| 摘 要： | 本文分析该海域约７０个测站的温、盐资料，获得以下结果：（１）夏季在对马暖流的源区，于１０～７５ｍ水层内，其流路成一明显的分界线，左（西）侧温、盐度较低，右（东）侧温、盐度较高。（２）夏季对马暖流源区存在着三种海水：高温、高盐水，高温、低盐水和高温、次高盐水。（３）夏季朝鲜海峡地区，东水道的温、盐度高于西水道温、盐度。（４）１９８７年，东海黑潮区、长江口、杭州湾外及东海酉南部海域，夏季的表层盖度，皆比１９８９年同季、同一海域的盐度偏高；而对马暖流“东海段”却出现相反的低盐现象。其原因之一，１９８７年冲淡水势力极强，几乎盘踞了对马暖流源区的大部分海域，使源区盐度下降，并随对马暖流北上输送的缘故。其中：（１）和（４）两点认识系首次提出。

| Abstract: | In this paper, the observational data of Temperarure(t) and Salinity (S) collected at about 70 stations in the studied area are analysed and the main results are as follows: (1) at 10-75mm depth the path of the Tsushima Warm Current (TWC) became a clear demarcation line in the source area of TWC in summer:t and S were lower on the left (west) side of the line and higher on the right (east) side; (2) There exist three kinds of water in the source area in summer: high t and high S water, high t and low S water,and high t and sub-high S water; (3) t and S in the east channel of the Korea Strait were higher than those in the west channel in summer; (4)Taking 1987 as an example, the surface S in the summer of this year in the Kuroshio area of the East China Sea, the Changjiang River mouth, the outSide of Hangzhou Bay and the area southwest of the East China Sea, was higher than that of 1989 in the same sea areas, whereas the S in the TWC area was lower. One of the reasons for this was that the sphere of influence of the diluted water was quite larse and nearly covered moot of the source area,.Thus causing S in this area to decrease. Of the above--mentioned results, the first and the fourth are present6d for the first-time. |
