摘要
采用定量分析方法,计测天然甜槠林主要乔木树种的生态位宽度、生态位相似比例和生态位重叠值。结果表明:组成天然甜槠林的种群大多数为宽生态位,种群之间关系较复杂,对资源具有一定的共享性。种群之间的生态位相似比例和生态位重叠值反映了亚热带常绿阔叶林的生态特征。
Quantitative analysis method was used to determine the niche breadth, the proportion of niche similarity and the niche overlap value of main arbor species of C. eyrei natural forest. The results showed that the majority populations of C. eyrei natural forest had wide niche. The relationship among the populations was very complex. Many populations shared in the resources. The proportion of niche similarity and the niche overlap value indicated the niche characteristics of the evergreen broad-leaved woodland in subtropical forests.
