摘　　要：对东北东部山区的天然次生林群落中主要树木种群的生态位在多个资源维度上进行了测度和分析，并将ＰＣＡ技术运用于生态位的测度过程中．进行生态位研究有利于深入了解各主要树木种群的生物学和生态学特性及种间的相互关系，同时也有助于对次生林群落结构形成机制的深入分析与阐释．On the basis of multidimensional resource axes,the niches of main tree populations innatural secondarv forest community of eastern mountain area in Northeast China were measured andanalysed,and with PCA technique to the course of niche measurement.Through these studies, the eco-logical characteristics and their relationships among main tree populations in natural secondary forestcommunities were revealed deeply,the mechanism of secondary forest communities structure was alsoanalysed and explained deeply.
