以 1 975～ 1 999年夏季东海标准断面观测资料为据 ,把东海 30°N断面的盐度分布态势划分成 4个类型 ,并以 1 975～ 1 985年的大面资料为主 ,初步讨论了对应于这 4个类型的长江冲淡水扩散形态与台湾暖流水的强弱、位置等的关系。结果表明 :多数分布类型都具有代表性的冲淡水分布态势 ;长江冲淡水的扩散形态似与台湾暖流的北伸强弱、离岸远近、离表面的深浅有较密切的关系。
Based on the data of summer standard sea section in the East China Sea from 1 975 to 1 999, the salinity distribution of the 30 ° N section in the East China Sea is divided into 4 types and the data of the large surface area from 1755 to 1 985 are mainly discussed Corresponds to these four types of the Yangtze River, the spread of fresh water and warm water in Taiwan’s strength, location and so on. The results show that most of the distribution types have a representative flushing water distribution pattern. The diffusion pattern of red water in the Yangtze River seems to be closely related to the northward extension and weakness of Taiwan’s warm current, the distance to offshore and the depth of the surface.
