摘要
近自然林业是一种尊重森林生态系统自身规律,并强调人为干预的林业生产活动,最终实现生产可持续和生态可持续。目标树作业是一种通过降低邻木冠层竞争、增加目标树生长空间来提高单木质量的营林技术,目标树作业是一种特殊的抚育间伐作业。文中从目标树单株经营,目标树的保留空间、修枝,干扰木伐除,目标树收获伐,人工辅助天然更新等方面阐述了目标树经营体系在近自然林业中的应用,并对目标树经营的优势以及目标树经营中受空间结构和垂直结构的影响进行了分析。
Near-natural forestry is a kind of forestry production activity that respects the laws of forest ecosystem and emphasizes human intervention,so as to finally realize production and ecological sustainability.Target tree operation is a kind of forest management technology to improve the quality of single trees by reducing the canopy competition of adjacent trees and increasing the growth space of target trees,which is a special tending thinning operation.This paper expounded the application of target tree management system in near-natural forestry from the aspects of single tree management,reserved space and pruning,removal of interfering trees,harvest cutting of target tree,and artificial assisted natural regeneration,as well as analyzed the advantages of target tree management and the influence of spatial structure and vertical structure on target tree management.
