| 摘 要： | 根据黄河下游干流高村以下河道50个断面底质样,尾闾清8断面到口门附近的104个表层沉积物样品,以及2000年7—9月黄河三角洲滨海区18个断面123个表层沉积物的粒度分析结果,结合动力条件和水深资料,探讨沉积物性质和粒度特征的分布和变化规律。结果表明,高村以下河道河床沉积物呈现由粗到细的变化趋势;黄河三角洲滨海区的沉积物分布显示出"侵蚀区砂多、堆积区泥多,近岸砂多、岸外泥多"的分布变化规律。进一步分析可知,20 m水深为黄河入海泥沙分选粗化的界线。

| Abstract: | To study the peoperties and grain-size distribution characteristics of the bottom sediments from the downstream of the Yellow River to the delta nearshore area,bottom samples taken at 50 sections in the main stream of the downstream of the Yellow River below Gaocun,104 samples collected from section Q8 to the entrance and 123 samples taken at 18 sections in the delta nearshore area from July to September 2000 were analyzed and the hydrodynamic conditions and water depth data were also considered.It has been... |
