澳门松山市政公园物种多样性特征

Species diversity of Guia Hill Municipal Park in Macao

根据实际情况,将澳门松山市政公园植物群落分为阴香群落、假萍婆群落、假萍婆+石栗群落,调查并分析了各群落的物种多样性特征。结果表明,乔木层、灌木层和草本层的物种多样性水平表现为灌木层较高,草本层与乔木层较低。但总体而言,这些群落的植物种类都较少,物种多样性水平尤其乔木层物种多样性水平低。因此,应加强抚育,可通过生态恢复改善环境条件,为生物多样性的发展创造条件;通过林分改造促进群落物种多样性水平的提高,同时也能丰富森林景观。

Based on field survey, the ecosystem of Guia Hill Municipal Park was classified into three communities, i.e., Cinnamomum burmanni community, Sterculia lanceolata community and Sterculia lanceolata ＋ Aleurites moluccana community, and species diversities of plant communities were measured for ecological construction of the park. Among three layers （tree, shrub and herb layer）, shrub layer showed the highest species diversity, following by tree and herb layer. However, in comparison with zonal climax, these communities had fewer species and lower species diversity, especially in tree layer. Some effective methods, such as ecological restoration and stand improvement, should be used to increase species diversity of communities and improve the forest landscape.
