结构调控对人工用材林生长及生理生态过程影响研究进展

Effect of Structure Regulation on Growth and Physiological Ecological Process of Artificial Timber Forests

结构调控是人工用材林培育过程中的关键技术,主要包括通过间伐进行密度调控以及通过修枝进行树体管理。间伐与修枝作为2项重要的结构调控措施,广泛应用于人工用材林的培育与管理中,能够有效改善林分结构、促进林木生长并提高出材品质,对用材林产量与质量的提升具有重要意义。文中从冠层结构、生长、干形材质等方面综述目前国内外人工用材林结构调控的研究进展,阐述分析了结构调控在生理生态过程上的作用机理,并从间伐与修枝耦合效果、结构调控作用机理分析、结构调控模型构建等方面对未来开展人工用材林结构调控理论与技术创新进行了展望。

Structural regulation is a key technology in the cultivation of artificial timber forests,which is focused on density regulation through thinning and tree management through pruning.As two important structural regulation measures,thinning and pruning are widely used in the cultivation and management of artificial timber forests.They can effectively improve the stand structure,promote the growth of trees and improve the quality of timber,which is of great significance to improve the yield and quality of timber forests.This paper reviews the current research progress in the structural regulation of artificial timber forests at home and abroad from the aspects of canopy structure,growth,stem form and wood properties,and analyzes the working mechanism of structural regulation on physiological and ecological processes.In addition,the theory and technology innovation of structural regulation of artificial timber forests in the future is discussed in terms of the coupling effect of thinning and pruning,the analysis of working mechanism of structural regulation,and the construction of structural regulation model.
