Multi-target Layout and Decision-making of the Management of Forest Ecosystem for Dailing Forestry Bureau

以实现林业资源可持续发展为目的 ,建立了森林生态系统经营多目标优化模型 ,并利用该模型对黑龙江省带岭林业局 12个林场及 1个苗圃的森林资源经营进行了多目标决策。以生态效益、社会效益和经济效益作为指导性目标 ,公益林效益、多功能林效益和商品林效益作为可操作性目标 ,使森林生态系统整体效益达到最优的情况下进行多目标规划决策 ,以此调整森林资源结构 ,恢复地域性顶极群落。如果作为实现规划目标基础的森林经营演替模型、保育经营措施在带岭林业局将来能被严格地执行 ,地带性顶极群落组成的森林生态系统将会得到有效恢复 ,森林生态系统整体效益也将得到有效的优化。

Multi-target optimization model for forest ecological system management was established aiming at the realization of sustainable development, and multi-target decision-making was carried through in terms of the management of forest resources of 12 forest farms and 1 nursery at Dailing Forestry Bureau in Heilongjiang Province.
