摘要 用Hegyi的单木竞争指数模型对不同演替阶段的四川大头茶群落内的四川大头茶种内、种间的竞争强度进行定量分析。结果表明:四川大头茶种内竞争较与其伴生树种间的竞争剧烈;竞争木对对象木(四川大头茶)的竞争强度与对象木的个体大小服从幂函数关系,竞争强度随着对象木个体的增大而减小; With the aid of Hegyis' single tree competition index model, we have quantitatively analysed the intraspecific and interspecific competition intensity of Gordonia acuminata at its different developing stages within its own community. The results ws have got show: the intraspecific competition of Gordonia acuminata is more intensive than interspecific competitions with other species of accompanying trees; The competition intensity of competitive tree against objective tree and the size of objective tree are subject to power function, and competition intensity decreases with the increase of the size of objective tree; apart from these, there is a obviously negative correlation between the growth speed of objective tree and competition index.
