查询词典 understorey

Hystrix canopy declined slightly at the midday, suggesting the occurrence of reversible photoinhibition. Owing to the lower maximum net photosynthetic rate in sun leaves and the ability to effectively and consistently utilize the scattered light and/or transmitted light, C. hystrix saplings could survive low light intensity, grow well at the edge of the forest and in the understorey, and eventually become one of the dominant species in upper layer of the community.

刺栲冠层阳生叶的最大光合能力比较低，整个冠层叶能高效而稳定地利用散射和透射光，这些特征使得常绿的刺栲幼树能在林边或林下良好生长，较好地适应不同的光环境并成功渡过幼苗期，最终成为群落中的上层优势种。

However, the functional groups in the lower canopy or understorey layer, which had smaller buttress or lighter seed mass, had weak indication to environmental changes.

应用物种的相对生物量、相对胸高断面积、相对多度、相对频度和重要值等5种方法，分别确定了各功能群的关键种。

Forests are important habitats for birds and, in temperate forests, small mammals which inhabit the dense understorey.

森林对鸟类来说是重要的栖息地，而且在温带森林里，小型的哺乳动物居住在稠密的森林下层。

At 8 km distance the eco-system began to approximate an undisturbed ecosystem where only slight changes in the understorey vegetation were observed.

在8公里处生态系统开始变成一个近似于无法干扰的生态系统，在下层植被仅可以观察到轻微的变化。

Tropical forest is wetter and usually supports only knee-high fires that spread slowly through the understorey.

热带森林比较潮湿，通常情况下只允许膝盖高的火苗通过下层植物慢慢地蔓延。

Tropical forest is wetter and usually supports only knee-high fires that spread slowly through the understorey.

而热带森林通常较湿润，火通常只在及膝的森林底部进行。

The results showed that the species richness,the speciesdiversity and its biomass of understorey vegetation decreased with the stand age in-creasing.There was the most significant negative-linear relationship between thiskind of changes and age.It is possible that the certain shading condition may benefit to understorey growing better.The richness,diversity index and biomass of thevegetation in eucalypt plantation decreased with CPR increasing,however,after ro-tating by watermelon one rotation,the richness,the diversity index and biomass ofunderstorey in CP stand increased,this result will provide the possibility of therestoration and reestablishment of vegetation in eucalypt plantations.The nutrientstorage of understorey decreased in accord with the productivity decreased withCPR increasing,this is the result which the stand enviroment became worse and thestand stratum competed with the vegetation for the water and fertility of soil.

结果表明，随着年龄的增长，桉树林下植被物种丰富度降低，多样性减少，生物量下降，这种变化趋势与年龄存在极显著的负线性关系；随着造林密度的增加物种丰富度降低，多样性也下降，但林下植被生物量尚有增加，可能是一定程度的庇荫有利于桉树林下植被的生长；随连栽代次的增加，桉树林下植被丰富度降低，多样性指数下降，生物量减少；但在轮作一茬西瓜后的林地，物种丰富度提高，多样性指数升高，生物量增加，为桉树林下植被的恢复与重建提供了可能性；随连栽代次增加，林下植被养分总量逐代下降，与生产力下降一致，这是林分环境恶化后上层乔木和林下植被对水肥竞争的结果。
