摘　　要：台湾海峡有多个上升流区存在，其中西部海区的海坛岛东、东山岛 东南和台湾浅滩南部外区三处上升流最活跃和持续时间最长。本文依据 １９８３ 至１９８９年期间在台湾海峡西部和中部的三次海洋综合调查资料，着重探讨 了上述三处上升流出现和消失的时间冷水中心位置，指出它们共同特征是每 年出现的或消失的时间基本稳定不变，并随北向海流和风要素的变化而长 消。There are several upwelling areas in the Taiwan strait,some of them being the most active for the longest time. They are respectively located at: 1 ) The east sea atea of the Haitan Island, 2) The eastsouth sea area of the Dongshan Island and 3) The south sea area off the Taiwan shallow. According to the investigatory data obtained during 1983 to 1989 (3 times) at the west and middle parts of the Taiwan strait, the appearance and disappearance time, the cold centre position of the three upwelling areas are probed in this paper. Their characterastics are followed: 1. The time of their appearance and disappearance in each year are stable basically; 2. Their growing and decline are decided by the northward current and wind elements.
