摘　　要：有效保护珍稀濒危植物是建立自然保护区的主要目的之一。野外调查结果表明:(1)赣江源自然保护区共有珍稀濒危植物124种,隶属48科82属,其中国家重点保护植物有19种(含栽培),IUCN物种红色名录收录的有21种,中国物种红色名录(CSRL)收录的有52种,CITES名录附录Ⅱ收录的有29种,江西省重点保护野生植物名录收录的有98种;(2)赣江源自然保护区珍稀濒危植物(不包括蕨类植物和栽培植物)所含的属分布类型有13个,热带性分布属(37属)与温带性分布属(36属)数量基本相等,表明该植物区系属于温带-亚热带过渡类型;中国特有分布属5属,特有现象不明显;孑遗植物丰富,区系起源古老。One of the main purposes of establishing nature reserves is providing effective protection for rare and endangered plants.Field survey results show that:First,there are 124 species of rare and endangered plants which belong to 82 genera and 48 families in Ganjiangyuan Nature Reserve,Jiangxi Province,including 19 species of national key protected plants(Including cultivation),21 species in the International Union for Conservation of Nature(IUCN)Red List,52 species in China Species Red List(CSRL),29 species in the Convention on International Trade in Endangered Species(CITES),98 species in List of key protected wild plants in Jiangxi Province.Second,there are 13 types of genus in rare and endangered plants(excluding ferns and cultivated plants)in Ganjiangyuan Nature Reserve.The number of tropical genera(37 genera)and temperate genera(36 genera)is basically the same,indicating that the flora belongs to the temperate and subtropical transition type.The endemic distribution is 5 genera in China,and the endemic phenomenon is not obvious.Relict plants are abundant and floristic origin is ancient.
