species similarity

On the other hand, we conducted cluster analysis on reptile community based on species similarity coefficients.

同时以物种相似性系数为基础，对爬行动物群落进行聚类分析。

The continuity of the habitat type and distribution of the species could be seen by calculating the similarity index.

通过对群落相似性指数的计测可以看出生境类型与物种分布具有连续性。

Meanwhile, the result showed some similarity and difference on flavonoid composition among caespitose bamboos, scattered bamboos and other species in the Gramineae.

同时也表明丛生竹在黄酮成分上与散生竹及其它禾本科种类的区别与某些一致性。

On the contrary , the niche similarity among the species with small niche breadths was lower.

而生态位宽度较小的物种, 生态位相似性比例较小.

The structure of grasshopper community in different environment in Luo River region was compared using species-abundance model, diversity index, similarity analysis, principal component analysis and stepwise regression.

应用种-多度分布模型、多样性指数、相似性分析、主成分（PCA）分析及多元逐步回归等方法比较了洛河流域不同生境的蝗虫群落结构。

Species turnover ( Cody index ) paralleled patterns of community similarity ( C J )

Cody指数也有类似的趋势,原因在于物种丰富度的变化.
