| 摘 要： | 选取了4种受不同强度采伐后的次生阔叶红松林乔木群落作为研究对象,利用重要值、多样性指数等指标定量的分析其群落的外貌以及结构的变化,定量研究不同采伐强度对阔叶红松林乔木群落的影响.研究结果表明:采伐改变了群落中物种的优势地位,红松(Pinus koraiensis)的萝要值排名随采伐强度的增加而降低,白桦(Betula ptayphrlla)的重要值排名随采伐强度的增加而上升;采伐改变了阔叶红松林中主要树种的年龄结构.采伐30 a后,红松幼树(胸径<10 cm)占种群数鼍的比例随采伐强度的增加而增加,白桦幼树在种群中的比例随采伐强度增加而减少.由于主要树种年龄结构的改变,群落的演替也受到一定的影响;采伐可以促进阔叶红松林中主要树种的更新.

| Abstract: | In order to quantitative study the influence of different cut intensities on arbor community of broad-leaved Korean pine forest,four secondary arbor communities of broad-leaved Korean pine forest,which were cut by different cutting intensities,were selected as study objects,and the changes of appearance and structure of community were quantitative analyzed by importance value,diversity index and other indexes.The results indicated that harvest cutting had changed the advantage positions of species in commun... |
