根据台湾海峡南部 ２ 个定点多周日观测站 １９９７ 年 ８ 月的 Ｃ Ｔ Ｄ 资料，进行温、盐垂直分布时间变化的分析，结果表明：二测站调查期间基本上都存在温、盐跃层，跃层的强度和深度随时间变化较大，显示出较为复杂的温、盐垂直分布，与多种水系在此交汇有关．但二测站的下层稳定地存在低温高盐的海水，有向上涌升的趋势，并受潮流的影响，可见其所在的海域应为上升流区 Based on the C T D data of 2 fixed-point multi-Sunday observatories in southern Taiwan Strait in August 1997, the vertical distribution of temperature and salt was analyzed. The results show that during the survey period, there are basically temperature and salt thermocline The intensity and depth of the thermocline vary greatly with time, showing a more complex vertical distribution of temperature and salt, which is related to the intersection of various water systems. However, the low temperature and salty seawater stably exists in the lower part of No.2 station and tends to rise upwards. Affected by the tidal current, it can be seen that the sea area where it is located should be an upflow zone
