采用Hegyi提出的单木竞争指数模型对缙云山风灾迹地生态重建过程中主要优势种四川大头茶、川灰木、小叶栲、马尾松的种内种间竞争强度进行了定量分析 .结果表明 :1)对象木种内竞争较其伴生树种间的竞争剧烈 . 2 )竞争强度与对象木的胸径呈幂函数关系 . 3)对象木的生长速度与竞争指数之间有极显著的负相关关系 .
The single-tree competition index model proposed by Hegyi was used to quantitatively analyze the intraspecific competition intensities of the main dominant species, Szechwan green tea, Schima superba, Pinus elliottipes and Pinus massoniana during the ecological reconstruction of the Jinyun mountain winds. The results showed that: 1) The competition among target species was more intense than that between its associated species.2) The strength of competition showed a power function relationship with the DBH of target wood.3) There was a significant negative correlation between the growth rate of target species and competition index.
