福建长汀汀江国家湿地公园维管植物的组成和地理成分

Composition and Geographical Elements of Vascular Plants in Fujian Changting Tingjiang National Wetland Park

2022年6月至11月期间,在福建长汀汀江国家湿地公园中,采用调查样线方法和重点普查方法,开展了维管植物野外调查,建立了维管植物名录,分析了维管植物的组成和地理成分。研究结果表明,调查期间,在该湿地公园中记录了114科299属424种维管植物,其中,有蕨类植物15科24属32种,有裸子植物5科5属5种,有被子植物94科270属387种;禾本科(Poaceae)、菊科(Asteraceae)、莎草科(Cyperaceae)和豆科(Fabaceae)为优势科,分别包含34属48种、22属33种、11属22种和15属20种维管植物,优势属不明显;维管植物的科和属的区系都既有明显的热带属性,又有一些温带成分;维管植物的区系丰富程度和种系分化程度都较低,维管植物的生存环境相对简单。

From June to November 2022,using survey sample line and key investigation methods,the field surveys for vascular plants were conducted in Fujian Changting Tingjiang National Wetland Park.A list of vascular plants was established,and the composition and geographical elements of vascular plants were analyzed.The research results showed that,during the survey period,114 families,299 genera,and 424 species of vascular plants had been recorded in the wetland park.Among them,there were 15 families,24 genera,and 32 species of pteridophytes,5 families,5 genera and 5 species of gymnosperms,94 families,270 genera,and 387 species of angiosperms.Poaceae,Asteraceae,Cyperaceae,and Fabaceae were dominant families,including 34 genera and 48 species,22 genera and 33 species,11 genera and 22 species,15 genera and 20 species of vascular plants,respectively.Dominant genus was not obvious.The families and genera of vascular plants had both obvious tropical attributes and some temperate components.The phylogenetic richness and species differentiation of vascular plants were low,and the living environment of vascular plants was relatively simple.
