| 摘 要： | 以仙人谷国家森林公园不同干扰梯度下形成的3个森林类型(阔叶林、针阔混交林、针叶林)为研究对象,研究分析了这3类森林群落结构特征对不同干扰强度的响应。结果表明,仙人谷国家森林公园森林群落的种类组成、垂直结构特征、乔木层物种的重要值及各层次物种多样性等群落结构特征对不同强度的干扰表现出一定的规律性,随着干扰强度的增大,各群落乔木层物种数逐渐减少,各层物种多样性基本上呈下降趋势,干扰强度中等的针阔混交森林中灌木层种类最多。

| Abstract: | Based on the data collected from three kinds of landscape forest(broad-leaved forest,broad-leaved mixed forest and needle-leaved forest) of Xianrengu national forest park in Sanming,the responses of stand structure of three kinds of forest to different disturbance intensity were studied.The results showed that the responses of species composition,the characteristic of vertical structure,the importance value of arbor layer and species diversity,etc to different intensities of disturbance showed regularity in some extent.With the increasing of disturbance intensities,the number of species of arbor layer decreased and species diversity of various layer basically declined.The species of shrub layer of the needle-broad leaved forest with medium intensity disturbance were the most. |
