安徽岭南森林群落物种多样性的研究

Study on plant species diversity in the forest communities in Lingnan in Anhui Province

在安徽岭南自然保护区内4种群落类型中进行样地调查的基础上,采用物种丰富度指数、多样性指数、均匀度指数对保护区森林群落物种多样性进行了研究,发现自然恢复的群落中植物种类多,分布均匀,优势种不明显;人工更新的林分中植物多样性低,优势种明显;群落结构上,4种类型多样性的大小顺序是灌木>乔木>草本。

This paper studied the species diversity of forest communities in Lingnan Natural Reserve by the investigated species richness index,species diversity index and species evenness index in 4 types of the communities. The results showed that the communities restored by nature had plenty of plant species, even distribution and non-obviously dominant species; the stand restored by human had less species diversities and obviously dominant species. Species diversity indexes of different layers in the forest stands were as follows ： shrub layer 〉 tree layer 〉 herb layer.
