摘　　要：采用粒级——标准偏差的方法对漳浦前湖湾海岸剖面刻槽采样获得的沉积物及海滩钻孔等间距采样获得的沉积物进行分析,并与该沉积物的磁化率变化曲线相对照,提取了反映环境变化的敏感粒度组分并分析了其环境指示意义.The paper made an analysis of the marine geological cut samplings of the sediments from the continuous profile and the Drilling Holes on the beach of the bay of Qianhu in Zhangpu by using the method of Grain-size Distribution. Then the paper analyzed the relationship between the sensitive grain size of marine sediments and magnetic susceptibility of the sediments, and the grain size that can be used as a kind of index reflecting the environment evolutions has been comfined.
