| 摘 要： | 以长苞铁杉及其伴生树种在正常纯林和伴生树种为优势种组成的阔叶林中的优势度为环境容纳量，用重要值百分数求取种间竞争系数，采用Ｌotka-Volterra竞争方程研究长苞铁杉林的共优种群（长苞铁杉与其伴生树种）种间竞争关系，结果表明，平衡时，长苞铁杉及其伴生树上对优势度分别为７４．２２％和２５．７８％，说明长苞铁杉种群支配整个群落。

| Abstract: | In this paper,the percentages of important value of Tsuga longibracteata and its associated species are regarded as the measure of the competitive parameter,and the dominant degree of normal stands are regarded as their environmental capacity.The final results of competition of inter species are discussed with the Lotka Volterra equation of competition,which shows that the relative dominant degree of Tsuga longibracteata and its associated species are 74.22% and 25.78% respectively when reaching their balance.Here mixed trees can jointly dominate this community,and the whole community is controlled by Tsuga longibracteata population. |
