| 摘 要： | 末次盛冰期结束、海侵开始后渤、黄、东海陆架潮汐、潮流的演变对该区泥沙的输运与沉积 ,以及海底地貌的形成、分布以及演变等具有深刻影响。文中数值模拟末次冰消期以来 4个特定时期 ,即比现在海面低 80 m、5 2 m、30 m海面以及全新世最大海侵时渤、黄、东海陆架的潮汐、潮流。根据不同时期的潮汐、潮流分布特征得出 ,末次冰消期以来渤、黄、东海陆架潮汐、潮流的演变过程大致以全新世最大海侵为界划分为两个阶段 :1全新世最大海侵前为渤、黄、东海陆架潮汐、潮流基本分布格局的形成阶段 ;2全新世最大海侵后 ,为基本分布格局的局部调整阶段。末次冰消期以来基本海岸轮廓的变迁是渤、黄、东海陆架区潮汐、潮流演变的主要控制因素

| Abstract: | The evolution of tides and tidal currents on the continental shelves of the Bohai Sea, Yellow Sea and East China Sea (BYECS) has deeply influenced the sediment transport and deposition as well as the formation, distribution and evolution of sea bottom topography since the Last Deglaciation (LD). The tides and tidal currents on the continental shelves of the BYECS at four special periods, i.e., at the sea levels standing at 80m, 52m, and 30m below present respectively, and at the Holocene transgression maximum (HTM), are simulated. The distribution features of tides and tidal currents at different periods show that the evolution process of tides and tidal currents on the continental shelves of the BYECS since the LD are mainly divided into two stages: (1) the formation stage of the general distribution pattern of the tides and tidal currents on the continental shelves of the BYECS before the HTM, and (2) the local adjustment stage of the general distribution pattern after the HTM. The great change of coastline since the LD is the dominant controlling factor of the evolution of tides and tidal currents on the continental shelves of the BYECS. |
