为给不同取样地点或时期鱼类群落多样性的比较提供基础资料 ,根据 2 0世纪 80年代以来的黄、渤海底拖网调查 ,并综合迄今为止的鱼类分类学研究 ,系统地更新了黄、渤海鱼类组成名录 ,并计算了其等级多样性特征。结果表明 ,黄、渤海有鱼类 3 79种 ,隶属于 2 64属 ,12 9科 ,3 6目 ,3纲。其中软骨鱼类 12目 ,2 4科 ,5 0种 ;硬骨鱼类 2 3目 ,10 4科 ,3 2 8种。根据黄、渤海鱼类总名录 ,计算了其等级多样性指数 (Δ+ )和分类差异变异指数 (Λ+ )的理论平均值及 95 %置信漏斗曲线 ,其中等级多样性指数 (Δ+ )的理论平均值为 77.7。
In order to provide the basic information for the comparison of the diversity of fish communities at different sampling sites or periods, according to the Yellow River and Bohai Sea trawl surveys since the 1980s, and based on the taxonomic studies so far, systematically updated the yellow, Bohai Sea fish composition list, and calculate the level of diversity characteristics. The results showed that there were 3 79 species of fish in Yellow Sea and Bohai Sea, belonging to 264 genera, 129 families, 36 males and 3 classes. Including cartilaginous fish 12 heads, 24 families, 50 species; teleost fish 23 heads, 104 families, 328 kinds. The theoretical average and 95% confidence funnel curves of level diversity index (Δ +) and classification differential variation index (Λ +) were calculated according to the total catalogs of fish in Yellow Sea and Bohai Sea. The level diversity index (Δ +) The theoretical average is 77.7.
