| 摘 要： | 采用Hegyi提出的单木竞争指数模型,用竞争强度来指证竞争的激烈程度,结果表明:混交林中对象木青钱柳的种内、种间以及与整个林分的竞争强度均随径级的增大而减少,各径级的种内竞争强度远大于种间竞争强度 种内、种间以及整个林分的竞争强度与对象木的胸径服从幂函数CI=AD-B关系,用此模型来预测各径级的种内、种间竞争强度,拟合效果良好,当对象木胸径DHB≥26cm时,竞争强度变化很小,该研究为混交林的培育提供了适用的数量指标

| Abstract: | Using Hegyi′s competition index model of single tree,the intraspecific and interspecific competition intensity is quantitatively analyzed.The result shows: the intraspecific ,interspecific,entire stands competition intensity of objective tree Cyclocarya paliurua (Batal.)Ilinsk decreases with increase in diameter class and the intraspecific competition intensity is more intensive than interspecific competition intensity; The relation between competion intensity and individul size of objective tree in diameter class closely follow equation CI=AD~\{-B\}.When diameter size of objective tree≥26 cm,change of competition intensity is feeble.The study provides quantitative index for cultivation of mixed plantation. |
