摘　　要：为实现河北承德地区油松人工林的科学可持续发展,研究者采用标准观察法,对带状采伐后油松幼树人工林天然更新的特征和效果进行深入的分析与研究。结果表明,区域内油松幼树单棵活枝轮数与采伐带和保留带差异不明显。其中,保留带内活枝轮数变化幅度较小,而采伐带内树冠从上到下变化幅度较大。研究结果能为促进油松人工林的天然更新及相关林业机构拟定科学的森林经营方案提供有力数据支持。To realize the scientific and sustainable development of the pinus tabulaeformis plantation in Chengde of Hebei province,the characteristics and effects of the natural regeneration of the young pinus tabulaeformis plantation after strip cutting are deeply analyzed and studied by standardized observation method.The results indicate that there is no significant difference in the number of live branches per tree between the cutting zone and the reserve zone.Among them,the variational range of the number of living twigs in the reserve zone is small,but the variational range from top to bottom of the tree crown in the cutting zone is large.The results of this study can provide strong data support for promoting the natural regeneration of pinus tabulaeformis plantation and formulating the scientific forest management scheme for the relevant forestry institutions.
