摘  要：
通过对贵阳高坡南方铁杉群落组成、外貌、结构和种群动态的调查分析表明,该群落组成成分多样,具有10种植物属的分布区类型,其中热带成分占32.5%,温带成分占60%,地理成分由温带向热带过渡明显。南方铁杉在群落中占优势,重要值达143.88,群落生活型以高位芽植物为主,但缺乏大高位芽植物,具有中亚热带冷湿生境的群落结构特征。对种群动态的分析显示,南方铁杉径级呈不连续分布,群落难于维持持久稳定,提出了保护南方铁杉群落的措施。

摘  要：
The paper discussed the composition,appearance,structure and population dynamics of Tsuga chinesis var.tchekiangensison Gaopo in Guiyang.The results showed that the composition elements are diversified which posses 10 distribution types of plant genera.In those types,the tropical elements account for 32.5% and the temperate elements account for 60%,the geographical element transition from tropics to temperate is obvious.T.chinesis is dominant in the community,its important value is as high as 143.88.The phanerophyte predominate in the community,but the big phanerophyte is in shortage,the community displays the characteristics of the cold and wet habit in the mid subtropics.It is shown from the analysis of the population dynamics that the size class are not continuous distribution and the community is hard to maintain its steady for long.The effective methods are suggested in order to protect community of Tsuga chinesis.
