摘　　要：研究以“十四五”全国珍稀林木培育实施方案为依据,根据东北森工林区的树种特性和立地条件,设计该地区稀有林木定向培育模式,科学选择树种和优化伴生树种,并合理控制初植密度。选择合理提质培优的抚育方式,按照改造培育的补植技术要求,开展林下补植、人工促进天然更新和间伐修复等经营活动。通过稀有林木培育对生态与社会影响研究,有助于加快稀有林木的培育进程和提升品质。Based on the“14th Five Year Plan”national rare tree cultivation implementation plan,this study designed a targeted cultivation mode for rare trees in the Northeast Forest Industry Forest Area based on the characteristics of tree species and site conditions.The tree species and optimized companion tree species were scientifically selected,and the initial planting density was reasonably controlled.A reasonable nurturing method for improving quality and quality was selected,and the replanting technology requirements for transformation and cultivation were fllowed,We have carried out business activities such as understory replanting,arificial promotion of natural regeneration,and thinning and restoration.This article studies the ecological and social impacts of rare tree cultivation,which helps to accelerate the cultivation process and improve the quality of rare trees.
