摘要
利用中国林科院热带林业实验研究中心2009年森林资源二类调查数据,分别利用目标线性规划与传统森林轮伐公式计算热林中心马尾松纯林和杉木纯林用材林年采伐量,比较分析同一个经理期(2009—2019年)两种计算方法的不同;结果表明:轮伐公式计算的采伐量一般偏大,且目标规划单位面积年经济收益是轮伐公式获得经济效益的10 20倍。利用目标规划法在同时实现材积收获量最大、出材量最大、净现值收益最大的目标前提下,对森林结构进行调整,使资源分布满足可持续经营的要求,即尽可能达到法正状态。
Based the forest resource inventory data of Experimental Center of Tropical Forestry, Chinese Academy of Forestry, the annual cut of Masson pine （Pinus massoniana） and Chinese-fir （Cunninghamia lanceolata ） timber forests were calculated by multi-goal programming and traditional rotation cutting formulas separately, and the differ- ent results for the same management period （2009 -2019） from these two approaches were discussed. It shows that the harvest is generally larger by rotation cutting formulas, and the annual economic benefits of unit area by goal programming is 10 - 20 times that by rotation cutting formulas. Application of goal programming in forest harvest can regulate forest structure for normal forest, make forest better and achieve the maximum timber harvest and produc- tion and maximum net present value.
