甜槠林群落结构及物种多样性特征研究

Study on community structure and species diversity of Castanopsis eyrei

在分析不同海拔高度甜槠林群落结构及物种重要值特征的基础上,应用物种多样性的丰富度指数、多样性指数、均匀度等指标测定甜槠群落不同海拔梯度物种多样性,分析甜槠林物种多样性梯度变化效应。结果表明,甜槠群落物种多样性梯度变化规律明显;总体上物种多样性高,种类组成复杂,群落乔木层、灌木层、草本层层次明显。

Based on the analysis of community structure and species important value characters of Castanopsis eyrei in different altitude, the species diversity of the community and the species diversity altitude gradient variation effects were studied by using species abundance index, diversity index and uniform index. The results indicated that the species diversity variation in Castanopsis eyrei community was obvious and the species structure was complicated. The species had high diversity in species composition, clear layers of arbors, shrubs and herbages.
