摘　　要：通过整理1983～1986年采集的渤海鱼类复殖吸虫标本,共发现复殖吸虫14科48属84种,主要分布在内海的塘沽、秦皇岛、黄骅等地。复殖吸虫多样性分布特征呈现由内海到外海逐渐递减的变化趋势。这种变化趋势受物种数、优势种的聚集强度、鱼类多样性、水环境等因素的影响。Digenetic trematodes diversity was analyzed based on the investigation of digenetic trematodes of fish carried out in the Bohai Sea from 1983 to 1986.Total of 84 species belonging to 48 genus and 14 families were identified,mainly distributed in inside sea,such as Tanggu,Qinhuangdao,Huanghua,ect.The characteristic of distribution on diversity of digenetic trematodes of fish was the species diversity indices（H′） inside sea higher than outside sea.Several reasons were proposed to explain this distribution,including the number of species,the aggregation of the dominant species,the diversity of fish,the aquatic envionment,and so on.
