摘    要:用Hegyi的单木竞争指数模型对天山云杉种内竞争强度定量分析结果表明,种内竞争强度随着林木径级的增大而逐渐减小,当天山云杉胸高直径达到18~22cm以上时,竞争强度变化很小,部分指数随着龄级的变化呈现类似的变化规律。

关 键 词:天山云杉  种内竞争  单木竞争

Abstract:By using Hegyi's competition index model individual tree, interspecific competition in Picea schrenkiana forest in Tianshan mountain, were investigated. The results shows that intraspectific competition intensity of Picea schrenkiana reduced with increase in diameter scale of the trees. The changing of competition intensity was very small when the diameter grew to 18-22 cm.The competition changing with age showed the same rule.
Keywords:Picea schrenkiana  interspecific competition  induvidual tree competition
