摘要
北亚热带地区的人工针叶纯林可以通过抚育间伐或者封山育林等措施大大加快其向着该地区的顶级群落方向演替。该地区几种典型群落的乔木层生物多样性指数大小依次为:针阔混交林>>常绿阔叶纯林>马尾松纯林(郁0.5)>马尾松纯林(CK组)>杉木纯林(修枝)>杉木纯林(间伐10%);灌木层生物多样性指数大小排序为:马尾松纯林(CK组)>杉木纯林(间伐10%)>杉木纯林(修枝)>常绿阔叶纯林>马尾松纯林(郁0.5)>针阔混交林。
The succession process from artificial pure coniferous forests to climax communities could be accelerated greatly by tending thinning or mountain closure for forest recovery in the northern subtropical region.The sequence of the tree layer diversity indexes of several typical forest communities is： Mixed coniferous and broadleaved forest Evergreen broadleaved pure forest Masson pine pure forest（crown density 0.5） Masson pine pure forest（CK group） Chinese fir pure forest（pruned） Chinese fir pure forest（thinned by 10%）.The sequence of shrub layer diversity indexes is： Masson pine pure forest（CK group） Chinese fir pure forest（thinned by 10%） Chinese fir pure forest（pruned） Evergreen broadleaved pure forest Masson pine pure forest（crown density 0.5） Mixed coniferous and broad leaved forest.
