摘要
采用样方法,对深圳市羊台山森林公园群落的种类组成及物种多样性等进行调查。结果表明,基于10 800 m2样地的羊台山次生林群落共有维管束植物148种,分属61科110属,群落的植物区系具有明显的热带性质。群落主要优势种为黧蒴、豺皮樟、银柴、杉木。群落不同层次物种丰富度指数、Simpson指数和Shannon-Wiener指数大小排序大致一致,为乔木层>灌木层>草本层,Pielou均匀度指数则为灌木层>草本层>乔木层。
Species composition and biological diversity were studied by plot method in Yangtaishan Forest Park, Shenzhen City. The resuhs showed that 148 species in 110 genera and 61 families of vascular plants were found in the 10 800 m^2 plot. The flora was characterized with obvious tropical nature. Castanopsisfissa, Litsea rotundifolia, Aporosa dioica and Cunninghamia lanceolata were the dominant species. Species richness, Simpson index and Shannon-Wiener index of each layer showed the same change trend, tree layer 〉 shrub layer 〉 herb layer. Pielou evenness index showed different trend, shrub layer 〉 herb layer 〉 tree layer.
