本文对2011年内采自我国长江口以北渤海和黄海近岸海域11个站位67个表层沉积物样品进行硅藻鉴定分析,共鉴定出硅藻118个种和变种,隶属于30个属。主要以近岸广布种为主,海水种和半咸水种占绝大多数。硅藻平均丰度为7198粒/g,其中渤海为4674粒/g、黄海北部为22427粒/g、黄海西部为6342粒/g,总体明显低于长江口以南近岸海域。根据硅藻优势种和次优势种的分布特征,在长江口以北近岸海域共划分出6个硅藻组合和2个亚组合。

There are 118 species and varieties,belong to 30 diatom genera,were identified in 67 coastal surface sediment samples from 1 1 stations in the north of China Seas (Bohai Sea and Huanghai Sea). They were constituted mainly by coastal widespread species,sea water species and brackish water spe-cies.The average abundance of diatoms was 7198 particle/g (4674 particle/g in Bohai Sea,22427 parti-cle/g in the northern Yellow Sea,and 6342 particle/g in western Yellow Sea),which were obviously lower than the southeast of China coast.According to the distribution pattern of dominant and sub-dominant species,six assemblages and two sub-assemblages of diatoms were divided in the north of China.
