| 摘 要： | 通过对龙口港航道附近小范围内表层沉积物的粒度分析，探讨该港口航道附近的表层沉积物的类型和分布特征。结果表明：1）研究海域的表层沉积物类型分为砂、粉砂质砂、砂质粉砂和粘土质粉砂4种。2）研究海域的表层沉积物主体是砂，其主要变化趋势是由岸到海砂的质量分数逐渐减小又逐渐增大。从它们平面分布来看，粉砂粒组与砂粒组含量的平面分布特征正好相反，粘土含量的平面分布特征与粉砂相似。3）研究海域表层沉积物的平均粒径为2．14～12．79Φ，平均为7．7Φ，沉积物颗粒的直径总体上为细砂粒径；分选系数为0．55～2．99，平均为1．82，分选差；偏态为一0．10～O．75，平均为o．20；峰态为0．63～2．76，平均为1．01。

| Abstract: | Grain-sizw Analysis of the surface sediments from the water area closely adjacent to the navigating channel to Longkou Harbour is carried out to discuss the sedimental types and their distributions in the studied area.As the results show,1) There are 4 types of sediments in the area,including sand,silty sand,sandy silt,and clayey silt.2) The main sedimental type is sand,which holds the dereasing percentage of the sediments from the nearshore to the offshore area,and the inereasing percentage to the further ... |
