摘　　要：对福建漳浦前湖湾潮间带两个钻孔岩心和表层沉积物中的有孔虫进行分析研究,有孔虫出现在钻孔最上部厚约2.46-2.96m的砂层中.根据群落优势种生态和非种特征判断,该段各样品有孔虫沉积环境均为近岸浅水环境,尽管其间海面有过3次上下波动变化.根据地层关系判断,其当为现代的产物.Foraminifera from two cores and surficial sediments in tide zone were analyzed in this paper. Foraminifera were found in the strata which depth is about 2.46 -2.96m of the top of the core. According to the zoology of community predominance species and the characteristic of nonspecies, we conclude that the deposit environment of the strata which have Foraminifera are all occurred onshore in the shallow water environment, though there were 3 fluctuations of sea level. Judged on the stratum relation, all sediment was from the modern times.
