摘要
本文对建立同龄林收获调整的多目标数学规划模型进行了探讨,并以一个实例为调整对象,运用模型编制了森林收获调整计划。最优化决策标准是森林龄级结构调整、收获量均衡、最大总收获量和最高贴现纯收益。最优化步骤是:(1)组织经营单元并制定其可能的收获策略;(2)获得多目标最优解并依此编制收获调整计划。应用结果表明,本文的多目标规划授型能够较好地应用于同龄林的收获调整。
A multi-objective mathematical programming model was developedand used in making out a optimal harvest and regulation plan for the even-aged plantation of a forest district.The decision criteria were regulation offorest age-class distribution,even-flow harvest,maximum timber yield,and marimum discounted netincome in the model.The procedure to make outa plan was:first,to organize the“management unit”and formulate any fea-sible cutting schedule for each unit;secondly,to select an optimal solutionset of the model and by means of it to compile a forest harvest and regulati-on plan.
