  1. Form. taxus chinensis var. mairei is protecting plant in the first class, which is a precious and endangering plant in china in this paper, the quantitative characterics of form. taxus chinensis vsr. mairei population including age structure, spatial distribution pattern, growth dynamics of tree basal area, niche characterics, fractal dimension and competition between specises were studied using methods of mathematics ecology from the angle of population ecology of form. taxus chinensis var. mairei, then the prent state and the endangering causes were analysed. this research offers gist to protecting and enlarging the crude resourse of form. taxus chinensis vsr. mairei population, afforesting plantation and sustainable utilize for us

    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。
  2. 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。
  3. 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。
  4. And through leslie matrix analysis, we deduced, except of the subpopulation at altitude 490m, the subpopulations of lilium tsingtauense will not die out if not been disturbed badly. we estimated the growth ability and resistance ability of both metapopulation and local population by use the method of quamitative analysis for population structura1 dynamics. the growth ability order is population l > population 2 > population 3 > population 5 > population 6 > metapopulation > population 4

    川叩iqu n了e ）復合種群研究摘要從種群年齡結構的穩定、衰退、增長概念出發，以種群結構參數為依據，運用加權法與條件概率乘法法則，定量椎導出衡量種群年齡結構及群落結構的動態指數，該方法克服了過去在植物種群結構動態比較評價中粗放的等級歸類劃分的缺陷，並能解決結構動態定量比較評價問題，因而認為有普遍使用的價值。
  5. The temporal and spatial dynamics of a single species metapopulation is modelled by a model. the stability of spatial distribution of the population and relationships between the stable patchy distribution and migration rates and finite rate of growth of subpopulations are also investigated. finally measures to boost the growth of total population are presented through the model and analysis of the model

    通過模型模擬了呈一般綴塊分佈的單種種群的時空動態.討論了種群空間分佈的穩定性及穩定綴塊分佈與種群在綴塊間遷移率和子種群增長率之間的關系，並由此提出了促進全局種群增長的措施
  6. In order to understand the nature of the ecologist ' s investigation ， we may think of the density - dependent effects on growth parameters as the “ signal ” ecologists are trying to isolate andinterpret ， one that tends to make the population increase from relatively low values or decrease from relatively high ones ， while the density - independent effects act to produce “ noise ” in the population dynamics

    為了能理解生態學家們所從事的研究的性質，我們可以把那些作用於增長參數的密度依賴效應視作生態學家們力圖將其分離並予以解釋的「信號」 ，正是這一信號傾向于使種群從相對較低的數值遞增，或從相對較高的數值遞減；而與此同時，那些密度獨立效應起到的作用則構成了種群動態變化中的「噪音」 。
