摘要
用重要值百分数求取种间竞争系数,以优势种群在纯林中的优势度为其容纳量,采用Lotka-Volterra竞争方程探讨武夷山黄山松林的4种优势种群(黄山松、吊钟花、南方铁杉、豆梨)的竞争格局。结果表明:平衡时,黄山松、吊钟花、南方铁杉、豆梨相对优势度分别为72.01%、0.16%、26.09%、1.74%,表明黄山松和南方铁杉将占据主林冠层。
In this paper, the percentages measure of the competitive coefficient, and the of important value of Pinus tawanensis, are regarded as the dominant degree of normal stands is regarded as the environment capacity, then the competitive pattern of four species is discussed with the Lotka - Volterra equation. The results show that the relative dominant degrees of them are 72.01% , 0. 16% , 26.09% and 1.74% , respectively when reaching their balance, and the whole community is controlled by Pinus tawanensis and Tsuga tchekiangensis Flous populations.
