摘要
小兴安岭阔叶红松林(Pinus koraiensis)是地带性顶极植被。本文以黑龙江丰林国家级自然保护区阔叶红松林为研究对象,系统分析小兴安岭阔叶红松林林分类型分布的斑块和年龄特征、垂直分布特征,论证郁闭度对红松群落数量、幼林生长群落的影响,阐述不同林分类型对红松天然更新的影响、上层林冠抚育对红松幼树的影响、上层林冠抚育强度对红松生长的影响。结果证明:透光抚育为红松提供了良好的生长空间,上层抚育可显著提高林冠下红松幼树的高生长、地径生长和保存率,提出了小兴安岭阔叶红松林生态修复的策略。
The broad leaved-korean Pinus koraiensis mixed forest in Xiaoxing＇ an mountains is a zonal climax vegetation. In this paper, the broad leaved-korean Pinus koraiensis mixed forest in Fenglin Natural Reserve of Heilongjiang Province were investigated and the stand type, distribution patch, age features, and vertical distribution characters were studied. The author expounded the effect of crown density on the Pinus koraiensis quantity and young stand community, the effect of different forest types on natural regeneration, upper story thinning on the young trees, and the effect of thinning intension on the growth of Pinus koraiensis. Results showed that re- lease thinning provided excellent living space for Pinus koraiensis and significantly increased the height, base diameter, and survival rate. The ecological restoration strategy for broad leaved-korean Pinus koraiensis mixed forest in Xiaoxing＇ an mountains was then put forward.
