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。
Taking Jing’an County as the research object, this paper put forward the operation mode of large-diameter fir timber from job level, selected the target tree in the existing fir land with 18 index above, and then through the later intensive management measures such as reasonable tending thinning and forest land fertilization , Continue to adjust the stand density, so that the target tree reserve density of about 1 200 plants / hm2 or so, eventually bred into large diameter timber. This is instructive for guiding the development of forest management at the county level in southern collective forests and promoting the sustainable management of the region’s forests.
