摘要: 对深圳马峦山地区华南紫萁占优势的植物群落进行研究,结果表明:华南紫萁群落中共有维管植物48科69属82种,种类组成具有明显的南亚热带性质;年龄结构显示群落的主要优势种属于稳定型种群,群落总体处于稳定状态;群落的频度指数规律为A>B<C>D>E,与RaunKiaer频度定律、海南岛山地雨林优势种群的频度规律等不相符合;华南紫萁种群树高和个体数百分比显示,种群高度0.3~0.7 m植株占比例较大,种群处于旺盛发展期;物种多样性指数为SP=16.42,SW=4.56,均匀度指数为E=0.33,E′=0.83,群落物种多样性指数和均匀度指数均较高,接近典型南亚热带常绿阔叶林顶极群落类型。本研究揭示了华南紫萁野外生存状态,为该种的保护和利用提供了基础资料。

Abstract: According to the field investigation and analysis of the Osmunda vachellii populations and communities from Mount Maluanshan in Shenzhen,the results indicated that:82 species of vascular plants, belonging to 48 families and 69 genera were found in the O.vachellii community,the floristic components of community was with an south subtropical property; The analysis for the age structure of the community showed that the main dominant species were stable populations,but the frequence index of community was A>B<C>D>E,which was different from the Raunkiaer’s frequency law,and was also different from those of montane rainforest of Hainan island; The percentage of tree height and individual number from O.vachellii population showed that those with a tree height 0.3-0.7 meters occurred a higher proportion,indicating the populations was in a bloom of development period;and the Simpson and Shannon-Wiener index of diversity is 16.42 and 4.56,while the evenness index for E and E′ is 0.33 and 0.83, respectively,which indicated the diversity and evenness index is closed to those of the climax community from typical subtropical evergreen broad-leaved forest. The study reveals the natural survival state of O.vachellii and provides protection and utilization data for O.vachellii.
