摘要
本研究采用Ｌｏｔｋａ－Ｖｏｌｔｅｒｒａ竞争方程研究格氏栲林的共优种群（格氏栲、木荷）的竞争．用重要值百分数求取种间竞争系数，以优势种群在正常纯林中的优势度为其容纳量，结果表明：平衡时，格氏栲、木荷相对优势度分别为９４．３６％、５．６４％，即格氏栲林仍将由格氏栲、木荷两种种群共优组成。
In this paper,the percentages of important value of C.kawakamii and S.superbu are regarded as the measure of the competitive coefficience,and the dominant degree of normal stands are regarded as their environment capacity,then competition of this two species are discussed With the Lotka-Volterra equation.The results show that the relative dominance of C.kawkamii and S.superba are 94.36% and 5.64% respectively when reaching their balance.Here two species can jointly dominate this community,and the whole community is controlled by C.kawakamii population
