摘要
根据实地考察及其研究结果,南岳上封寺森林群落是一种尚未报道过的新类型,即长叶石栎+多脉青冈-尾叶山茶-求米草群丛(Association ofLithocarpus henryi+ Cyclobalanopsis multinervis—Camellia cauaata—Oplismeatus undulatifolius)。该群落内有维管束植物44科、64属、73种;其属的区系性质是以温带性质占多数,温带、热带性质成分各计53.45％和46.55％;种的区系成分以华夏、东亚和华东-华中三种分布类型为主,分别占总数的25.35％、22.53％和12.68％,群落区系具有明显的华东-华中区系的过渡交汇性质。在群落中,木本植物和草本植物各占73.87％和26.03％,其中草本植物中,多年生占20.55％。该群落明显分为乔、灌、草三层,其中乔木层又可分为二个亚层,它是典型的中亚热带东部常绿阔叶林北部植被地理亚带中的常绿阔叶林。在群落演替过程中,它仍将保持常绿阔叶林性质,但其优势种可能会被尾叶山茶、多脉青冈取代。
According to the results of the investigation and research of the forest community in Shangfeng Temple of Nanyue, Hunan province, this community is a new type which hasn't been reported;i. e. Association of Lithocarpus henryi+Cyclobalanopsis multinervis - Camellia caudata - Oplismenus undulati-folius. The community has 73 species ,64 genera and 44 families to belong to vascular plant. The temperate element of the flo ristic genera in community occupies 53. 45% of the total,but the tropical one 46. 55%. The floristic elements of species in the community are mainly Cathaysan,East Aisa and East China -Central China which occupy 25. 35%, 22. 53% and 12. 68% of the total respectively. It's very obvious that the floistic elements of East China and Central China cross at the species of the community in Shanfeng Temple of Nanyue. The wood plant in the com munity occupies 73. 97% of the total,but herb plant 26. 03% of which the perennical plant occupies 20. 55% of the total. The community can be div ided the arbor layer which can be divided two sublayer,shrub layer and herb layer,it is the Evergreen Broad - leaved Forest in North Sub- zone of Evergreen Broad -leaved Forest of the central subtropical of China. The community still keep the Evergreen Broad- leaved Forest, but its dominant species i. e. Lithocarpus henryi will probably replaced by Camellia caudata or Cyclobalanopsis multivervis and so on .
