| 摘 要： | 阐明渤海环流和潮余流的分布特征及其与沉积物输运之间的关系。本文根据８０年代以来的实测海流资料得到：辽东湾的环流是顺时针向的；黄河三角洲外海存在着一支流向东北偏北向流，与辽东湾西部的东北向海流相接；渤海湾内的环流北部为反时针向，南部为顺时针向回转的双环结构。上述环流趋势与渤海沉积物分布相一致。渤海沿岸主要入海河流的特征矿物分布正在上述环流存在的最好佐证。文中进一步讨论了潮余流分布特征及其对渤海环流的

| Abstract: | Distribution characteristics of circulations and tidal residual currents and their relations to sediment transport in the Bohai Sea are discussed, and numerical models of circulations in this sea at present are also reviewed. Current data measured from the eighties at the oil platforms and other places show that the circulation in Liaodong Bay is clockwise, that in the offshore areas of the Huanghe River Delta is a current directed northeast by north and joined to the northeastward current in the western part of Liaodong Bay and that the circulations in the Bohai Bay are anticlockwise in the northern part and clockwise in the southern part. Most numerical models of the Bohai Sea circulations at present do not conform to the above results. The Eulerian and Langrangian residual currents are also discussed on the basis of results of numerical model of tide and tidal current. It was found that the Eulerian and Langrangian tidal residual current form a large clockwise circulation in the central part of the Bohai Sea and Liaodong Bay. This circulation is very consistent with the circulation pattern from the Huanghe River Delta to Liaodong Bay and means that the tidal residual currents contribute importantly to the Bohai circulations. It is further pointed out, for the first time that the circulations of Bohai Sea are consistent with the sediments distribution in the Bohai Sea. In fact, the distribution of typical minerals of the sediment discharge from main rivers flowing into the Bohai Sea is the best evidence for existence of Bohai circulation given above. |
