查询词典 the canopy of the heavens

The distribution of branch angle was corelated to DINC of branch,the branch angle distributed in upper layer of canopy were generally small and with DINC increase the branch length of middle layer of canopy began to proglong,simultaneously,the weight of branch increased with branch diameter and length,hence,the branch angle of origin increased obviously and took the majority proportion.

着枝角的分布与着枝深度有密切的关系，着枝角度在树冠的上层时一般都较小，而随着树冠深度的增加，中层的枝条的枝长开始增大，枝条的重量随着基径和枝长在增大，着枝角度会明显增大，因此在这个范围内的分布最广，占了大多数。

However, it is difficulty to access to high forest canopy, which to some extent restricted the studies of epiphytes diversity in forest canopy.

Considering many biophysics processes such as the atmosphere,hydrology,plant leaf N content et al.a multiple layer,two-leaf canopy model for predicting of mass transportation and energy exchange between plant canopies and the atmosphere has developed after dividing the canopy height into three layers,and the sunlit and shaded leaf area index was computed respectively at different layers through introducing a foliage clumping index,it is important to distinguish the spatial light distribution and so leaf photsynthesis.

多层—双叶模型对冠层上方碳通量的模拟：综合考虑农田水、热因子及叶片氮含量的非线性垂直分布对碳、水循环的影响，将农田按植株高度分为上、中、下三层，并通过叶片集聚指数计算阴、阳叶面积以区分叶片的空间分布受光状态，建立了均匀农田与大气间物质输送和能量交换的多层—双叶模型，对农田冠层上方基于光合—呼吸的碳循环过程进行了模拟应用研究。

Treatments were as follows: fertilization during leaf-expansion period, fertilization during green-leaf period, and no fertilizer. Results showed that individual leaf area, thousand-leaf weight, and leaf distribution were relatively stable with little influence from fertilization. Fertilization during leaf-expansion compared to the green leaf period significantly increased leaf number, leaf weight per plant, and leaf area index. Fertilization during led-expansion also significantly increased the total weight of leaves corresponding to each branch. The 14th to the 17th branches had the largest number of leaves in the canopy with fertilization increasing the weight of each branch but not changing the center of the canopy.

结果表明：毛竹单叶面积、千叶质量和叶片分布受施肥的影响较小，是较为稳定的指标；展叶期施肥处理（处理1）能显著增加单株立竹的叶片数量，到7月底，其单株立竹叶片总质量和叶面积指数分别比绿叶期施肥（处理2）提高14.8%和13.7%，比不施肥提高27.6%和24.5%；冠层14~17档是单枝叶片数量最多的区域，施肥能增加各枝盘叶片的质量，但对林冠重心的分布无影响；单叶叶面积稳定后（6月），处理1的叶绿素测定值和光合速率显著高于处理2和对照，而处理2与对照间无显著差异。

Although forest canopy layer could prevent splash erosion effectively, clay was taken away by overland flow and run off easily, the erosion amount became less after removing the forest canopy and surface soil, while the splash erosion still produced in the surface layer; the splash function weakened after having water current, the starting particles were less than bareland, so removing the surface disturbed soil made the erosion amount and clay less, silty sand more than bareland, but unsteady, the wear and tear energy used by raindrop splash and current function for overcoming sediments separating and starting were comparatively large, sediments were very difficult to be started and transported, it explained that forest root systems could increase anti-erosion capability of forest vegetation, make rainfall-current system splash and export finer particles than bareland.

虽然林冠层能有效防止溅蚀的发生，但坡面流还是能带走粘粒部分，粘粒还是容易流失。去除林冠和表层土后，侵蚀量变得更少，但表层还是会被溅蚀，有水流后，溅蚀作用减弱，颗粒起动的比裸地的少，所以，去除表层扰动土后，侵蚀量更少，粉沙多，粘粒比裸地更少一些，但不稳定，雨滴击溅和水流作用用于克服泥沙分离起动损耗的能量较大，很难被起动输移，这说明森林植被根系的作用增加了林地植被的抗蚀力，使降雨一水流系统仅能溅起输出比裸地坡面更细小的泥沙颗粒。

A systematic study made in a clonal test forest in Linhai on timber properties of paper pulpwood of 20 new aigeiros clones of southern type shows that the fiber length in the trunk of these new clones gradually increases from the top to bottom,the fiber of the branches in the upper part of the canopy being shorter than that of the branches in the middle or lower part of the canopy

系统研究了来自浙江临海黑杨派南方型新无性系试验林 2 0个无性系的纸浆材主要木材性状。结果表明：黑杨派新无性系树干的纤维长度自上而下逐渐增长，树冠上部枝条的纤维较中、下部枝条为短

The soil nutrient content of spruce forest with small canopy density was lower, compared with that of spruce forest with great canopy density.

具体表现为郁闭度较大的云杉林立地土壤养分含量总体高于郁闭度小的云杉林。

For the forests with high canopy closure, both the annual carbon sequestration and the annual pollutant removal were high; while for those with lower canopy closure, these two characteristics were dependent on the structural complexity of the forests.

不同城市森林类型的碳密度与其结构密切相关，高郁闭度下固碳和污染物净化能力皆高，低郁闭度下固碳和污染物净化能力取决于其结构的复杂程度。

The rusults indicated that the temperature in forest was lower and the growth of ginseng was slower than out of forest, the yields were also lower; with the increase of ginseng age, the rate of net photosynthesis became higher; when the canopy density of forest reached to about 0.7～0.8, the net photosynthesis, hight, root weight, transpiration,chlorophyll conten of ginseng were higher than others, indicating that both lower and higher canopy density would reduce the rate of net photosynthesis of ginseng, and that the canpoy density of stand could be adjusted to satisfy the temperature and lighting for ginseng, and to provide the optimum ecology enviorment for the growth of ginseng.

结果表明，在生长季节内，林内温度低于林外温度，林下人参生长发育较差，产量较低；林分郁闭度为0.7~0.8时，人参的净光合速率、株高、单根重、叶绿素含量等指标较高；而郁闭度过高或过低都会影响人参生长发育；随着人参年龄的增加，净光合速率有逐渐升高的趋势。通过人为调节林分郁闭度的方式来满足人参对温度和光照因子的需求，为林下人参生长发育提供最适宜的生态环境。
