摘　　要：通过实地调查并参考相关文献,对安徽水生维管植物的多样性进行了研究。结果表明:安徽共有水生维管植物142种、3亚种、6变种,隶属于76属,41科;具有4种生活型,组成了18个主要的植物群丛,其中挺水植物所占比例最高(56.7%),漂浮植物比例最低(7.3%)。分析安徽水生维管植物受威胁的原因,主要是湿地生境的破坏与恶化及外来种入侵等,因此,在加快湿地保护与建设的同时,应保护和利用湿地及水生植物的多样性。Diversity of aquatic vascular plants in Anhui province was investigated based on the field survey and literatures. The results showed that there were 142 species, 6 varieties, and 3 subspecies belonging to 76 genera and 41 families. They could be divided into four life forms, of which the emergent plants shared the highest proportion （56.7%） and the floating plants shared the lowest （7.3%）. The aquatic vegetation could be classified into 18 major types of association. The threatened status of the aquatic vascular plants＇ diversity was described. Some suggestions of restoration and conservation for the diversity were put forward.
