本文從南方紅豆杉種群生態學的角度、主要應用數學生態學的方法探討南方紅豆杉種群的數量特徵，包括南方紅豆杉種群年齡結構、種群空間格局（探討分佈格局動態規律與生境相互關系） 、不同立地條件下種群優勢度增長趨勢、生態位寬度、生態位相似比例、生態位重疊、空間占據能力及種間競爭等，分析其目前現狀及瀕危原因，期望為南方紅豆杉野生資源的保護和擴大、營造人工林及可持續利用提供理論基礎，也為瀕危植物種群生態學的研究提供參考。 -
The growth dynamics of tree basal area of form. taxus chinensis var. mairei population in different altitude were discussed using the liu - logistic model, and the results showed that the altutide of 790 meters is more suitable to the survive of form. toms chinensis var. mairei population than 990 meters. plot sampling was selected and dynamic analysis was used to study the height structure of taxus chinensis var. mairei population, and the quadrate picture of height structure and the curve of survival rate were drew
運用改進模型對南方紅豆杉種群在不同海拔梯度的種群優勢度增長進行了探討，表明海拔790m處的南方紅豆杉具有較大的環境容納量，但增長速度不快，海拔990m處的南方紅豆杉種群環境容納量不高，但具有較大的增長速度，這可能與群落的發育階段不同有關，兩地海拔均為南方紅豆杉適宜的生長海拔高度，相比而言，海拔790m的珍稀瀕危植物南方紅豆杉種群數量特徵的研究高度更宜於南方紅豆杉種群的生長。 -
Taxus chinensis vsr. mairei population is very oblivious from seeding stage to mature tree stage. the patterns were consistant with the ecological and biological characteristics of form. taxus chinensis var. mairei which were valuable and rare and in severe danger. in this paper, logistic model and liu - logistic model were proposed to approach the growth dynamics of tree basal area of form. taxus chinensis var. mairei population
南方紅豆杉幼苗表現為較強的聚集分佈，除與種子的散布有關外，生境條件的差異是重要原因之? ，其它發育階段表現為明顯的隨機分佈，表明它在自然群落中分佈的概率很小，反映了南方紅豆杉珍稀瀕危的生態生物學特性和特徵。 -
The method of modified simplex was applied to optimize the models, and the fitting results show that liu - logistic model was more suitable than logistic model to the actual growth trend of form. taxus chinensis var. mairei population, and the highest growth rate of basal area was the tenth age class, namely the phase when breast diameter was 68 ~ 76 cm
以胸高斷面積代替種群生物量，分別採用logistic常規模型及劉金福提出的logistic改進模型對南方紅豆杉種群的增長動態進行研究，運用改進單純形法對模型進行優化，擬合結果表明改進模型比logistic常規模型更符合南方紅豆杉種群的增長趨勢，南方紅豆杉種群的最大增長速度出現在第10齡級，即胸徑為68 76cm時期。 -
The conidia of bipolaris species germinate principally from one or both polar cells with the basal germ tube originating close to the hilum and growing semiaxially and not germinate from the middle cells. the modes of the growth of the conidia on the conidiophores between species of bipolaris are similar and the minute differences between them are according to the different shape of the con idia
門）分生泡子萌發：本屬分生抱子從一端或兩端同時萌發一般沿著與分生抱子長軸相平行的方向，偶爾也與分生抱子長軸相垂直的方向，但不從中間細胞萌發。 -

該系統以可視水稻生長模型系統為基礎，以水稻「旺壯重」栽培技術、一次性全層施肥技術、水稻全程化控工程等研究成果為知識中心，試圖覆蓋水稻全部栽培過程和方式，為水稻栽培管理決策提供優化方案。 -
So evidence of sustained rapid growth, even into late juvenile and subadult stages, implies that the animals in question had relatively high basal metabolic rates
所以，即使進入幼年晚期與亞成體階段，仍持續快速生長的證據，暗示這些動物具有相對高的基礎代謝率。 -
3 the influence of water on vegetation growth : ( 1 ) soil water shortage refrains the height, basal diameter and stock of trees
3土壤水分對林分生長的影響： （ 1 ）土壤水分虧缺嚴重製約著樹高、胸徑和材積的生長。 -
Initial growth of crop stands can be easily obtained by an increase of planting density or by application of increased level of basal fertilizers
