摘　　要：基于87块黄杉林林分生长数据,采用林分生长竞争指数与Richard生长方程相结合的方法建立林分胸径生长量方程,然后以林分密度与林分胸径作为状态变量,以林分综合价值作为指标函数,建立黄杉林最优经营规划的离散确定性动态规划模型。为解决多目标决策问题,通过设定材积与碳汇的权重,有效解决森林经营中木材生产与增加碳汇储量之间的对立关系。结果表明:通过动态规划方法对林分密度加以控制,可以明显的促进林分综合价值的增长。Based on the data from 87 pieces of Douglas fir forest,the competition index and Richard growth equation were applied to establish the growth equation in terms of DBH. Then,both of stand density and DBH were taken as state variables,and the comprehensive value of the stand was set for index function. Consequently,a discrete deterministic dynamic programming model concerning optimal operation of Douglas fir was built up. By setting the given weight of volume and carbon sink,the confliction between the production of timber and the improvement of carbon sink in forest management was supposed to be settled down efficiently. The results showed that the comprehensive value of the stand can be improved by adjusting the stand density.
