统计分析了安徽鹞落坪国家级自然保护区的维管植物区系,该区共有维管植物132科、471属、925种(含种下分类群)。科以泛热带分布最多,达38.89%,热带分布多于温带分布(59/29);属以北温带分布最多(26.87%),温带分布多于热带分布(266/134);种以中国特有分布最多(37.40%),温带分布多于热带分布(350/219)。将中国特有种划分成8个分布亚型,其中以华东-华中-西南分布最多(156种)。研究结果表明,鹞落坪保护区植物种类丰富,地理成分多样,温带成分优势明显,热带成分次之,并且拥有众多特有?珍稀濒危植物,区划上属于华东植物区系。

The flora of vascular plants in Yaoluoping nature reserve in Anhui province is analyzed. 925 species which belong to 471 genera in 132 families are recorded in this reserve totally. At family level, the proportion of the pantropic type is more than the others and reaches 38.89% , the tropic elements are more than temperate ones（59/29）. At genus level, the north temperate type is 26. 87% , the temperate elements are more than the tropic ones（266/134）. At species level, the endemic to China type reaches 37. 40% , and the temperate elements are more than the tropic ones（350/219）. The endemic to China can be divided into 8 subtypes, among which East China, Central China and South-west China takes the biggest proportion （ 156 species）. The vascular plants in Yaoluoping nature reserve are very rich and their geographical elements are complex. Flora is of more obvious temperate feature than tropic feature.
