| 摘 要： | 依据中国和挪威联合进行的黄东海渔业资源声学评估调查资料，并结合历史研究成果，分析了对鱼行动分布有着显著影响的三大水系（黄海冷水团、黄海暖流和苏北沿岸冷水）的变化特征。结果表明，三大水系均具有明显的年际变化。（1）黄海冷水团的温盐性质比较稳定，但其相对体积强年（1986年11月）约为弱年（985年11月）的144倍；（2）黄海暖流的流速强年（1986年1月）约为弱年（1992年正月）的1．21倍；（3）苏北沿岸冷水以3月份势力最强，其强度1985年1月大于1986年1月。

| Abstract: | This study on the vartalion Charcteristics of the Yellow Sea Cold Watermass(YSCW),Yellow Sea Warm Chrrent(YSWC)and Subei Cold bo Water(SCCW)in autumnand winter,which hav remarkable influence on the behavior and disribution of anchovy indicated that the foree larg water systems had distinct annuai variations tal that: (1)The YSWC temperature tal salinity were stable, but its volume in the stronger year (Nov., 1986) was 4. 44thoes tha in the weaker year(Nov.,1985); (2)The YSWC current speed in the stronger year(Jan,1986)was 1. 21 times that in the weaker year(Jan,, 1992); (3)The SCCW was strongestin March,stronger in January, 1985 than it was in January, 1986. |
