以靖安县为研究对象,从作业级层次提出了杉木大径材的经营模式,在现有18地位指数以上的杉木林地选取目标树,然后通过合理的抚育间伐、林地施肥等后期集约经营管理措施,不断调整林分密度,使目标树保留密度为1?200株/hm2左右,最终培育成大径材。这对于指导南方集体林区县级开展森林经营,促进区域森林持续经营水平的提高具有指导意义。
Using Jing’an County as an example,this paper puts forward the sustainable management pattern of Chinese Fir for big-diameter timber at the level of management for the first time. Goal trees of Chinese Fir in the forest land with site index 18 are selected and some measures such as reasonable tending thinning and forest fertilization used. Stand density is adjusted continuously to keep 1200 trees per hectare for reaching the goal of producing big-diameter timber. This paper provides some guidance for county-level forest management and improving forest management in collective forest areas in south China.
