    摘要:

    对白云山天然常绿阔叶林群落植物区系进行了分析,样地调查结果表明,该群落种类丰富,维管束植物共有53科85属103种。该区系的主要表征科为樟科,茜草科,芸香科,大戟科,桑科,冬青科,壳斗科等,它们绝大多数科是热带亚热带科,从属的地理分布区类型来看,以泛热带分布属的比例最高,其次依次为热带亚热带亚洲分布属,旧世界热带分布属,但缺乏典型的热带成分。白云山天然常绿阔叶林群落的区系成分和区系的标志种均较好地反映了本地带区系成分组合特征,这对于白云山风景区的林分改造方向是建立近自然的人工群落具有重要的参考价值。

    Abstract:

    Floristic composition of the evergreen broadleaved forest in Baiyunshan, Guangzhou, was analyzed based on community survey data. Field survey indicated that the community was rich in species diversity, with 53 families of vascular plants including 85 genera and 103 species. Dominant families of the flora were Lauraceae?Rubiaceae?Rutaceae? Euphorbiaceae? Moraceae?Aquifoliaceae and Fagaceae, most of which are tropical and subtropical. As for generic distribution, the Pan tropic areal type has the majority of genera, followed by Tropical Asia and Old World Tropics, while typical tropical genera are rare. Floristic composition of the evergreen forest community in Baiyunshan and the characteristic species of the flora epitomizes the zonal flora, which will provide scientific foundation for stand rehabilitation and stand establishment approximating to the natural forest community. This study also indicates that the sampled data based on community research are valid and convenient for floristic analysis.
