  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 research can offer some important references to the population ecology of endangerous plant, too. based on the dates of two different circumstances, two standard life tables of form. taais chinensis var. mcarei population are founded by mathematical technique according to premising with " space deducing time ", and the curves of survival rate, mortality rate and killing power were drew. the results showed both of the survival curves of population appeared to be a type of deevey - iii and the high mortality of seeding is one of the important reasons which caused taxus chinensis var. mairei to be endangered, which badly limited the enlargement of form. taxus chinensis var. mcarei population

    由於南方紅豆杉無解析木,因而以「空間推時間」 、 「橫向導縱向」方法,將林林依胸徑大小分級,以立木級結構代表年齡結構,採用分段勻滑技術,對兩個不同生境的南方紅豆杉種群編制特定時間生命表,繪制存活曲線,結果表明不同生境的南方紅豆杉種群的存活曲線均趨于deevey -型,兩地差異較小,幼苗死亡率極高,不同生境的幼苗死亡率均達到96以上。
