基于样地调查和群落学分析基础上，分析了宝华山落叶阔叶林下蕨类植物的物种组成、总优势度、α多样性、β多样性指数及相似性系数，并对其叶质、叶型进行了讨论。结果表明：宝华山落叶阔叶林下蕨类植物共计12科18属25种，该森林系统中蕨类植物多样性虽然不高，但优势种群明显，优势种为黑足鳞毛蕨、阔鳞鳞毛蕨、贯众海金沙等。调查群落内纸质叶的蕨类，一回羽状和二回羽状叶占据优势地位，反映出该群落具有一定的旱生性。系统样地间β多样性指数与相似性指数及共有种成反比关系，与多样性研究的一般规律一致。

On the basis of sample investigation and community studies, the species composition, SDR,α-diversity andβ-diversity jac-card indexes and similarity index were studied. The results showed that 25 species were found, belonging to 12 families and 18 gen-era. The dominant species were conspicuous although species diversity of pteridophytes was relatively low in the forest, dominated by Dryopterisfuscipesr, Dryopterischampionii, Cyrtomiumfortuneiand Lygodiumjaponicum. These pteridophytes were dominated by simple and bipinnate pinnately compound leaf with papery leaves, which showed that the community was of xerophytism. The in-dex of β-diversity among different pteridophytes communities was inversely proportional to similarity index and common species, which was consistent with the general rules of diversity.
