摘要/Abstract

摘要： 在群落数量特征、群落层次频度、群落物种多种性等 3个层次上对分布在宜昌大老岭国家森林公园保护区的光叶珙桐 (Davidia involucrata var vilmoriniana)、领春木 (Euptelea pleiosperma)、紫茎 (Stewartia sinensis)、白辛 (Pterostyrax psilophyila)等珍稀群落进行了定性和定量的研究,弄清了群落组成、结构,揭示了群落演替过程、演替阶段,分析了以上几种珍稀树木在群落演替过程中的地位及濒危原因,为三峡库区珍稀树木保护提供了理论依据.

Abstract: The quantitative characteristics,plant frequency in layers and species diversity of David involucrata var. vilnoriniara,Euptlea pleiosperma,Stewartia sinensis and Pterostyrax psilophtila communities at Dalaoling National Forest Park Reserve of Yichang were studied qualitatively and quantitatively.The community composition and structure were made clear,the succession courses and stages of the communities were revealed,and the role of these rare trees on the succession course of communities and the cause of being in imminent danger were analyzed,which provided a theoretical basis for protecting the rare trees in the Three-Gorge reservoir area.
