中文摘要：

以植物群落调查样地资料为基础，对福建龙栖山和梅花山国家级自然保护区南方红豆杉群落物种多样性特征进行了研究，测定了群落植物生长型构成以及各层次植物物种的重要值，采用多种测度方法计算了群落各层次植物物种的丰富度指数、均匀度指数和多样性指数。结果表明：南方红豆杉群落总体上物种多样性高，种类组成复杂；龙栖山国家级自然保护区南方红豆杉—毛竹群落植物生长型在物种丰富度、多样性指数及均匀度等多样性指数上表现出灌木层〉草本层〉乔木层的规律；梅花山国家级自然保护区南方红豆杉群落物种多样性指数则表现出乔木层〉灌木层〉草本层的规律。

英文摘要：

The characteristics of the plant species diversity of Taxus chinensis var, mairei community were studied in Longxi Mountmn National Nature Reserve and Meihua Mountain National Nature Reserve in accordance with the sampling data. The plant growth form and the importance value of the community were determined, and the richness, evenness, and species diversity indexes of each layer of the community were calculated by several calculation methods, In general, T. chinensis var. mairei community with complicated species structure has high species diversity. The species richness, species diversity and evenness of T. chinensis var. mairei and Phyllostachys edulis community in I.ongxi Mountain National Nature Reserve are all in the order of shrub stratum 〉 herb stratum 〉 tree stratum, while the species diversity index of the T. chinensis var. mairei community in Meihua Mountain National Nature Reserve shows tree stratum 〉 shrub stratum 〉 herb stratum.
