根据汛期黄河口多船同步水文泥沙实测资料 ,对黄河口最大浑浊带特征及其时空演变进行研究 ,得出汛期黄河口最大浑浊带在整个潮周期始终存在 ,其含沙量和范围形态受潮相的控制 ,在落急和落平时最为发育。文中还探讨了黄河口最大浑浊带的形成机制 ,指出其形成主要受河流携带大量泥沙、泥沙异重流、河口密度环流及湍流的作用 According to the measured data of synchronized hydrological and sediment in the Yellow River Estuary during the flood season, the characteristics of the maximum turbidity zone in the Yellow River Estuary and its temporal and spatial evolution were studied. It was found that the maximum turbid zone in the Yellow River Estuary in the flood season always existed throughout the tidal cycle, Phase control, the most urgent and fall when the most developed. The paper also discusses the formation mechanism of the maximum turbidity zone in the Yellow River Estuary, and points out that its formation is mainly affected by the large amount of sediment, sediment heavy flow, estuarine circulation and turbulence
