摘　　要：我国是世界上人工林面积最大的国家。近自然林是实现我国人工林经营由数量上的扩张转向生态系统服务的质量和效益提升的有效途径。本文结合婺源县生态林场人工林更新的实践经验,总结出阔叶树特别是乡土珍贵阔叶树造林成活率低是影响当前社会营造阔叶树特别是乡土珍贵阔叶树积极性的根本原因。介绍了人工林炼山更新、不炼山更新及近自然林业、近自然恢复、人工林近自然改造结果。在借鉴婺源县天然阔叶林天然更新、刨花楠天然更新的基础上,提出人工栽植阔叶树近自然恢复人工林采伐迹地的更新方法,并以婺源县生态林场人工栽植刨花楠近自然恢复杉木人工林采伐迹地为例,指出了人工栽植阔叶树近自然恢复人工林采伐迹地为人工纯林向乡土珍贵阔叶树近自然林的转变提供了简易有效的途径。China has the most large proportion of artificial forest in the world.Nature-approximate forestry is an effective way to change the management of artificial planting from simply quantity expansion to the increase of ecosystem ′s quality and efficiency.Based on the practical experience of artificial planting regeneration in Wuyuan Ecological Forest Farm,this paper summarized that the survival rate of broad-leaved trees was low,especially local precious broad-leaved trees,which was the fundamental reason that affected the enthusiasm of planting broad-leaved trees,especially local precious broad-leaved trees.This paper introduced the results of the regeneration of artificial forest refined mountain,the regeneration of unrefined mountain,the regeneration of nature-approximate forest,the restoration of nature-approximate forest and the natural transformation of artificial forest.Based on the natural regeneration of the natural broad-leaved forest and the natural regeneration of Machilus pauhoi in Wuyuan County,this paper put forward the regeneration method of planting the broad-leaved trees nature-approximate restoration of the the cutover land.Taking nature-approximate restoration of cutover fir forest land by artificial planting Machilus pauhoi in Wuyuan Ecological Forest Farm as an example,it gave a guidance to transform the entire artificial plantation to broad-leaved nature-approximate forest.
