支提山突脉青冈天然林主要植物种群生态位研究

采用定量分析方法,计测突脉青冈天然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:组成突脉青冈天然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.

The Niche of Major Plant Population of Cyclobalanopsis. elevaticostata Natural Forest in Zhiti Mountain

With quantitative analyzing method, the paper explores and studies the niche breadth, the proportion of niche similarity and the niche overlap of main species of the vegetation layer in C.elevaticostata natural forests. The results show that the majority of the species in the C. elevaticostata natural forests are wide niche, the relation among the species is very complex and many species share in the resource. The proportion of niche similarity and the niche overlap index constitute the niche characteristics of the evergreen broad leaved woodland in subtropical forest.
