摘　　要：对济州岛附近海域表层沉积物中的颗石进行研究,共发现40个种。根据对颗石进行多元统计分析的结果,可将本区划为两个环境区、两个颗石组合。提出海流是控制本区颗石分布的主要因素。The coccoliths in the surface sediments from Ji-Zhou Island Sea Region were recognized.Forty coccolithophore species were found.According to the results of mulryvariate analysis of the coccoliths in the sediments,two different environmental areas and coccoliths assemblages were established.The currents were thought to be the most important environmental factors controlling the distribution of the two coccoliths assemblages.
