根据2014年8月靖海湾的调查数据，对该海域的浮游生物和底栖生物的物种组成及多样性进行了分析。共鉴定出浮游植物2门19种，硅藻门是主要类群，占总物种数的78．95％，主要优势种为中肋骨条藻（Skeletonema costatum）；平均细胞丰度6．63×104个／m3。浮游动物26种，节肢动物为主要优势类群，占总物种数的46．2％；主要优势种为刺尾歪水蚤（Tortanus spinicaudatus）和太平洋纺锤水蚤（Acatia pacifica），优势度分别达0．403和0．313；平均丰度为1056个／m3。底栖动物24种，分别属于多毛类、软体动物和节肢动物。多毛类为优势类群，占总物种数的50．00％，主要优势种属为沙蚕科（Nereidae），平均丰度为58个／m2，平均生物量340．95 g／m2。多样性分析显示，该海域生物群落结构稳定，环境质量良好。

Based on the investigational data of Jinghai Bay in August 2014 ,the diversity of plankton and macrobenthos was analyzed .A total of 19 taxa of phytoplankton belonging to 2 phyla were identified , Bacillariophyta was the main group ,representing 78 .95% of the total species .The dominant specie was Skeletonema costatum ;the average of cell abundance was 6 .63 × 104 cells/m3 .A total of 26 species of zooplankton were identified ,Arthropoda was the main group ,representing 46 .2% of the total spe‐cies .The dominant species were Tortanus spinicaudatus and Acatia pacif ica ,the dominance was 0 . 403 and 0 .313 respectively ,with an average of 1 056 ind ./m3 .A total of 24 species of macrobenthos were found ,including Polychaeta ,Mollusca and Arthropoda ;Polychaeta was the main group ,represen‐ting 50 .00% of the total species ,the dominant species were Nereidae ;the average abundance of mac‐robenthos was 58 ind ./m2 ,and the average biomass was 340 .95 g/m2 .The analytic results of diversity show that the community structure was stable and the environmental quality was well in this area .
