摘  要：
利用矩阵模型模拟了带岭林业局东方红林场森林资源30a间在无干扰以及采伐量为5%、10%和15%,采伐周期为10a的动态变化规律。结果表明:30a内在无干扰情况下森林总蓄积年增长率为2.14%;采伐量为5%、10%、15%时,蓄积年平均增长率分别为1.96%、1.78%、1.59%,且林分结构没有较大的变化,说明东方红林场的现有资源已不适合于大强度采伐。若考虑综合效益,应采用采伐量为5%,采伐周期为10a的经营策略。

摘  要：
An investigation was conducted to study the dynamic change of forest resources in Dongfanghong Forest Farm of Dailing Forestry Bureau during 30 years under the conditions of no-interference and felling volume of 5 percent,10 percent and 15 percent.Forest resources with a cutting interval of 10 years were simulated based on matrix model.Results show that the annual increase rate of forest volume is 2.14 percent under no-disturbance,while the annual average increase rates under the felling volume of 5 percent,10 percent and 15 percent are 1.96 percent,1.78 percent and 1.59 percent,respectively.There is little change in stand structures,which indicates that the existing forest resources in Dongfanghong Forest Farm are not suitable for high cutting intensity.The management mode with a reasonable felling volume of 5 percent and a cutting interval of 10 years should be adopted,considering the comprehensive benefits.
