There was no significant difference of diversity index between the tree layer and the shrub layer 喬木層與灌木層之間多樣性各項指標總體無顯著差別。
Effects of selective cutting of different intensities on the tree layer structure and species diversity of evergreen broadleaved forest 擇伐作業對常綠闊葉林喬木層樹種結構及物種多樣性的影響
Effects of different intensities of artificial disturbance on tree layer of castanopsis carlesis forest using method of diversity measure 多樣性的測度方法探討不同人為干擾強度對米櫧林喬木層的影響
The vertical structure of each forest community were obvious and could be divided into tree layer , shrub layer , herbage layer and lianas 各群落垂直結構十分明顯,可分為喬木層、灌木層、草本層和層間植物。
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 complicated vertical structure could be divided into tree layer , shrub layer and herb layer , as well as a definite number of interstratum plants 群落垂直結構復雜,可分為喬木層、灌木層和草本層,并有一定數量的層間植物。
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 喬木層、灌木層的物種豐富度、物種多樣性指數均大于草本層,且差異極顯著,群落均勻度差異顯著。
The multilayer films instead of the single ito films were deposited to reduce the sheet resistance of films . the multilayer structure consisted of tree layers , ito / ag / ito 最后,制備了由商用ito膜、自制的單層ito膜和ito / ag / ito復合膜作為陽極的oled器件,并對三種oled器件的性能進行了比較。
There were 66 species in the community 3 ( castanopsis fargesii + schima superba - itea chinensis - maesa japonica community ) , and castanopsis fargesii and schima superba were the dominant species of tree layer , and itea chinensis and symplocos sumuntia were the dominant species of succession layer , and maesa japonica and ardisia japonica was the dominant species of regeneration layer 采用物種數、 m雌alef豐富度指數、 simpson和shannon一wiener多樣性指數、 simpson和shannon一wiener均勻度指數對黃茵嶺生態保護小區森林群落多樣性進行測定,結果表明該地區有較高的物種多樣性。
There were 71 species in the community 2 ( castanopsis fargesii - itea chlnensis - maesa japonica community ) , and castanopsis fargesii and itea chinensis were respectively the absolute dominant species of tree layer and succession layer , maesa japonica was the dominant species of regeneration layer 群落次生天然演替過程是以地帶性植被殼斗科、茶科、冬青科等物種為主。總體上黃茵嶺生態保護小區群落種子植物屬的分布類型是以熱帶分布成分占絕對優勢,種子植物以熱帶起源為主。
