草本层 meaning in English
field layer
field stratum
ground layer
herb layer
herbaceous layer
Examples
- The vertical structure of each forest community were obvious and could be divided into tree layer , shrub layer , herbage layer and lianas
各群落垂直结构十分明显，可分为乔木层、灌木层、草本层和层间植物。 - The species diversity index of the tree layer was a bit low , and the general trend was shrub layer > treelayer > herb layer
乔木层物种多样性指数偏低,垂直结构各层次间物种多样性大小依次为灌木层>乔木层>草本层。 - The complicated vertical structure could be divided into tree layer , shrub layer and herb layer , as well as a definite number of interstratum plants
群落垂直结构复杂,可分为乔木层、灌木层和草本层,并有一定数量的层间植物。 - The species richness and diversity index of the tree layer and the shrub layer was obviously higher than that of the herb layer , and their evenness had evident difference
乔木层、灌木层的物种丰富度、物种多样性指数均大于草本层,且差异极显著,群落均匀度差异显著。 - The results were following : ( l ) generally , all four indices showed the similar variation patterns in species diversity ; ( 2 ) generally speaking , the order of species diversity indices changed with the pattern : shrub layer tree layer herb layers ; ( 3 ) the species diversity of evergreen broadleaved forests was larger than that of warm conifer forests ; ( 4 ) the species diversity of forests in meizi lake area has been affected by human factors
结果表明： ( 1 )梅子湖森林植被样地物种多样性测度的结果，上述4种指标总体上表现出相同的变化趋势。门）总体看来， 14个样地的物种多样性指数在群落不同层次的变化规律为：灌木层乔木层草本层。 （ 3 ）不同植被类型的物种多样性特征是：常绿阔叶林暖性针叶林。
