摘要：采伐始终贯穿在全周期森林经营的每个阶段。建立与森林质量精准提升理念相适应的采伐管理模式,对森林资源的生长和长远发展具有重要的现实意义。国内外研究表明:采伐能够改善光照、减弱竞争、调整林分空间结构,进而促进保留木的生长;喜光树种和非成熟的小个体林木从减弱的竞争中获益更多;采伐还能改善林下土壤养分循环,促进天然更新,提高物种多样性;不合理、不及时的采伐可能会使林分错过最佳更新时间,也会减弱林分的抗逆能力,造成森林衰退。本文在综述采伐对森林发展的影响基础上,提出森林采伐管理和采伐方式的调整建议。
Cutting is carried out at every stage of forest management throughout the life cycle.It is of great practical significance for the growth and long-term development of forest resources to establish a cutting management model that is compatible with the concept of precise improvement of forest quality.Domestic and foreign research shows that cutting can improve light,reduce competition,adjust the spatial structure of stand,and promote the growth of retained wood;And light-loving and immature trees benefit more from reduced competition;In addition,cutting can improve soil nutrient cycling,promote natural regeneration and increase species diversity;Unreasonable and untimely cutting may make the stand miss the best renewal time,and also weaken the resilience of the stand,resulting in forest decline.On the basis of summarizing the effects of cutting on forest development,this paper puts forward some suggestions on the adjustment of cutting management and methods.
