| 摘 要： | 本文通过对黄河三角洲埕岛海域146个表层样的粒度分析,表明该区有5种沉积物类型,以砂质粉砂为主体,呈斑块状分布,极细砂与粗粉砂是沉积物的主要粒级,普遍分选差。运用"粒径趋势"分析的方法,分析探讨了埕岛海域表层沉积物净输运趋势。研究区的沉积物的净输运趋势大致以12 m水深为界,深水区沉积物的净输运趋势向岸,12 m以浅海域的沉积物具有离岸的净输运趋势,说明深水区沉积物受冬季风浪作用向岸运移作用显著,12 m以浅海域的沉积物受夏季风浪作用离岸运移作用显著,沉积物运移的季节变化已成为研究区海域沉积物净运移的主要控制因素。

| Abstract: | Using the data of grain size analysis of 146 sediment samples in the Chengdao sea area and grain size trend analysis method,the surface sediments characteristics and the net transport patterns in this area were been studied.Results showed that the Chengdao sediments could be divided into five categories as sandy silt,silt,silty sand,sandy mud and mud,which mainly covered by sandy silt and distributed in patch.The sediments in study area that the chief aggregate classes were very fine sand and coarse silt we... |
