摘要
通过大量的野外调查和室内分析，研究了红松种群天然更新及幼年生长与林分结构的关系．结果表明：林下红松的更新受上层林冠结构的制约，好的更新是同阔叶树的保护及稍大的干扰强度相联系，良好的红松幼苗幼树生长也是同阔叶树、稀疏的林冠、适宜的树木方位配置及稍大的干扰强度分不开的．
Through a great deal of field investigation and analysis,the relationship between natural regeneration and early growth of Korean pine and stand structure is studied.It is showed that low layer Korean pine regeneration is restricted by upper canopy structure .Excellent regeneration is relative with protection of broadleaved tree and suitable disturbance.Excellent growth of Korean pine seedling and sapling are also relative with broadleaved tree,rare canopy,suitable tree distribution pattern and suitable disturbance.
