The anatomical structure of the aerial adventitious roots of taxus chinensis var . mairei . was investigated in this paper 摘要对自然状态下南方红豆杉茎干向下萌生的气生不定根进行解剖学观察。
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 本文从南方红豆杉种群生态学的角度、主要应用数学生态学的方法探讨南方红豆杉种群的数量特征，包括南方红豆杉种群年龄结构、种群空间格局(探讨分布格局动态规律与生境相互关系) 、不同立地条件下种群优势度增长趋势、生态位宽度、生态位相似比例、生态位重叠、空间占据能力及种间竞争等，分析其目前现状及濒危原因，期望为南方红豆杉野生资源的保护和扩大、营造人工林及可持续利用提供理论基础，也为濒危植物种群生态学的研究提供参考。
The seeding accounted for 91 . 48 % of total number , and the mature tree of h : 5 ~ 7m class for 227 % whose density was just next to the seeding class . the results of intraspecific and interspecific competion formed the different individual height of taxus chinensis var . mairei population . the fractal dimension of taxus chinensis vsr . mairei were calculated on three indices : crown breath , base area , volume 分析南方红豆杉种群高度结构变化的原因认为，种间和种内对资源的竞争是引起其种群结梅粼七的主要原因，随着高度增长，物种间不唯琳内对生存空间的竞争加剧，形成南方红豆杉种群世代不同大， j 、个体的高度结构。
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 运用改进模型对南方红豆杉种群在不同海拔梯度的种群优势度增长进行了探讨，表明海拔790m处的南方红豆杉具有较大的环境容纳量，但增长速度不快，海拔990m处的南方红豆杉种群环境容纳量不高，但具有较大的增长速度，这可能与群落的发育阶段不同有关，两地海拔均为南方红豆杉适宜的生长海拔高度，相比而言，海拔790m的珍稀濒危植物南方红豆杉种群数量特征的研究高度更宜于南方红豆杉种群的生长。
The spectral analysis of the population showed that there was a marked regularity of periodic in the process of natural regeneration of taxus chinensis var . mairei , and it availed to the stabilazation of form . taxus chinensis var . mairei population . this paper presents the spatial distribution pattern and dynamics of form 南方红豆杉种群固有的生态生理特征决定了其生命表和存活曲线的类型，从种群发展的角度来看，早期较高的死亡率严重限制了南方红豆杉种群的扩展，是南方红豆杉濒危的重要原因。
Taxus chinensis var . mairei population in form . taxus chinensis var . mairei community using six aggregate indices ( c , i , i m , pai , ca , ) , then analyze the causes of evolved pattern . the results indicated that the distribution pattern of seedling were all clumped in every plot , however , the distribution patterns of sapling , media tree and mature tree were mostly random . the trend of diffuse of form )回归分析法研究了南方红豆杉林中南方红豆杉幼苗、幼树、中龄树和成树的分布格局及动态，并分析格局形成原因，结果表明，各样地南方红豆杉种群幼苗均成聚集分布，幼树的分布格局偏向于随机分布，而中龄树与成树则为随机分布，从幼苗到成树，随机扩散的趋势十分明显。
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 南方红豆杉幼苗表现为较强的聚集分布，除与种子的散布有关外，生境条件的差异是重要原因之? ，其它发育阶段表现为明显的随机分布，表明它在自然群落中分布的概率很小，反映了南方红豆杉珍稀濒危的生态生物学特性和特征。
The aesculus chinensis , euptelea pleiospermum , cercidiphyllum japonicum , taxus chinensis , picea brachytyla arid emmenopterys henryi oliv compose and stand structure of were studied , and the comparability matrix among those main woods distribution ere studied , and the protection propagation countermeasures were put forward , which are important for researching and protecting these rare woods in funiu mountain natural reserve 经调查，基本摸清了国家保护植物七叶树林、领春木树林、连香树林、红豆杉树林、云杉树林、香果树林6种珍稀树种林分的组成与结构，研究了主要林分之间的相似性矩阵，同时提出了保护繁育对策，对开展研究和保护珍稀树种具有重要意义。
