海南岛药用蕨类植物多样性及生境分布类型

Diversity and Habitat of Pteridophyte Herbs in Hainan Island

海南岛药用蕨类植物资源丰富,约有100余种,其中多数是习见种类,以卷柏科Selaginel-lacea、水龙骨科Polypodiaceae、铁角蕨科Aspleniaceae等科的蕨类为主,药材蕴藏量大.另有一些药用蕨类未见于典籍,是本岛海南黎族同胞的独特用药.海南岛药用蕨类多数分布于热带季雨林及沟谷雨林之中,少数见于旱脊地带.海南岛药用蕨类植物资源缺乏深入系统的研究,很多有效的蕨类成分尚未得到认识和利用.本岛民间验方、偏方中的药用蕨类需要进行深入发掘和推广.

There are more than 100 species of pteridophyte herbs in Hainan Island.Most of them are locally common in Hainan, but some are rare and endangered species.Many of them are from these families, such as Selaginellacea, Polypodiaceae and Aspleniaceae.Some species have never been recorded as medicinal plants and are only used by Li people in Hainan.Most of pteridophyte herbs grow under tropical monsoon forest and ravine rainforest while few grow in dry and lean soil.The active ingredients of these pteridophyte herbs would be extracted and analyzed, and the Ethno pteridophyte herbs in Hainan, especially by the Li people should be studied.
