中文摘要：
通过对海底表层沉积物的粒度分析，探讨了山东半岛东北部滨浅海底质沉积物的类型和分布特征。结果表明，该区的底质类型主要为粘土质粉砂、砂质粉砂和粉砂质砂三种类型，其中粘土质粉砂约占该区沉积物分布面积的60％以上，呈侧倒的“Y”字形由西北向东南展布，沉积物各粒级组的含量与海流的方向和强弱有明显的相关性。
英文摘要：
In this study, grain size analysis surface sediment was carried out to reveal the distribution of surface sediment types and the characteristics of grain size of surface sediments in the littoral zone in the northeast part of the Shandong Peninsula. The results indicate that there are three main sediment types in the study sea area. They are as follows： claysilt, sandy silt and silty sand. Among them, the sediments of clay silt cover more than 60% of the study area, spreading from northwest to southeast like a reclining letter ＂Y＂. The particle content of different size-groups is strongly correlated with the direction and intensity of the ocean current.
