| 摘 要： | 在福建省明溪县闽楠保护小区内以闽楠及其伴生树种在正常林分和伴生树种为优势种组成的阔叶林分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竞争方程研究闽楠的共优种群(闽楠及其伴生树种)种间竞争关系 结果表明平衡时,闽楠及其伴生树种相对优势分别为76 85%和23 15%, 说明闽楠种群在天然林中群落中处于支配地位

| Abstract: | The percentages of importance value of Phoebe bournei and its associated species were regarded as the measure of the competitive parameter ,and the dominant degree of normal stands were regarded as their environmental capacity.The final results of competition of inter-species were discussed with the Lotka-Volterra equation of competition ,which showed that the relative dominant degree of Phoebe bournei and its associated species is 76.85% and 25.15% respectively when reaching their balance .Here mixed trees can jointly dominate this community, and the whole community is controlled by Phoebe bournei population. |
