间伐对杉木人工林地力的影响

Effect of Thinning on Land Capability of Chinese Fir Plantation

通过固定标准样地调查的方法,对杉木幼龄林、中龄林、成熟林进行间伐与不间伐试验。经过3年的实地调查发现,间伐可以促进杉木人工林林下植被的发育,进而有利于增强土壤肥力。

Experiments on thinning and nonthinning of young, middle and mature forests of Chinese firwere carried out by using fixed standard sample plot survey. After threeyear field investigation, it wasfound that thinning could promote the development of vegetation in Chinese fir plantation forest andfurther enhance soil fertility.
