摘要
近年来,湖南常德太阳山的旅游业得到了极大发展,太阳山蕨类植物生存也因此受到了极大的干扰和破坏。为了合理开发利用和保护太阳山地区蕨类植物资源,本研究对太阳山地区蕨类植物资源的种类、分布、生境及其利用价值进行了研究。结果表明,太阳山地区现有蕨类植物17科20属32种。其中优势科为鳞毛蕨科(Dryopteridaceae,3属9种),优势属为鳞毛蕨属(Dryopteris,6种)、凤尾蕨属(Pteris,4种)。该区蕨类植物生境多样化,以林下、林缘为主,共有17种,占总种数的53.1%。生态型以陆生为主,共有25种,占太阳山地区蕨类总种数的78.1%。太阳山药用蕨类植物资源丰富,共有23种,占总种数的71.9%。
Recently, tourism of Taiyangshan develops rapidly which brings great disturbance, interferenceand destruction to ferns in this area. In order to reasonable utilize and protect ferns resources, the fernplants in Taiyangshan were studied about their species, distribution, habitats and utilization values. Theresults showed that the existing fern plants included 17 families, 20 generas and 32 species. The dominantfamily is Dryopteridaceae which included 3 generas and 9 species. The dominant generas was Dryopterisincluded 6 species and Pteris included 4 species, respectively. The fern plants had great diversity in habi-tats. The vast majority of them, including 17 species which accounted for 53.1% of all species, likely livedunder forests and forest margins. The dominant ecological model was land, including 25 species which ac-counted for 78.1% of all species. Medicinal pteridophyta resources in Taiyangshan were rich which includ-ed 23 species and accounted for 71.9% of all species.
