澳门公园植物多样性调查研究

Investigation and Study of Plant Diversity of Macao Parks

应用物种丰富度指数(S)、多样性指数(Shannon-Wiener指数)、优势度指数(Simpson指数)和均匀度指数(E)对澳门9个公园植物群落进行了研究。结果表明:50个样地共记录乔木111种,灌木137种,草本165种。不同公园物种多样性基本表现为灌木层≈乔木层>草本层;物种均匀度总体上为乔木层>灌木层>草本层;建议澳门在构建较高物种多样性植物群落的同时应优先选择乡土植物。

The species richness index （S）, diversity index （Shannon-Wiener index）, dominance index （Simpson index） and evenness index （E） are used to study the plant communities of nine parks of Macao. The results show that there are 111 kinds of trees, 137 kinds of shrubs and 165 kinds of herbs in the 50 sample lands. The plant diversity of different parks is basically shown as shrub layer〉tree layer〉herb layer, while the species evenness is generally as tree layer 〉 shrub layer 〉 herb layer. It is proposed to give priority to native plants in building higher species diversity plant communities in Macao.
