摘　　要：对2009年在云南南捧河自然保护区综合考察所采集的3000余号标本的物种组成、分布区类型和区系特征等进行分析。结果表明:保护区有种子植物155科660属1546种;种子植物区系具有明显的热带性质,主要由热带亚洲成分、东亚成分以及中国特有成分融合而成,同时表现出热带植物区系向亚热带区系过渡的趋势。在植物区系划分上,属于古热带植物区印度—马来西亚亚区滇缅泰地区滇南、滇西南小区。与相邻的小黑山和南滚河相比,特有现象明显,即该区有东亚特有科3科,中国特有属6属,中国特有种451种。The species composition,areal types and floristic characteristics of Nanpeng River Nature Reserve,located in the southwest of Yunnan Province,were analysed according to more than 3000 seed plant specimens collected in a comprehensive survey in 2009.A total of 1 546 species of wild seed plants were recorded,belonging to 660 genera of 155 families.The flora of seed plants consists of tropical Asian elements,east Asian elements and Chinese endemic elements,indicating a transition trend from tropical flora to subtropical flora.The flora belongs to the Yunnan south-southwest area of YunnanMyanmar-Thailand zone,India-Malaysia subkingdom,Ancient tropical kingdom in floristic regionalization.Judging from the fact that 3 families are endemic to East Asia and 6 genera and 451 species to China,the phenomenon of endemic flora in Nanpeng River Nature Reserve is quite conspicuous compared with the adjacent regions such as Xiaohei Mountain and Nangun River.
