５２个表层沉积样品的定量分析表明，海州湾有孔虫埋葬群由１００多种组成，其中４４种为常见种，优势种有Ａｍｍｏｎｉａｂｅｃａｒｉ，Ｅｌｐｈｉｄｉｕｍｍａｇｅｌａｎｉｃｕｍ，Ｅｌｐｈｉｄｕｍａｄｖｅｎｕｍ及Ｔｅｘｔｕｌａｒｉａｆｏｌｉａｃｅａ等，据之可划分出：ＡｍｍｏｎｉａｂｅｃｃａｒｉＥｌｐｈｉｄｉｕｍｍａｇｅｌａｎｉｃｕｍ，ＡｍｍｏｎｉａｂｅｃｃａｒｉＥｌｐｈｉｄｉｕｍａｄｖｅｎｕｍ和ＡｍｍｏｎｉａｂｅｃａｒｉＴｅｘｔｕｌａｒｉａｆｏｌｉａｃｅａ三大组合。浮游有孔虫仅在灌河口海域有少量分布。有孔虫丰度、分异度平面分布差别甚大，但与岸线大致呈平行之势分布，这与海州湾水深、盐度、海底沉积物粒度等特征平行岸线分布的规律基本一致。 Quantitative analysis of 52 surface sediment samples showed that the foraminiferal burial group in Haizhou Bay consisted of more than 100 species, of which 44 species were common species. The dominant species were Ammoniabecari, Elphidiummagelanicum, Elphidumadvenum and Textulariafoliacea, which could be divided into Ammoniabeccari  Elphidiummagelanicum, Ammoniabeccari  Elphidiumadvenum and Ammoniabecari  Textularia  foliacea three combinations. Planktonic foraminifera only distributed a small amount in the estuary waters. The distribution of foraminiferal abundance and degree of differentiation varies greatly, but is roughly parallel to the coastline. This is consistent with the regularity of the parallel shoreline distribution along Haizhou Bay, such as water depth, salinity and seabed sediment grain size.
