herb layer meaning in English
草本层
Examples
- 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 water - holding capacity of altinglia gracilipes , schima superba , fokienia hodginsii and cunninghamia lanceolata planted under cunninghamia lanceolata ecological public welfare forest was studied from forest canopy , shrub and herb layer , litter layer and soil layer
