用样地法和无样地法, 结合树干解析, 调查分析了杭州灵隐30 年生木荷常绿阔叶林的林分特征。结果表明, 该群落的层次发育较完整, 木荷等部分优势树种的年龄结构呈倒金字塔形, 存在着被其他树种替代的可能性, 但由于影响群落演替趋势的诸多因素之综合作用, 使得该群落的种类组成能够保持相对稳定。乔木层株数随胸径分布呈现截尾正态分布。不同径级的木荷具有大致相同的树高, 表现出同龄林的特征, 说明群落的结构还将继续变化。优势树种的高生长峰值年龄出现在8~12 a , 胸径平均生长和材积平均生长高峰尚未出现, 群落处于旺盛生长阶段。图1 表3 参3
Using plots plots and plots without plots, combined with the analysis of the trunk, the characteristics of 30-year-old evergreen broad-leaved forest in Lingyin were surveyed and analyzed. The results showed that the community developed more stratifiedly. The age structure of some dominant tree species such as Schima superba was inverted pyramid, and there was a possibility of being replaced by other tree species. However, due to the combined effect of many factors affecting the community succession trend, The species composition of this community can be kept relatively stable. The number of tree layers showed a truncated normal distribution with DBH distribution. Schima superba with different diameters had the same tree height and showed the characteristics of the same age, indicating that the community structure will continue to change. The peak height growth of dominant tree species occurred in 8-12 years. Average DBH growth and average volume growth did not appear yet, and the community was in vigorous growth stage.
