摘要/Abstract

摘要： 以1 100 m²样地为研究基础,分析澳门青洲山假柿木姜子群落的种类组成、区系成分、外貌特征、群落结构以及多样性特征。结果表明,本群落有维管束植物47种,隶属于27科42属,热带分布种占绝对优势。群落外貌主要由单叶、中型叶,全缘的常绿高位芽植物决定。优势种径级显示:群落目前保持以假柿木姜子为优势种,翻白叶树与假苹婆为增长种群的格局。这3种主要种群呈集聚分布。整个群落Magarlef指数为4.9072,Shannon－Wiener指数0.8742,Simpson 指数1.1641和Pielou均匀度指数0.3024。多样性比较显示,该群落的物种多样性低于香港黄桐群落、鼎湖山厚壳桂群落及深圳南山区鸭脚木群落,可能与该地的岛屿性、优势种显著、外来种入侵等因素有关,应加强保护维持该群落的物种多样性。

Abstract: The characteristics and species diversity of the Litsea monopetala community in Ilha Verde Hill of Macao were studied. Based on data from 1100 m² plot. 47 species in 42 genera and 27 families of vascular plants were found. The floral composition of the community was divided into 9 areal types, and tropical elements predominated. The appearance of community was characterized by everygreen phanerophytes plants with mesophyll,entire and single leaf. The diameter classes of dominant populations implicated that the community dominated by Litsea monopetala may remain constant, while the amount of Terospermum heterophyllum and Sterculia lanceolata may increase. The horizontal spatial patterns of 3 dominance populations conform to aggregated distribution. The species diversity of the community is relatively poor with Magarlef index at 4.9072, Shannon－Wiener index at 0.8742, Simpson index at 1.1641 and Pielou index at 0.3024. Species diversity comparison with 3 communities of adjacent regions indicated that the value of arbor-shrub layer species Shannon-Wiener index was lower than that of Endospermum chinense community in Hong Kong, Cryptocarya chinensis community in Dinghushan Natural Reserve and Schefflera heptaphylla community in Nanshan District Shenzhen City, owing to its insularity, dominant populations and invasive species. This situation suggested that some necessary measures should be taken to restore the diversity in Litsea monopetala community.
