渤、黄、东海是一个水动力状况相当复杂的半封闭宽陆架海,本海区悬浮颗粒物含量高,季节变化明显,影响范围广,是世界上悬浮物含量最高的海域之一。对于该海域悬浮物的输运沉积过程、分布规律以及底质分布等中外学者均进行过比较深入的研究(秦蕴珊,1963;Honjo et al.,1974;Milliman et al.,1985,1986;秦蕴珊等,1987,1989;杨作升等,1992;Li et al.,1997;孙效功等,2000;雷坤等,2001)。然而,以往的研究大都基于实际海洋调查资料,由于受实测资料在时间和空间覆盖范围上的限制,很难从整体上把握渤、黄、东海陆架区悬浮物输运的时间和空间变化规律。数值模拟的方法能很好地克服上述局限,已有学者从不同角度对渤、黄、东海的某些海域的悬浮物进行了模拟研究。
The Bohai Sea, the Yellow Sea and the East China Sea are a kind of semi-enclosed, wide shelf sea where the hydrodynamic conditions are rather complicated. The content of suspended particles in this sea area is high, the season changes obviously, and the influence scope is wide. It is one of the highest suspended matter in the world. Chinese and foreign scholars such as sedimentation process, distribution law and distribution of sediment in this area have carried out comparative studies (Qin et al., 1963; Honjo et al., 1974; Milliman et al., 1985 and 1986; Qin Yun-shan et al. , 1987, 1989; Yang Zusheng et al., 1992; Li et al., 1997; Sun et al., 2000; Lei Kun et al., 2001). However, most of the previous studies are based on actual oceanographic data. Due to the limited time and space coverage of measured data, it is difficult to grasp the temporal and spatial variation of suspended matter transport in the Bohai Sea, Yellow Sea and East China Sea Shelf areas as a whole. The numerical simulation method can well overcome the above limitations. Some scholars have studied the suspended matter in some sea areas of Bohai Sea, Yellow Sea and East China Sea from different angles.
