摘　　要：通过野外调查和文献查阅,对珠海淇澳岛石松类和蕨类植物进行统计,发现淇澳岛石松类和蕨类植物共有34科58属90种,科、属、种数分别占广东省石松类和蕨类植物总数的60.7%、41.7%、19.4%;优势科主要有水龙骨科Polypodiaceae、凤尾蕨科Pteridaceae、金星蕨科Thelypteridaceae、石松科Lycopodiaceae和卷柏科Selaginellaceae等;优势属有凤尾蕨属Pteris、石松属Lycopodium、卷柏属Selaginella和铁角蕨属Asplenium等。珍稀濒危保护野生石松类和蕨类植物有金毛狗Cibotium barometz、黑桫椤Alsophila podophylla和水蕨Ceratopteris thalictroides,均为国家二级保护植物。地理成分分析发现科、属、种的地理成分以热带成分占绝对优势,这与淇澳岛地处亚热带的地理位置相吻合。资源利用分析发现淇澳岛石松类和蕨类植物中具有较高利用价值的种类达43种,利用方式以药用和园林绿化与观赏为主。According to field investigation and literature review,the floristic composition and element of lycophytes and ferns were analyzed in Zhuhai Qi’ao Island,Guangdong province.The result showed that there were 90 species belonging to 58 genera and 34 families.The number of species,genus and family accounted for 19.4%,41.7% and 60.7% of the total in Guangdong province respectively.The dominant families were Polypodiaceae,Pteridaceae,Thelypteridaceae,Lycopodiaceae,Selaginellaceae,and so on.While the dominant genera were Pteris,Lycopodium,Selaginella,Asplenium,and so on.Three rare,endangered and protected wild lycophytes and ferns species were recorded in this region,e.g.Cibotium barometz,Alsophila podophylla and Ceratopteris thalictroides,all of which were second-class national protected plants.Geographical composition analysis of families,genera and species indicated that the tropical components were dominated,which accordance to the subtropical geographical location of Qi’ao Island.Utilization analysis on fern plant resource indicated that 43 species had high utilization value.And the main resource utilization values of Qi’ao Island ferns were medicinal and ornamental value.
