摘　　要：根据2016年4月(春季)、7月(夏季)、10月(秋季)和2017年1月(冬季)瓯江干流温州段的渔业资源调查资料,对瓯江干流温州段鱼类的种类组成、资源状况、重要种类的生态优势度、多样性指数等动态变化进行了分析。结果表明:瓯江干流温州段现有鱼类33种,隶属于8目、15科、26属;四季全部调查水域中出现的优势鱼种有中国花鲈、凤鲚和短吻红舌鳎等3种,其中中国花鲈常年优势种。Margalef丰富度指数(D)介于0.59~0.94,Shannon-Wiener多样性指数(H′)介于1.76~2.11,Pielou均匀度指数(J′)介于0.68~0.87,依此判定瓯江干流温州段鱼类群落的多样性属于正常水平。According to the data of fishery resources in the Wenzhou section of Oujiang River mainstream in spring（Apr 2016）, summer（Jul 2016）, autumn（Oct 2016） and winter（Jan 2017）, the dynamic changes of fish communities, fish resources, the ecological dominance of important species, and the biodiversity index were analyzed. The results showed that there were 33 fish species belonging to 8 orders, 15 families and 26 genera in the Wenzhou section of Oujiang River mainstream. The yearly dominant species were Lateolabrax maculatus（Bloch）, Coilia mystus（Linnaeus） and Cynoglossus joyneri Günther, in which L. maculatus was the perennial dominant species in the four seasons. Margalef richness index（D） ranged from 0.59 to 0.94, ShannonWiener diversity index（H＇） ranged from 1.76 to 2.11, and Pielou evenness index（J＇） ranged from 0.68 to 0.87.The biodiversity of fish communities in the Wenzhou section of Oujiang River mainstream is normal.
