采用标准地观测的方法，研究了带状采伐栽植阔叶树后油松（ Pinus tabulaeformis）人工林天然更新的特点和效果。结果表明：带状采伐栽植阔叶树后，油松人工林天然更新效果受立地条件影响，阳坡不能更新或更新幼树极少。油松窄带状采伐栽植山杏（ Prunus sibirica），油松保留带内油松天然更新幼树达3500株/hm2；山杏林带内油松更新幼树约2500株/hm2，与山杏形成了混交林。油松窄带状采伐栽植黄栌（ Cotinus coggygria var．pu-bescens），油松保留带、黄栌林带油松更新幼树株数均达到了天然更新标准；在有一定数量前更幼树的前提下，油松宽带状采伐栽植刺槐（ Robinia pseudoacacia）、山杏等阔叶树后天然更新良好，阔叶树带内形成了稳定的针阔混交异龄林。

We studied the effects of planting broadleaf tree species after strip cutting on natural regeneration of Pinus tabulaefor-mis plantation by employing the observation of sample plots .The site condition has significant effects on natural regenera-tion of Pinus tabulaeformis, and there are no or very few saplings on sunny slope .In the trial of planting Prunus sibirica af-ter narrow strip cutting, the number of Pinus tabulaeformis sapling is 3 500 N/hm2 at the leave strip, and that is 2 500 N/hm2 at the broadleaf tree strip .In the trial of planting Cotinus coggygria var.pubescens after narrow strip cutting , the num-ber of Pinus tabulaeformis sapling is up to the standard of natural regeneration at the leave strip and broadleaf tree strip .In planting Robinia pseudoacacia and Prunus sibirica plantations after broad strip cutting , the mixed uneven-aged forests are at the cutting strip.
