herbaceous layer

The community can be structurally divided into arborous layer, shrub layer and herbaceous layer.

群落可分为乔木层、灌木层、草本层和层间层。

The influences of arboraceous layer on spatial patterns and morphological characteristics of herbaceous layer in an arid plant community

干旱区群落乔木层对草本层空间格局及形态特征的影响

Multiple linear regression analyses showed that the coverage and height ( or depth) of canopy layer, herbaceous layer and leaf litter layer were the most important factors in determining the family richness, abundance, diversity;

多元回归分析表明，林冠层、草本层及枯落物的高（厚）度和覆盖率是决定科丰富度、个体数量、多样性和均匀度的决定因素。

Diversified nature of shrub layer does not suffer too many influences of arbor layer. And diversified nature of herbaceous layer shows to the clearer negative correlation relation with the arbor layer.

灌木层的多样性并没有受到乔木层的太多影响；而草本层的多样性与乔木层表现为较明显的负相关关系。

Arthropods communities were extremely significant difference among the tree layer, shrub layer, herbaceous layer and leaf litter layer, the individual number, species number, species diversity and evenness index of Arthropods were the maximum in herbaceous layer.

节肢动物群落在林冠层、灌木层、草间层和枯落物层4个垂直层次之间有极显著差异，草间层具有最高的物种数、个体数、多样性指数和均匀度指数。
