- 2对 9个指数的主成分分析 (PCA)表明 ,3个多样性指数中 ,Shannon- Wiener指数受丰富度影响最大 ,其次是 Mc Intosh指数 ,而Simpson指数与丰富度关系较远principal component analysis of 9 indices showed that,among the 3 diversity indices,Shannon-Wiener index had the closest relation to species richness,McIntosh index secondly,Simpson index related remotely to species richness.

- 在植被恢复演替过程中草本层与灌木层物种丰富度指数 (Gleason指数与 Margalef指数 )、多样性指数 (Shannon- Wiener指数 )以及 Pielou均匀度指数的变化均表现为抛物线函数变化规律 :y =at2 +bt+c。Therefore it may suggest that China silkvine and amur maple be candidate plant species for artificial vegetation construction. The change of plant species richness index (Gleason index and Margalef index), diversity index (Shannon-Wiener index), and Pielou evenness index in herbaceous layer and shrub layer csn be described by a parabolic function: y=at~2+bt+c, but the change of diversity in different layers were asynchronous.
