摘要:

为了解白云山与越秀山蕨类植物组成与区系特点,通过实地考察和文献分析对其进行研究。结果表明:两地共有蕨类植物77种,隶属于22科41属,科的相似度为81.82%,属的相似度为58.54%,种的相似度为49.35%。白云山和越秀山优势科(种数≥5)均为凤尾蕨科和金星蕨科。两地蕨类植物科和属区系均以泛热带分布和世界分布为主,其中,泛热带分布共有11科,占比52.38%,世界分布6科,占比28.57%;泛热带分布共有18属,占比50.00%,世界分布9属,占比25.00%;种的区系以泛热带分布和热带亚洲分布为主,泛热带分布38种,占比57.58%,热带亚洲分布15种,占比22.73%。因此,该地区具有显著的热带亚热带植物区系属性。

Abstract:

In order to understand the composition and floristic characteristics of Pteridophytes in Baiyun Mountain and Yuexiu Mountain, the field investigation and literature analysis were carried out. The results showed that there were 77 species of Pteridophytes in the two places, belonging to 22 families and 41 genera. The similarities of families, genera and species were 81.82%, 58.54% and 49.35%, respectively. The dominant families (species≥5) in Baiyun Mountain and Yuexiu Mountain are Pteridaceae and Thelypteridaceae. The flora of families and genera of Pteridophytes in the two places are dominated by pantropic distribution and world distribution. Among them, there are 11 families in pantropic distribution, accounting for 52.38%, and 6 families in the world distribution, accounting for 28.57%; There are 18 genera in pantropical distribution, accounting for 50.00%, and 9 genera in the world distribution, accounting for 25.00%; The flora of species is dominated by pantropical distribution and tropical Asia distribution, 38 species are distributed in pantropical distribution, accounting for 57.58%, and 15 species are distributed in tropical Asia distribution, accounting for 22.73%. Therefore, the region has a significant tropical and subtropical flora attribute.
