摘 要：
应用调查所获的物种丰富度指数(S)、Simpson指数、Shannon-Wiener指数和Pielou指数研究分析了甘肃连城国家级自然保护区8种主要森林类型的植物物种多样性特征。研究结果表明:8种主要森林类型乔、灌、草3层植物物种多样性最高的类型是红桦林、青杄林和祁连圆柏林;在其不同的森林层次上,物种丰富度指数S、Simpson指数和Shannon-Wiener指数表现出乔木层<灌木层<草本层的特点;8种主要森林类型乔木层的Shannon-Wiener指数随其垂直分布海拔高度的变化不明显,而灌木层和草本层的Shannon-Wiener指数总体呈现出随垂直分布海拔高度的上升先升后降的规律,即其最高值出现在此几种主要森林类型垂直分布的中段。

摘 要：
The plant species diversities of 8 major forest types in Gansu Liancheng National Nature Reserve were studied by calculating and analyzing the species richness index,Simpson index,Shannon-Wiener index and Pielou index.The study results showed that Betula albo-sinensis forest,Picea wilsonii forest and Sabina przewalskii forest had the highest diversity in tree layer,shrub layer and grass layer respectively.The species diversity index,Simpson index and Shannon-Wiener index showed the characteristics of tree layer
