| 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。 |

| Abstract: |
| 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 werePolypodiaceae, 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. |
