中文摘要	采用固定标准地观测方法,对朝阳半干旱地区油松天然更新人工促进措施进行了探讨,旨在为半干旱地区油松林的科学经营提供理论与技术依据.结果表明:问伐、带状采伐、带状采伐栽植山杏和整地措施可有效促进天然更新.对于31a生油松人工林,保留株数为225～375株·hm~(-2)的间伐强度更新效果较好,更新幼树株数为2630～3480株·hm~(-2),更新频率为78%～83%;带状采伐宽度以8～12m为宜,更新幼树株数为2604～4375株·hm~(-2),更新频率为67%～91%;通过带状采伐栽植阔叶树山杏,可逐渐把现有油松人工纯林向复层异龄混交林方向诱导.
英文摘要	In order to promote natural regeneration of Pinus tabulaeformis plantation,5 artificial measures were discussed by employing the observation of permanent plots. Results showed that some measures were very effective for promoting natural regeneration,such as thinning,strip cutting,planting broad-leaved trees after strip cutting,and site preparation. Suitable final crop stockings after thinning were from 225-375 stem·hm~(-2)for 31 years old plantation of Pinus tabulaeformis,in which sapling number was 2630-3480 stem·hm~(-2),and regeneration frequency was 78%-83%. 8~lm was best width of cutting belt,in which sapling number was 2604-4375 stem·hm~(-2),and regeneration frequency was 67%-91%. By means of the measure of planting broad-leaved trees after strip cutting,the large area of pure plantations of Pinus tabulaeformis could gradually become into mixed uneven-aged forests.
