herb layer

With increasing altitude, α diversity, represented by the Shannon-Wiener index, decreased for both tree and shrub layers, with no clear trend for herb layer.

乔木层和灌木层的α多样性（Shannon Wiener指数）呈下降趋势，草本层则变化不明显；

Whereas, for H', D, PIE and Jsw, it is herb layer> tree layer> shrub layer.

但在H′、D、PIE、J（sw）和J（si）方面，表现为：草本层＞乔木层＞灌木层。

Within the same type , the species diversity inedx was shrub layer > tree layer > herb layer.

在同一类型不同层次中,灌木层>乔木层>草本层.

Correlation analysis showed that: In the herb layer, the middle slope and the check have the greatest similar coefficient, in the shrub layer, the similar coefficient between the upper slope and the down slope was biggest. 3.

通过相关性分析表明：在草本层，坡中部和对照有最大的相似性系数，在灌木层，坡上部和坡下部的相似性系数最大。

The diversity indexes of tree, shrub and herb layer in various plots had a little difference.

乔木层、木层、本层的多样性各项指标在群落各样地间均有一定的差异,相对而言, 灌木层、木层的差异较小,草本层的差异较大.
