| 摘 要： | 以１９８７年５—６月中日台作黄东海域综合调查的溶解氧资料为主，探讨调查海区溶解氧分布特征与水团的对应关系。指出：近岸水团溶解氧合量高，远海低；上层水团高，下层低。在黄海冷水和东海北部底层冷水的上界出现明显的溶解氧垂直分布最大值及封闭形高氧区。水团边界区，氧跃层明显。溶解氧含量变化与水团温盐特性有关。通过分析发现，溶解氧对鉴别次表层以深各水团，特别对鉴别东海次表层水及黑潮次表层以深各水团，可作为一种有效的指标。

| Abstract: | Based on the dissolved oxygen data obtained during the Sino-Japan Joint Survey in the Yellow Sea and East China Sea from May to June 1987 and other data, the relationship between the distribution of dissolved oxygen and water masses in the survey area are discussed. The results show that oxygen content is high in inshore water masses and low in off coast water masses, and it is high in upper layer water masses and low in under layer water masses. For water masses containing waters of the Yellow Sea Cold Water or the bottom cold water of the northern East China Sea, the dissolved oxygen appears to be maximum vertically at the upper bound and there is a closed zone of high oxygen. A spring layer of oxygen is obvious at the boundary of such water masses. The variation of oxygen content is related to the variations of temperature and salinity. The distribution of oxygen is controlled by the distribution and division of water masses index to differentiate water masses under the subsurface layer, specifically water masses under the subsurface layer if the East China Sea and water masses under the Kuroshio suburface layer. |
