南黄海夏季表层海水中悬浮体的高值区出现在苏北近岸一带,测得的最高值为7.57mg/L,其次是长江口和调查区的北部.低值区大面积分布在调查区的中部和山东半岛以南,悬浮体含量小于0.5mg/L.远岸的悬浮体垂向分布中有一个极为明显的分层性.在长江口外的悬浮体分布中可看到台湾暖流的影响,它的存在限制了长江入海物质的向东扩散.尽管7月是黄河和长江的丰水期,大量物质被携带入海,但还未能构成悬浮体的主要来源.其主要来源是沉积物的再悬浮,其次才是河流携入的物质,海水中的生物组分居三.现代河流入海物质的影响范围主要是调查区南北两端.在深水区,温度、盐度跃层的形成限制了底层悬浮体向上扩散.海水中物质的运移主要在海水底层进行,以悬浮—沉积—再悬浮—再沉积的方式进行着物质的运移和交换.
The high value area of the suspended sediment in the surface seawater of the South Yellow Sea in summer was found near the north coast of Jiangsu Province, with the highest value of 7.57mg / L, followed by the Changjiang Estuary and the northern part of the survey area. And the south of Shandong Peninsula, the content of suspended solids is less than 0.5mg / L. There is a very obvious stratification in the vertical distribution of the suspended sediment in the far bank.The influence of the warm current in Taiwan can be seen in the distribution of the suspended solids in the Yangtze River estuary , Its existence limited the eastward expansion of the material entering the sea from the Yangtze River.Although a large amount of material was carried into the sea in July during the flood season of the Yellow River and the Yangtze River, it did not constitute the main source of the suspended matter, and its main source was sediment Resuspension, followed by the river to carry the material, the biological components of the sea three. The impact of the modern river into the sea material is mainly north and south of the investigation area in the deep water, temperature, salinity thermocline formation limits the bottom The upward diffusion of the suspended matter.Material transport in the seawater is mainly carried out in the bottom of the seawater, the material migration and exchange in the form of suspension-sedimentation-resuspension-redeposition.
