摘要
本文利用1975—1981年东海断面调查资料,分析了东海西北部海域(北纬28°—33°,东经125°以西)盐度锋的分布特征及其变化,指出了该区盐度锋终年存在,且有明显的季节变化和年际变化,影响盐度锋分布和变化的主要因子是台湾暖流的强弱、径流量的多寡以及浙江沿岸上升流的盛衰,盐度锋的位置与邻近海域渔场的关系密切,中心渔场一般位于盐度锋的外海侧。
Based on the observation data from 1975-1981 year in the East China Sea, the distribution characteristics and variation of the salinity front was analysed in the northwestern region (28°-33°N, west to 125°E) of the East China Sea. It was showed that there was the salinity front all the year round, and it had a obvious variations in both season and year after year. The main reason for influencing on distribution and variation of the salinity front was Taiwan warm current, discharge and the coast upwelling current off Zhejiang.
The position of the front was closely related to centre fisheries in the northwestern region of the East China Sea. They are located in the offshore side of the front.
