herb layer
解釋
草本層-
Plants growing in the semi - fixed sand dunes, on the other hand, were less branchy with a larger number of first - year shoots which were longer, and grew faster ; their leaves were longer and wider with a low length / width ratio. the characteristics of the branching system and leaf dimensions of the plants in fixed sand dunes were rather intermediary between those of the above. the frequency distribution and their frequency in the herb layer the scrubs also varied with habitats
丘間低地的黃柳灌叢當年枝平均長度增加緩慢，短枝條的比例較高，當年枝枝長頻度分佈峰值偏左，葉片短而狹，長寬比大；與之相比，分佈於半固定沙丘的灌叢當年枝平均長度增加較快，長枝條比例較高，葉片長而寬，長寬比小；固定沙丘上的上述特徵大致介於二者之間。 -
The species richness and diversity index order of coniferous and broad - leaf forest and evergreen broad - leaf forest in different geology plots was as follows : shrub layer > herb layer > tree layer ; in shrub plots, the order was herb layer > shrub layer. in general jsw, jsi and ea index order was herb layer > shrub layer > ree layer. that indicated that the species of tree and shrub in karst area distributing is not even, and the species, which are dominant and adapt to the karst environment are cleaer

結果表明： （ 1 ）梅子湖森林植被樣地物種多樣性測度的結果，上述4種指標總體上表現出相同的變化趨勢。門）總體看來， 14個樣地的物種多樣性指數在群落不同層次的變化規律為：灌木層喬木層草本層。 （ 3 ）不同植被類型的物種多樣性特徵是：常綠闊葉林暖性針葉林。 -
The water - holding capacity of altinglia gracilipes, schima superba, fokienia hodginsii and cunninghamia lanceolata planted under cunninghamia lanceolata ecological public welfare forest was studied from forest canopy, shrub and herb layer, litter layer and soil layer
摘要分別從林冠層、林下植被層、凋落物層及土壤層對杉木人工生態公益林林冠下營造的細柄阿丁楓、木荷、建柏和杉木純林的持水功能進行了研究。 -
Root distribution and canopy structure parameters of s. godejevii in different sandy land habitats ( semi - fixed sand dunes, fixed sand dunes and inter - dunes low land ), as well as species composition and their frequency in the herb layer of the scrubs, were compared the results were as follows : the population hi the semi - fixed sand dunes had the most developed root systems, followed by he population in the fixed sand dunes, and that hi the inter - dunes low land was the last
為了更有效地利用這一重要植物資源，本文對分佈於渾善達克沙地三種不同沙地生境（半固定沙丘、固定沙丘、丘間低地）黃柳灌叢的根系分佈，冠層特徵進行了研究，同時測定了灌叢下草本層植物種類組成及頻度，結果表明：半固定沙丘上的黃柳根系最發達（根系分佈深，數量大） ，固定沙丘的黃柳明顯不及前者，而丘間低地的黃柳根系最不發達。 -
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，並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於草本層，且差異極顯著，群落均勻度差異顯著。 -
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。
