  “herbage cover”译为未确定词的双语例句
     We found that slope location and water were main impacts on habitat selection of masked palm civets in spring, also canopy cover, the distance to roads, herbage cover, vegetation, the distance to residents and slope direction were included in it.

     The conclusions were as follows: (1) With the decrease of herbage cover on land surface, the correlation between soil erosion and runoff be-came small and the correlation between intensity and quantity of rainfall became large.
     结果表明:(1)随着地表草本植物覆盖率的降低,径流量与土壤侵蚀量的关联度愈来愈小,而雨强、雨量与其关联性却愈来愈大;

     (2) Squirrels did not like to utilize the micro-habitat in original Korean pine forest with a low slope degree,high density of fallen logs and stumps,high herbage cover and an abundance of pilfering animals(Ei<-0.2),and they show dislike for a shaded slope(Ei=-0.5368). This kind of selectivity of microhabitat utilization for hoarding behavior of squirrels play an important role in the Korean pine seedling spatial pattern.
     而对坡度小于5°、基质为霉菌土、倒木和枯立木密度较高(大于5个)、草本盖度较高、盗食动物活动中等(花鼠Eutamias sibiricus为主要盗食动物)的原始红松林生境表现出较强的负选择性(Ei<-0.2),对阴坡表现出强烈的回避性(Ei=-0.5368)。

With the method of grey correlation analysis, the authors quantitatively conducted a study on the correlation between soil erosion and hydrodynamic factors including precipitation, rainfall intensity and runoff in gran-ite area in southern China under different herbage coverage conditions. The conclusions were as follows: (1) With the decrease of herbage cover on land surface, the correlation between soil erosion and runoff be-came small and the correlation between intensity and quantity of rainfall became...

With the method of grey correlation analysis, the authors quantitatively conducted a study on the correlation between soil erosion and hydrodynamic factors including precipitation, rainfall intensity and runoff in gran-ite area in southern China under different herbage coverage conditions. The conclusions were as follows: (1) With the decrease of herbage cover on land surface, the correlation between soil erosion and runoff be-came small and the correlation between intensity and quantity of rainfall became large. (2) Under condition of bare surface land, main factor influencing soil erosion was not runoff but the intensity of rainfall. (3) Comparing with the quantity, the rainfall intensity had closer correlation with soil erosion. Therefore, it would be more suitable to select the rainfall intensity to reflect the influence of precipitation on soil erosion.

采用灰关联分析法定量地研究了华南花岗岩地区不同草本植物覆盖率条件下水动力因子(雨量、雨强、径流量)与土壤侵蚀量之间的关联程度。结果表明:(1)随着地表草本植物覆盖率的降低,径流量与土壤侵蚀量的关联度愈来愈小,而雨强、雨量与其关联性却愈来愈大;(2)当地表全裸露时,影响土壤侵蚀的主要因子是雨强,而不是一般认为的径流量:(3)与雨量相比,雨强和土壤侵蚀量之间有更密切的关联性,选择雨强来反映降雨对土壤侵蚀的影响更合适。

Analyses were made to the structure of the artificial herbaceous vegetation community at Shapotou sand-fixation site in the Tenggeli desert. It was shown that the sand-fixing vegetation established before 1960 had reached its subclimax. The indices of vegetation diversity and evenness were relatively high while the index of dominance was low. The major elements of the herbaceous layer were Eragrostis poaeoides, Bassia dasyphylla, Corispermum sp., Chloris virgata, Setaria viridis and others. After disturbances...

Analyses were made to the structure of the artificial herbaceous vegetation community at Shapotou sand-fixation site in the Tenggeli desert. It was shown that the sand-fixing vegetation established before 1960 had reached its subclimax. The indices of vegetation diversity and evenness were relatively high while the index of dominance was low. The major elements of the herbaceous layer were Eragrostis poaeoides, Bassia dasyphylla, Corispermum sp., Chloris virgata, Setaria viridis and others. After disturbances brought to the herbage-covered surface of sands, the community would restart a succession which starts from a different initial state, depending on the time length of the original established vegetation and the degree of disturbance, but ends up with a same final state.

对腾格里沙漠沙坡头人工固沙区草本植物带群落的结构组成进行了分析,结果表明,60年代以前的固沙植被区已进入演替的亚顶极群落,群落多样性、均匀度值均达相对最大,优势度最低。草本层片的种类组成以小画眉草(Erogrostispoaeoides)和雾冰黎(Basiadasyphyla)为主,伴生虫实(Corispermumsp.)、虎尾草(Chlorisvir-gata)和狗尾草(Setariaviridis)等的一年生草本。固沙区受到扰动(沙面被破坏)后因其固沙年限和干扰程度的不同,群落将在原基础上开始其初始状态不同而终局相同的演替历程。

The results showed that planting herbages as cover crops is an effective approach for building better orchard soils.Under herbage covers,the soil granules (μ>1.0mm) was 10.2%~12.2% higher than CK,an increase of 60.4%~72.2% than the original;the soil volume weight decreased 0.05~0.13g/cm 3,4.2%~10.0% lower than CK;the soil porosity was 2.5%~5.5% higher than CK,an increase of 4.6%~10.9% than the orginal percent;the soil organic matter was 0.19% ~0.79% higher than CK,an increase of 24.4%~73.1% than...
