贵州丹寨老冬寨自然保护区桂南木莲群落研究

Study on Manglietia chingii Community Characteristics of Laodongzhai Nature Reserve in Danzhai County of Guizhou Province

文章调查、分析贵州丹寨老冬寨自然保护区的桂南木莲天然群落的植物种类、群落外貌和垂直结构,计算乔木层的物种多样性。结果表明:老冬寨保护区天然桂南木莲群落植物共有21科31属34种;群落垂直结构明显,分为乔木层、灌木层、草本层和层间植物;群落的物种多样性指数较高,物种较丰富;桂南木莲在群落中处于优势地位;群落结构已基本稳定。

The plant species,physiognomy and vertical structure of Manglietia chingii natural community in Laodongzhai Nature Reserve,Danzhai,Guizhou were investigated and analyzed,and the species diversity of tree layer was calculated.The results showed that there were 34 species belonging to 31 genera and 21 families in the natural Manglietia chingii community in Laodongzhai Nature Reserve;The vertical structure of the community was obvious,which was divided into tree layer,shrub layer,herb layer and interlayer plants.The species diversity index of the community was high and the species were abundant;Manglietia chingii was in a dominant position in the community;The community structure had been basically stable.
