| 摘 要： | 研究了重庆缙云山大面积分布的亚热带次生性针阔混交林林隙树木更替规律，预测了该类型林林隙演替趋势。结果表明：马尾松(Pinus massoniana)种群表现出强烈的相互更替模式，四川大头茶(Gordonia acuminata)、四川山矾(Symplocos setchuanensis)等常绿阔叶树种自我更替与相互更替两种模式共存；林隙现实树木更替过程不能维持群落现有组成；Markov转移矩阵分析表明未来林冠层组成中马尾松种群将失去优势地位，整个群落将由针阔混交林向常绿阔叶林方向演替。

| Abstract: | Gap phase replacement of trees was studied in a secondary conifer broad leaved mixed forest distributed widely in Jinyun Mountain, Chongqing and successional trends in gaps and forest type were predicted. The results show that while Pinus massoniana has an intense reciprocal replacement pattern, Gordonia acuminata,Symplocos setchuanensis and other evergreen broad leaved tree species display both self replacement and reciprocal replacement patterns. The current tree replacement process in gaps does not appear to act towards the maintenance of the current community composition. The analysis of Markov transition matrix shows that the Pinus massoniana population will lose its dominant position in the future composition of the forest canopy.The whole community is in a succession process from a conifer broad leaved mixed forest to an evergreen broad leaved forest. |
