| 摘 要： | 依据2010年在登州浅滩海域采集的沉积物样品资料,划分了研究区表层沉积物的分布类型,分析了登州浅滩海域沉积物的分布特征和粒度参数变化规律,在此基础上初步探讨了沉积物分布的影响因素。研究结果表明,登州浅滩海域表层沉积物主要包括砾石、砾砂、粗砂、中粗砂、中砂、细砂、粉砂质砂、砂质粉砂、粉砂、黏土质粉砂、粉砂质黏土等11种类型;浅滩沉积物以中粗砂为主,水道东侧以砾砂为主,西侧主要成分为黏土质粉砂;沉积物粒径具有自南向北由细变粗再变细,自东向西由粗变细的趋势;区域表层沉积物的分布格局与水动力环境相适应。 |

| Abstract: | Based on the samples taken in September and October 2010,we studied the types of sediments and their distribution pattern in the Dengzhou Shoal area.Grain size parameters are presented and the major factors controlling the sediments distribution discussed in this paper.The sediments of the area can be divided into 11 types,namely gravel,gravel sand,coarse sand,medium coarse sand,medium sand,fine sand,sandy silt,silty sand,silt,clayey silt,and silty clay,with medium to coarse sand as the major.Gravel sands a... |
