摘　　要：根据野外调查数据,运用Hegyi单木竞争指数模型,定量分析了长白山红松针阔混交林中红松的种内、种间竞争关系.结果表明:长白山红松针阔混交林内,红松的平均种内竞争强度为0.269 9,竞争强度随着红松林木径级的增大而减小.总体来说,红松的种内竞争强度高于种间竞争.Using Hegyirs competition index model for individual tree, intra-specific and inter-specific competitions of Pinus koraiensis broadleaf mixed forest in Changbai Mountains were analyzed. Data showed that intra-specific competition intensity for Pinus koraiensis was 0. 269 9, this was reduced with increased diameter classes. Intra-specific competition was much larger than inter-specific competition in Pinus koraiensis broadleaf mixed forest.
