摘要:
2014年,在云南省高黎贡山自然保护区分布的大树杜鹃(Rhododendron protistum var. giganteum)群落设置8块标准样地进行调查,分析群落的物种组成和物种多样性。结果表明,大树杜鹃群落可分为4层,包括乔木上层、乔木下层、灌木层和草本层。其中乔木层共有植物14科,23属,30种;灌木层共有植物16科,22属,25种;草本层共有植物14科,21属,21种。大树杜鹃所在群落多样性较高,从群落不同层次的Shannon-Wiener指数、Simpson多样性指数、Margalef多样性指数来看,其多样性为乔木层>灌木层、草本层,灌木层和草本层之间则互有交叉。乔木层平均高、平均胸径的变化与Margalef多样性指数变化一致,但平均高、平均胸径达到一定数值时,Margalef多样性指数不再上升而呈下降趋势。
Abstract:
Eight sample plots were established for investigation on plant species composition and diversity at Rhododendron protistum var. giganteum communities of Gaoligong Mountain, Yunnan province in 2014. The results indicated that the communities could be divided into four layers, namely upper tree layer, lower tree layer, shrub layer and herb layer. There were 30 species belonging to 14 families and 23 genera at tree layer, 25 species belonging to 16 families and 22 genera at shrub layer, 21 species belonging to 14 families and 21 genera at herb layer. The investigated communities had high diversity, evaluated by Shannon-Wiener index, Simpson index and Margalef index, especially the tree layer, was more diversified than shrub and herb layer. Average height and DBH of tree layer had positive relation with Margalef index until a certain value.
