根据我们对南岳广济寺森林群落的实地考察及其调查资料统计分析结果,发现该群落是一种尚未报道的新类型,即水丝梨+甜槠-尾叶山茶+花竹-蔓赤 车群丛(Association of Sycopsis sinensis+Castnopsis eyeri-Camellia caudata+Phyllostachys nidularia-Pellionia scabra)。该群落内有维管束植物69科116属149种;其属的区系是以热带性质成分为主,温带性质成分为辅,各占56.19％和43.81％;其种的区系成分以华夏、东亚、中国-日本和华东至华中等四种类型为主,同时本群落具有明显的华东至华中过渡交迭性质。在群落中木本植物和草本植物各占71.14％和28.86％,草本植物中的多年生和一年生类型各占22.82％和6.04％。本群落可以明显划分为乔、灌、草三个层次,每个层次又可以进一步划分为三个亚层。这一群落是中亚热带东部典型常绿阔叶林北部植被地理亚带中的常绿阔叶林,在演替过程中,群落仍将保持以水丝梨为优势种的常绿阔叶林,但其亚优势种——甜槠将可能会被多脉青冈、中华石楠、长叶石栎取代。
According to our field investigation of Guangji Temple in Nanyue county and the statistical analysis of survey data, we found that the community is a new type that has not yet been reported, namely, Association of Sycopsis sinensis + Castnopsis eyeri-Camellia caudata + Phyllostachys nidularia-Pellionia scabra. There are 149 families, 116 genera and 69 families of vascular plants in the community. The flora of the genus is mainly composed of tropical species and temperate species, accounting for 56.19% and 43.81% of the total, respectively. The species composition of the species is Huaxia, East Asia, China - Japan and East China to Central China, and the community has obvious overlapping transition from East China to Central China. In the community, woody plants and herbaceous plants each accounted for 71.14% and 28.86%, while herbs and perennials accounted for 22.82% and 6.04% respectively. The community can be clearly divided into Joe, irrigation, grass three levels, each level can be further divided into three sub-layer. This community is an evergreen broad-leaved forest in the geographical subtropical zone of northern typical evergreen broad-leaved forest in the eastern subtropics. In the succession process, the community will maintain the evergreen broad-leaved forest dominated by hydroponic pear, However, its subdominant species - sweet 槠 will likely be replaced by Cycloccus alatae, Chinese heather, Lithocarpus longan.
