摘  要：
为了掌握福建省武平县蕨类植物资源的种类和数量,对该县进行调查并分析其区系特征,可为科学、合理地保护和利用蕨类植物资源提供理论依据,对生态文明建设也有重要意义。采用生态学调查技术手段,依照野生植物调查技术规程中的线路法,以蕨类植物区系的物种组成、科属分布区类型为指标,并与其他地区进行比较开展福建武平蕨类植物区系的研究。结果表明武平县共有蕨类植物38科、71属、160种,其中新纪录种有71种,有3种属于国家重点保护植物。优势科为水龙骨科、金星蕨科、鳞毛蕨科、凤尾蕨科;鳞毛蕨属、凤尾蕨属、铁角蕨属、卷柏属、凤丫蕨属、毛蕨属为优势属。科的分布区类型有8个,其中热带分布科比例55.26%;属的分布区类型有11个,超过50%属均为热带分布,说明该区系具有明显的热带亲缘特征。通过与其他地区的比较,发现在中亚热带地区随着纬度的升高,蕨类植物的热带成分减少,温带成分增加。

摘  要：
In order to master the species and quantity of pteridophytes resources in Wuping County, Fujian Province, the investigation and analysis may provide theoretical basis for scientific protection and utilization of pteridophytes resources reasonably, which had great significance for the construction of ecological civilization. By the means of ecological investigation technology, according to the line method in the technical specification of wild plant investigation, the species composition, family and genus distribution of the pteridophytes flora, and comparison with other areas were taken as analysis indicators, the pteridophyte flora was studied in Wuping, Fujian Province. There were 38 families, 71 genera and 160 species of pteridophytes in Wuping County. Among them, 71 species were new records, there were 3 species belonging to national keyprotected plant. The dominant families were Polypodiaceae, Thelypteridaceae, Dryopteridaceae, Pteridaceae, and the dominant genera were Dryopteris, Pteris, Asplenium, Selaginella, Coniogramme, Cyclosorus. There were 8 areal-types of family, the proportion of tropical families was 55.26%, and there were 11 areal-types of genus, more than half of the genera were tropical distribution, those showed that the tropicalgenetic characteristics of pteridophytes flora were obvious. Compared with other regions, it was found that with the increase of latitude, the tropical component of pteridophytes decreased and the temperate component increased.
