the forest and the data of on-the-sport investigation.
