摘要
采用树种丰富度、树种组成指数、树种单调度、树木均匀度等指标对林口林业局红石林场的次生柞林的树种组成做了详细的分析,其结果表明:现有次生柞林树种的多样性较差,单调度高,且无针叶树种;柞树生长较慢,生长潜力不大;建议对林分进行适当的人工抚育,并辅以针叶树种(红松、云杉)林下更新,构建异龄复层针阔混交林,发挥森林的多种生态功能。
Tree species composition with species richness, tree species The result showed that the species diversity of existing secondary Quercus mongolica forest is poor, single scheduling is high and no conifer; the stand had slowly growth and little potential; so we suggest to appropriate artificial forest tending,updated with Pinus koraiensis and Picea asperata, and builded different ages stratified needle broad-leaved mixed forest and give play to the multiple ecological functions of the forest.
