摘要
对建溪流域常绿阔叶防护林群落的３０个主要优势乔木种群进行生态相似关系的研究。结果表明：组成建溪流域常绿阔叶防护林的乔木种群大部分为狭生态位，对资源的共享性不明显。种群之间的生态相似性比例和生态位重叠指数指标值反映了亚热带常绿阔叶林的生态特征。
The ecological relationships of 30 dominant tree species of evergreen broad leaved shelter forest in Jianxi River Valley in Fujian Province, were measured by quantitive analysis ,including niche breadth,niche proportional similarity and niche overlap.The results showed that the majority of the tree species of evergreen broad leaved shelter forests in Jianxi River Valley are narrow niche,and many species do not share intensity in the resource.The niche proportional similarity and niche overlap index reflect the niche characteristics of the evergreen broad leaved shelter in subtropical forest.
