摘　　要：　植物种群之间的生态位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。采用定量分析方法,对武夷山米储林群落12个主要种群生态位(包括生态位宽度、生态位相似性比例、生态位重叠)进行了测定。结果表明:组成米槠林群落的优势种群绝大多数为广生态位,种群之间关系复杂,对资源具有一定的共享性。In this study, the niche characteristics of 12 main tree populations in Castanopsis carlessii forest have been analyzed by quantitative method at the nature reserve of Wuyi Mountains, including niche breadth, niche proportional similarity and niche overlap. The result shows that the vast majority of the main tree populations in the Castanopsis carlessii forest are of broad niche; that the relation among the species is very complex; and that many species share the same resources. The niche proportional similarity and the niche overlap index reflect the niche characteristics of the evergreen broadleaf trees in subtropical forest.
