| 摘 要： | 本文从群落及其组成结构等方面分析了闽北长期封禁保护的森林（ｃｏｎｓｅｒｖｅｄｆｏｒｅｓｔ，ＣＦ）和人为干扰后的退化森林（ｄｅｇｒａｄｅｄｆｏｒｅｓｔ，ＤＦ）群落物种多样性，结果认为，ＤＦ群落的植物物种丰富度和ＳｈａｎｎｏｎＷｉｅｎｅｒ指数与ＣＦ群落相近或略高，但ＤＦ群落植物种类组成和层次结构的物种多样性发生明显变化，群落物种种群基础已改变，稀有种和渐危种缺乏，这正是ＤＦ与ＣＦ群落物种多样性的本质差异。

| Abstract: | This paper analyzes the species diversity of the long closed conserved forest(CF) and the degraded forest(DF) caused by human disturbance in northern Fujian Province. The result indicates that the plant species richness and Shannon Wiener indices in DF communities are similar to that in CF communities. But the species diversity of composition and layer structure had significantly changed. The basis of species population in community had consequently degraded. There is less rare and extincting species in DF communities than that in CF communities, and the species diversity in CF community is practically different than that in DF community. |
