本文根据1995年的调查，报道了九龙江口外浯屿海域底栖生物的种类组成与数量分布。结果表明，本区底栖生物种类较丰富（116种），组成以多毛类（55种）、甲壳动物（36种）、软体动物（10种）和棘皮动物（9种）为主。底栖生物数量较大，平均栖息密度为300个／m2，平均生物量为31．03g／m2，数量分布较不均匀。底栖生物的分布与沉积物的关系较密切。
Based on the 1995 survey, this paper reports the species composition and quantitative distribution of benthic organisms in the outer Huangyu Island of Jiulongjiang Estuary. The results showed that the benthic species in this area are rich (116 species), mainly composed of polychaetes (55 species), crustacean (36 species), molluscs (10 species) and echinoderms (9 species). The number of benthic organisms was larger, the average habitat density was 300 / m2, the average biomass was 31.03g / m2, the number distribution was not uniform. The distribution of benthic organisms is closely related to the sediments.
