摘要
以米槠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竞争方程研究米槠林的共优种群(米槠与其伴生树种)种间竞争关系。结果表明平衡时,米槠与其伴生树种相对优势度分别为56.84%和43.16%,说明未来米槠仍将处于支配地位。
In this paper, the percentages of importance value of eastanopsis cadesii 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 - Voherra equation , which show that the relative dominant drgree of castanopsis cadesii and its associated species is 56.84% and 43.16% respectively when reaching their balance. This soggest that these trees can be coexisted in this community. But the community is dominated significantly by castanopsis carlesii population.
