摘要：调查紫金山南坡森林植被群落,分析北亚热带次生林的演替规律.结果表明:紫金山南坡不同海拔高度的森林群落在建群种的组成、层次结构上都存在有一定的差异,其主要乔木的基盖度从山顶到山脚的整体趋势增大.在乔木树种的多样性指数上,山腰>山顶>山脚.虽然人工针叶林仍占有重要地位,但正处于明显的演替之中.以马尾松(Pinus masoniana)为优势的阳性针叶林已处于衰退境地,而以栓皮栎(Quercus variabilis)、枫香(Liquidambarformosana)为优势的天然次生落叶阔叶林正在迅速恢复,并成为森林群落的优势树种,樟树(Cinnamomumcomphora)、紫楠(Phoebe sheareri)等常绿阔叶树种的幼树在林中出现并发展起来.这显示出人工针叶林经针阔混交林、落叶阔叶林,逐渐向地带性植被落叶-常绿阔叶混交林方向演替.
Succession laws of secondary forest is analyzed in the northern part of subtropical region by means of survey data of forest vegetation community in the south slope of the Purple Mountain. The result shows that composition of dominant tree species and layer structure of the forest community change with the change of elevation, and the basal coverage of the dominating arbor trees increase from the peak to the foot in the south slope of the mountain. The arbor tree＇s diversity index of the middle of the Purple Mountain is more than the top and the foot. The artificial pine forest is still dominant element in part area of the Purple Mountain, but present vegetation of the Purple Mountain is also in an active stage of successional change. The light demanding coniferous forest stands such as Pinus masoniana has declined day by day. The natural secondary deciduous-latifolious forest stands such as Liquidarnbar formosana and Quercus variabilis are developing and becoming abundant species in the forest. The evergreen broad- leaved tree＇s young trees such as Cinnarnornum comphora and Phoebe sheareri are evidently increasing in the forest. All that shows the artificial coniferous forests succeede to coniferous and latifolious mixed forests, then to deciduous and latifolious forests, and gradually to zonal vegetation-deciduous and evergreen broad-leaved mixed forests.
