本文以三个次生林群落类型为对象,运用相对多度(RA)、相对频度(RF)、相对显著度(RD)及重要值(Ⅳ)等指标,对其垂直结构进行了深入分析,运用填充系数(F)对群落的层次结构研究提供重要依据;在参考多种分层系统的基础上运用动态的分层方法对群落的层次结构进行了较为合理的划分;分析了次生林群落的垂直结构特征对于群落生产力及其动态演替趋势的意义. In this paper, the vertical structure of three secondary forest community types was studied by using the relative abundance (RA), relative frequency (RF), relative saliency (RD) and importance (IV) The filling coefficient (F) provides an important basis for the study of the hierarchical structure of the community. Based on the reference to a variety of stratification systems, the dynamic stratification method is used to make a reasonable division of the community structure. The vertical structure of the secondary forest community The significance of characteristics to community productivity and its dynamic succession trend.
