| 1. | Takeyou out past the orchard to the trees . head north 它横穿果园然后到达正北方的灌木层 |
| 2. | There was no significant difference of diversity index between the tree layer and the shrub layer 乔木层与灌木层之间多样性各项指标总体无显著差别。 |
| 3. | 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。 |
| 4. | 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。 |
| 5. | 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。 |
| 6. | The results show that the main foctor that affects the natural regeneration is elevation , and the coverages of litter and brushwood were next 结果表明,影响该区森林天然更新的主要因素是海拔高度,其次是灌木层盖度和枯落物层的盖度。 |
| 7. | The plant species of shrub in the fragmental evergreen broadleaved forests are less rich than those in the continuous evergreen broadleaved forest 片断森林的灌木层种类不如连续森林丰富。有些片断森林只是边缘的草本较多,林内的草本种类较少。 |
| 8. | 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。 |
| 9. | At the same special location of small area ( such as 500 m2 ) , neolitsea aurata var . glauca could reach the canopy and became the dominant species of the community . in the typical neolitsea aurata var 同时,缙云山白毛新木姜子种群在小范围内( 500m ~ 2 )可以上升为优势种群;在典型白毛新木姜子群落,灌木层白毛新木姜子重要值最大,成为灌木层最主要的组成树种。 |
| 10. | Therefore , the optimized pattern of this kind of green spaces is small arbor + small shrub + ground layer , the arbors with mass crowns and stand firm are preferential , with the coverage around 40 % and the coverage of shrub around 30 % - 40 % 灌木层宜选择常绿且对so _ 2有一定抗性的种类,为丰富其美学效果,可点缀配置观赏性强的花灌木,灌木层盖度以50 60为宜。 |
