抚育间伐是从幼林郁闭起至主伐前的这段时间内,在森林中定期而重复地伐除部分林木,其目的是为留存林木创造良好的环境,使它们更快更好地生长;同时,还可以获得一部分木材。所以,抚育伐既是培育森林的一种措施,又是获得木材的一种手段。在生产实践中,不仅要考虑到间伐的技术效果,更要考虑到间伐的经济效果;并使这两者有机地结合起来,做到技术上先进,生产上可行,经济上合理。本文仅就吉林省人工落叶松林的不同间伐强度, Tending thinning is carried out regularly and repeatedly in the forest during the period from the closure of the young forest to the main logging period. The aim is to create a favorable environment for the preservation of trees so that they can grow faster and better; meanwhile, , You can also get some wood. Therefore, tending cutting is not only a measure to cultivate forests, but also a means to obtain timber. In production practice, we should not only consider the technical effect of thinning, but also take into account the economical effect of thinning. They should be organically integrated to make them technologically advanced, feasible in production and economically reasonable. This paper only on artificial deforestation in Jilin Province different thinning intensity,
