摘　　要：以福建省三明市明溪县人工杉木林作为实验对象,在分析该林地基础条件之后,分别以不同林龄的人工杉木林地为基础进行相同力度的间伐,针对抚育间伐对不同林龄杉木林生物量的影响进行分析,得出不同的间伐实施时间产生的效果存在较大差异;选择适当的年龄进行抚育间伐,对于林地后期的生态形成具有明显的基础性作用,可以明显提高林区内的生物量。Taking the Artificial Cunninghamia lanceolata Forest in Mingxi County,Sanming City,Fujian Province as the experimental object,after analyzing the basic conditions of the forest land,the Artificial Cunninghamia lanceolata forest with different forest ages was thinned with the same intensity,and the influence of tending thinning on the biomass of Cunninghamia lanceolata forest with different forest ages was analyzed.It was concluded that there were great differences in the effects of different thinning implementation time;Choosing an appropriate age for tending and thinning plays an obvious basic role in the later ecological formation of forest land,and can significantly improve the biomass in the forest area.
