摘要
江西银凤岭省级森林公园位于萍乡市芦溪县境内,植物种类丰富,区系地理成分复杂.通过野外调查和查阅文献,对森林公园种子植物的科、属类型进行统计分析.结果表明,江西银凤岭省级森林公园共有种子植物499种,隶属于123科346属,分布有国家级重点保护野生植物苏铁(Cycas revoluta)、银杏(Ginkgo biloba)、水杉(Metasequoia glyptostroboides)等7种.其中,菊科(Asteraceae)、蔷薇科(Rosaceae)、蝶形花科(Papilionaceae)等为优势科,含笑属(Michelia)、蓼属(Polygonum)、李属(Prunus)等为优势属,杉木(Cunninghamia lanceolata)、马尾松(Pinus massoniana)、湿地松(P.elliottii)等是森林公园优势物种.科的分布区系类型以热带分布为主,占总科数的43.8%;其次是温带分布,占总科数的23.6%.属的分布区系类型主要为温带分布和热带分布,二者分别占总属数的46.3%和43.6%.
Abstract
Yinfengling Provincial Forest Park is located in Luxi County.The Forest park possesses a variety of species and complex geographical floristic elements.Based on field studies and relevant scientific literatures,this study counted and analyzed the families and genera in Yinfengling Provincial Forest Park.The results showed:499 species of seed plants,distributed in 346 genera of 123 families were found in Yinfengling.Yinfengling contains 7 national key protected wild plants,such as Cycas revoluta,Ginkgo biloba and Metasequoia glyptostroboides,etc.The dominant families were Asteraceae,Rosaceae,Papilionaceae,etc.The dominant genera were Michelia,Polygonum,Prunus,etc.The dominant species were Cunninghamia lanceolata,Pinus massoniana and P.elliottii,etc.The families of tropical and temperate distribution patterns made up 43.8%and 23.6%of the total family number,respectively.Tropical distribution was in the dominant position.While at genus level,the temperate and tropical distribution patterns made up 46.3%and 43.6%,respectively.
