| 摘 要： | 用Hegyi的单木竞争指数模型对天台山红脉钓樟的种内、种间的竞争强度进行定量分析。结果表明:红脉钓樟种内竞争较之与其伴生树种七子花间的竞争弱。红脉钓樟种内、种间竞争强度的大小顺序为:七子花>种内>苦枥木>青钱柳>江浙钓樟>红果钓樟>阔叶蜡瓣花>榔榆>尾叶樱>柳杉。竞争木对对象木的竞争强度与对象木的个体大小服从幂函数关系,竞争强度随对象木个体大小的增大而减小;竞争强度与对象木胸径大小呈极显著的负相关关系。

| Abstract: | The intraspecific and interspecific competition intensity in lindera rubronervia in Tiantai Mountain of Zhejiang Province is quantitatively analyzed by using Hegyi single tree competition index model. 1 he results show that intraspecific competition intensity in lindera rubronervia is weaker than in Heptacodium miconioides , one of its associated tree species. The order of the intraspecific and interspecific competition intensity in Castanopsis eyrei is descending : Heptacodium miconioides. Fraximus, Cyclocarya paliurus , Lindera chienii, Lindera erythrocarpa , Corylopsis platypetala , Ul-mus parvijolia , Prunus dielsiana and Cryptomeria fortunei. The relationship of the competition intensity between the competitive tree,and the objective tree and the individual size of objective tree obeys power function rule and there is significant negative correlation between the competition intensity and the individual size of objective tree. |
