摘要
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：ＡｍｍｏｎｉａｂｅｃｃａｒｉＥｌｐｈｉｄｉｕｍｍａｇｅｌａｎｉｃｕｍ，ＡｍｍｏｎｉａｂｅｃｃａｒｉＥｌｐｈｉｄｉｕｍａｄｖｅｎｕｍ和ＡｍｍｏｎｉａｂｅｃａｒｉＴｅｘｔｕｌａｒｉａｆｏｌｉａｃｅａ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。
Result based on analysis of 52 surface sediment samples collected from Haizhou Bay shows that the foraminiferal taphocoenose of the studied area consists of over 100 species dominated by Ammonia beccarii, Elphidium magellanicum, Elphidium advenum and Textularia foliacea . Three faunal assemblages ( Ammonia beccarii-Elphidium magellanicum, Ammonia beccarii-Elphidium advenum and Ammonia beccarii-Textularia foliacea ) are identified according to the dominant species. Planktonic forms are absent in the bay area meanwhile some small test size planktonic forms are frequently encountered in the Guanhe River mouth area near the south end of the bay. The spatial distribution of foraminiferal abundance, diversity, faunal composition and assemblages are basically parallel to the coastline and the distribution of water depth, salinity and sediment grain size.
