摘　　要：通过样方调查,结合文献资料,对安徽南漪湖水生维管植物进行区系分析。结果表明,南漪湖水生维管束植物有26科33属47种。植物区系分析显示,除世界分布属外,温带分布在湖区占优势地位,表明南漪湖地处亚热带,为热带向温带过渡地区。植物区系具有明显热带、亚热带与温带的性质,以温带性质为主。通过濒危植物分析,发现南漪湖单种属、寡种属、少种属植物在所属33种植物所占比例超过60%,水生维管植物共(47种)占安徽省水生维管植物(共151种,包括3亚种,6变种)的31.2%,多样性明显偏低。There are aquatic vascular plants of 47 species belonging to 33 families and 26 orders in Nanyihu Lake of Anhui according to quadrats survey and references.The analysis of plant flora showed that the temperate distribution predominates in this lake district besides cosmopolitan.This area is located in the subtropical zone and the flora there is mainly temperate in nature with some tropical and subtropical features.Monotypic genera,minor genera and oligotypic genera are totally thirty three species,accounting for sixty percent of the forty seven aquatic vascular plants there,which is only forty seven percent of the congeneric plants in Anhui,revealing itself low diversity.
