摘要： 2004～2006年采用各种网具对长江河口区进行鱼类调查，查阅了当前所有在该水域进行的鱼类调查资料，系统整理了长江河口区鱼类总名录，并计算了其分类多样性.结果表明，长江河口区鱼类共有305种，隶属2纲28目101科215属.其中，软骨鱼纲共5目12科14属22种；硬骨鱼纲共23目89科201属283种.依据总名录计算出其平均分类差异指数Δ+（79.9）和分类差异变异指数Λ+的理论平均值及95%置信漏斗曲线，Δ+值比黄海、渤海和东海鱼类均稍高.

Abstract: Based on the fish surveys using various sample nets in the Yangtze River Estuary, combined with previous studies, the fish master list in this area was updated and its hierarchical diversity was analyzed. The results show that there are 305 species of fishes, belong to 2 classes, 28 orders, 101 families and 215 genera, recorded in the Yangtze River Estuary. The cartilaginous fishes are composed of 5 orders, 12 families, 14 genera and 22 species, while bony fishes composed of 23 orders, 89 families, 201 genera and 283 species. The funnel plots with 95% confidence limits for both average taxonomic distinctness (Δ+) and variation in taxonomic distinctness (Λ+) of the Yangtze River Estuary fish master list were established. The value of Δ+ is 79.9, a little higher than those in Yellow Sea, Bohai Sea and East China Sea.

Key words: taxonomic diversity, fish master list, the Yangtze River Estuary, taxonomic diversity, fish master list
