摘　　要：对温州三垟湿地维管束植物进行调查和鉴定,研究其植物种类组成及其物种多样性特征,并与杭州西溪湿地、绍兴镜湖湿地作比较,评价其健康性。结果表明:1)温州三垟湿地共有259种野生维管束植物,隶属于187属73科;2)有湿地植物66种,包括沉水植物2种,漂浮植物3种,浮叶生根植物3种,挺水植物25种,湿生植物33种;3)有国家保护植物4种,建议列入保护的易危植物1种,同时有外来入侵植物28种;4)相比于杭州西溪湿地、绍兴镜湖湿地,温州三垟湿地物种丰富度不高,水生植物尤其是沉水植物所占比例偏低,国家保护植物种类少,外来入侵植物种类多,表明其健康性较差;5)从维管束植物体现出三垟湿地的湿地植物生长环境已受到破坏,尤其是水体污染严重,生态系统脆弱而极易受损,亟待保护和修复。The composition and diversity characters of the vascular plant species were investigated and identified in Sanyang wetland of Wenzhou, Zhejiang. The eeo-health of Sanyang wetland was assessed by comparing with Xixi wetland in Hangzhou and Jinghu wetland in Shaoxing, Zhejiang. Result showed that： 1） there were 259 kinds of vascular plants in Wenzhou Sanyang wetland, belonging to 187 genera and 73 families; 2） there were 66 wetland specialist species, including 2 submerged species, 3 fluitante species, 3 floating-leaves rooted species, 25 emerged species and 33 hygrophyte species; 3）there were 4 species included in state protected plant list, 1 species of suggesting to be protected and 28 exotic invasive plant species; 4）comparing with Xixi wetland and Jinghu wetland, the ratio of the aquatic species, especially submersed plants relative to total plant species, the species richness and the number of the state protected species of this wetland were low, while the number of the exotic invasive plant species were relatively high, which showed that the eco-health of Sanyang wetland was worst; 5） the results above indicated that the habitat for subsistence of wetland plant species in Sanyang wetland was destroyed by serious water pollution, and the ecological system was fragile, which needed to be protected and repaired.
