目标规划在同龄林收获调整中的应用

An Application of Goal Programming on Even-aged Forest Harvesting Regulation

本文运用目标规划方法研究了同龄林的收获调整。以浙江省开化县林场作为应用例,建立了4个多目标数学规划模型,选择的目标为木材收获、贴现收益、期末总蓄积。文中提出了一种确定最佳调整期的方法。通过求解,每一模型得到了4种经营策略。最后经决择分析,推荐了一个多目标的经营策略。

Harvesting regulations in even-aged forests ane studied by using goal programming which is applied to the data from Kaihua Forest Farm in Zhejiang provence. Four multi-objective mathematical program models are established. Three goals which are selected in the models are maximization of timber yield, discounted revenue and growing stock. A method to determine optimum regulatory period is suggested before goal programming is used to solve the models. Finally, a multi-objective management policy is put forward.
