摘　　要：根据2012年~2013年在台山列岛周边海域进行的4个航次底拖网调查资料,并结合该海域的历史资料系统整理了台山列岛周边海域鱼类总名录,使用PRIMER 5.0软件计算了该海域鱼类的分类多样性指数,研究了分类多样性指数的季节变化。结果显示,台山列岛周边海域共记录鱼类2纲20目81科150属208种,以鲈形目种类占绝对优势;2012年~2013年调查记录到鱼类2纲11目40科63属77种。台山列岛周边海域鱼类的平均分类差异指数(△^+)和分类差异变异指数(∧^+)的理论平均值分别为63.14和378.4。鱼类分类多样性指数(△)秋季最高,春、夏季次之,冬季最低;鱼类分类差异指数(△~*)秋季最高,春季次之,夏、冬季较低。研究结果表明,春季鱼类种类数最多,夏、秋季次之,冬季最少,水温和饵料决定了研究海域鱼类种类组成。According to the data collected from four seasonal trawling surveys between 2012 and 2013 in the waters surrounding the Taishan Islands,we made a list of fish species in this area and calculated its taxonomic diversity by PRIMER 5. 0. We identified 208 fish species including 2 classes,20 orders,81 families and 150 genera in the waters around Taishan Islands,with Perciformes being the major order. According to the survey data from 2012 to 2013,77 fish species including 2 classes,11 orders,40 families and 63 genera were identified. The average taxonomic distinctness（ △~＋） and variation in taxonomic distinctness（ ∧~＋） of fish species listed in that area were 63. 14 and 378. 4,respectively. The taxonomic diversity（ △） and taxonomic distinctness（ △~＊） were higher in autumn and spring than in summer and winter. It is concluded that the species in spring was more than that in summer and autumn,and was the least in winter. Water temperature and food were the main factors which affect fish species composition.
