low shrub 中文意思是什麼
low shrub
解釋
小灌木叢-
Unusually low bird density is due to many years of habitat degradation that has removed trees, eroded soils, and maintained grass - shrub cover over most of the island
不尋常的低鳥類密度是因為多年的生境惡化。島上大部分的地方只維持著草地灌木叢土壤流失和沒有樹木生長的狀態。 -
The fractal dimension of the quercus liaotungensis, the grassland and the shrub landscape elements in wutai mountain is rather low, which shows that the quercus liaotungensis, the grassland and the shrub landscape are interfered quite little by human activities. summarily, we can conclude that the wutai mountain is a preferable site for ecological tour, but the rather big difference between the areas of each landscape element, the quite low diversity, the rather high degree of dominance as well as the influence of human activities are all the problems to be solved in the future management of the wutai mountain
從五臺山各類景觀要素的分維研究中可以看出，各景觀要素的分維數普遍較低，說明各景觀要素的斑塊形狀較為簡單，受人為干擾較小；分維數較低的有遼東櫟林景觀、溫帶灌叢景觀、溫帶灌草叢及溫帶草原景觀和山地草甸景觀，這說明在該地區與其它植被景觀相比，遼東櫟林景觀、溫帶灌叢景觀、溫帶灌草叢及溫帶草原景觀和山地草甸景觀受人為活動的干擾較小，干擾程度低，天然狀態保持較好。 -
Species richness was generally low in all shrub communities
各類灌叢之間物種豐富度指數相差不大。 -
The species diversity index of the tree layer was a bit low, and the general trend was shrub layer > treelayer > herb layer
喬木層物種多樣性指數偏低，垂直結構各層次間物種多樣性大小依次為灌木層>喬木層>草本層。 -
The results shows that the community richness, species diversity indices and evenness of tree layer and shrub layer share the same order, of which is higher in pure limestone region than that of in pure dolomite region, but it reverse in herb layer ; the coefficient of similarity is considerably low between all plots, while species turnover rate is quite high among the plots and is higher in dolomite region than that of in limestone ; in different karst regions, karst processing leads to niches diversity characterized by special morphologies and special element geochamical features, and therefore affect the dynamic and features of plant communities
我們在最有代表性之一的貴州茂蘭喀斯特森林保護區選取純灰巖和純白雲巖兩種巖性的喀斯特環境，對其元素地球化學特徵及其中原生性植物群落的相異性和物種多樣性進行了對比，結果發現：不同巖性區域多樣性：喬木層和灌木層為純灰巖區純白雲巖區，草本層為純白雲巖區純灰巖區，總體上純灰巖區的高於純白雲巖區的；各樣地間的相似性系數都很低，相同巖性類型內的明顯高於不同巖性類型之間的相似度；物種周轉率高，且白雲巖區高於石灰巖區，種類組成差異明顯；喀斯特區可溶巖地球化學背景通過喀斯特作用導致特殊的地形條件與元素地球化學特徵，並引起局部小生境的分異從而影響植物群落特徵。 -
But for conifer community, since needle leaves decomposed very slowly, soil nutrient contents were rather low and even lower than those of former stages. on the contrary, natural communities consisted of broad - leaved species, including shrub community, commonly possessed high soil nutrient contents
但針葉林由於針葉較難分解，土壤綜合肥力很低，甚至低於前期階段;而由闊葉物種（包括灌木群落）組成的群落，土壤肥力普遍較高。
