通过对黄、东海海域底质沉积物中的细粒级粘土矿物组合特征和全粒级碳酸盐含量分析、对比上覆水团和悬浮体资料,探讨研究区水团发育消长对底质沉积物分布的影响作用。结果表明研究区可以划分为长江冲淡水影响的长江型物质沉积区;黄海水影响的黄河型物质沉积区和黑潮水以及东海次表层水影响的残留型物质沉积区。而水团发育消长可直接影响下伏底质的分布特征。黄河型物质沉积区与残留型物质沉积区的分界相应于黄海冷水向东南扩展与黑潮次中层混合水向陆架爬升互为消长的长期综合平衡位置,而黄海冷水向东南的扩展范围代表着黄河物质在陆架向东南扩展沉积的最大范围.
Based on the analysis of fine-grained clay mineral assemblages and whole-grain carbonate contents in the sediments of the Yellow Sea and East China Sea, the data of overlying water masses and suspensions were compared to investigate the effects of water-flow growth and decline on sediment concentration The impact of distribution. The results show that the study area can be divided into the Yangtze River sediment area affected by the Yangtze River water, the Yellow River sediment area affected by the Yellow Sea water and the Kuroshio water and the sediment area affected by the sub-surface water in the East China Sea. The growth and development of water masses can directly affect the underlying sediment distribution characteristics. The boundary between the Yellow River sediment depositional area and the residual sediment depositional area corresponds to the long-term integrated equilibrium where the Yellow Sea cold water extends to the southeast and the Kuroshio sub-middle mixed water to the shelf rise each other, while the extended range of the Yellow Sea cold water to the southeast represents the Yellow River The largest extension of sediment to the southeast in the shelf.
