广州市“九五”攻关重大课题 (98-z- 0 4 4 - 0 1)
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.
