摘要
对取自渤海中、南部海底表层的44个沉积物样品进行了硅藻分析。样品中共含硅藻20属41种,主要是潮间带、沿岸性底栖或浮游种类,其中尤以具槽直链藻Melosira sulc-ata和小环藻Cyclotella最多见。对本区的表层沉积硅藻用多元统计方法进行分区,共划分出三区、两亚区,井与其他海区进行了比较。
A total of 44 samples collected from the central and southern part of the Bohai Sea were analysed.In diatom assemblage,41 species belonging to 20 genera have been found.Most of them belong to intertidal and littoral species.According to the results of multivariate analysis of the diatoms in the surface sediments,three biogeographic areas could he identified in the investigated area
