Moreover, Pielou evenness index was higher than that in the two native plant communities.

而Simpson优势度指数和Pielou均匀度指数较土著植物群落中高。

Shannon-Wiener index and Pielou evenness index were used to compare and check the feasibility of rarefaction in practice.

多样性指数之间的比较，需要样方的面积大小相等，否则没有实际意义。

The results showed that Pielou evenness index, gap-fraction, openness, stand basal area, and stand density were influenced by spatial structure of the community at a broad scale.

结果表明，群落均匀度指数、空隙度和开度、林分胸高断面积和林分密度在大尺度上表现出显著的空间结构。

The other indexes (Shannon-Wiener index, Simpson index and Pielou index) of tree, shrub and plant were not significantly different among all kinds of islands.

乔木、灌木、木本的Shannon-Wiener多样性、优势度和均匀度指数在不同面积的岛屿类型上没有显著差异。
