摘要/Abstract

摘要：为寻找更多、更有效的砷富集蕨类植物，对湖南省石门县雄黄矿场砷富集区的蕨类植物的种类及其生长状况进行了系统性调查分析.蕨类植物的亲缘关系分析结果表明：湖南省石门县雄黄矿场砷富集区的22种蕨类植物中有5种蕨类植物属于凤尾蕨类，5种属于金星蕨-铁角蕨类，4种属于鳞毛蕨类，其余7种则分散于蕨类植物的其他类群.频度及多度分析表明：蜈蚣草（Pteris vittata）、井兰边草（P.multifida）、渐尖毛蕨（Cyclosorus acuminatus）和贯众（Cyrtomium fortunei）在高砷地区有较高的频度和多度.石门高砷区生长的蕨类植物和已报道的砷富集蕨类植物的系统发育关系及其生物习性表明凤尾蕨类植物中发现了新的砷富集者.

Abstract: Base on our recent study,22 species of ferns and their companion plants in an arsenic-rich area in Hunan are reported in this paper.And the analyses on the systematic relationship,frequence and abundance,and the adaptability of these ferns are given in order to find more arsenic-accumulating ferns.The result shows that there is a little more species in Pteridoid series,Thelypteridoid-Asplenioid series and Dryopterioid series than that in the other groups.The species with higher abundance and higher frequence in the arsenic-rich area are Pteris vittata,P.multifida,Cyclosorus acuminatus and Cyrtomium fortunei.The growth relationship and the biohabits of the ferns in the arsenic-rich areas of in Shimen and other reported arsenic-accumulating ferns show that there are new arsenic accumulation in Pteridoid series.

Key words: arsenic-accumulating ferns, phylogenetics, vegetation restoration
