摘　　要：运用Backhaus的三维非线性模型，同时考虑潮、风和台湾暖流的作用，本文计算了夏季我国东海沿岸上升流。结果表明，东海沿岸从杭州湾口外一直到闽北的海底坡折区上存在明显的上升流，它是带状分布，宽约40km，舟山近海的强上升流出现在30m层，向南则可达到较深的水层，流速一般为6．5×10－3cm／s。The upwelling in the coastal areas of the East China Sea is computed by using Backhaus's 3-D numerical model. Jt is found that there exists a coastal upwelling stripe off Fujian and Zhejialig with a widtll of 40km or so, and the computed largest upwelling, 6.5×10-3cm/s, occurs at 30m off the Zhoushan lslands and between 30m and 40m off south of the islands.
