本部分定量地分析了五指山森林植被的垂直分布规律并对该森林植被进行了数值分类．在森林植被的数值分类过程中，本文尝试性地提出了新的改进方法，在数值分类时，充分地考虑了群落的组成戍分和结构特征，先把各群系中的物种，按重要值大小排列，然后按公式进行群落相似系数计算，最后用组平均法进行聚类分析，取得较为理想的效果．
This section quantitatively analyzed the vertical distribution of forest vegetation in Wuzhishan and numerically classified the forest vegetation. In the process of numerical classification of forest vegetation, this paper tentatively put forward a new improved method. In the process of numerical classification, the composition and structure of the community are fully considered. First, the species in each group, according to the importance value Size arrangement, and then according to the formula of community similarity coefficient calculation, and finally using the group average method of cluster analysis, and achieved more satisfactory results.
