依据表层沉积物碳酸盐及元素 Ca、Sr、Ba特征 ,探讨了南黄海表层沉积物的来源及其动力成因。现代黄河物质及老黄河三角洲物质以高钙、高碳酸盐和高 Ca/ Sr比值为特征 ;海区东北部物质以低钙、低碳酸盐、低 Ca/ Sr与 Sr/ Ba比值为特征 ,长江物质以碳酸盐及 Ca O含量、Ca/ Sr与 Sr/ Ba比值中等为特征。表层沉积物碳酸盐、Ca O含量及 Ca/ Sr、Sr/ Ba比值的分布对不同特征沉积物的搬运和沉积具有很好的指示意义 ,南黄海北部 Sr/ Ba低值带沿NE- SW向延伸大体反映了黄海暖流的入侵路线。
Based on the characteristics of carbonate and Ca, Sr and Ba in surface sediments, the origin of the surface sediments in the South Yellow Sea and its dynamical origin were discussed. The materials of the modern Yellow River and the Yellow River Delta are characterized by high calcium, high carbonate and high Ca / Sr. The northeastern part of the sea area is characterized by low calcium, low carbonate, low Ca / Sr and Sr / Ba, The Yangtze River is characterized by carbonate and CaO content, moderate Ca / Sr and Sr / Ba ratios. The distributions of carbonate, CaO and Ca / Sr and Sr / Ba in surface sediments are good indicators of the transport and sedimentation of different sediments. The northern part of southern Yellow Sea along the NE-SW The extension generally reflects the intrusion of the Yellow Sea warm current.
