中文摘要：

本文基于1960~1997年期间黄海表层溶解氧（DO）数据,研究了不同时期DO时空变化规律。结果表明：表层DO月均值呈现出一致的变化规律,DO最高值（6.73 m L/L）出现在3月,最低值出现在8月（4.90 m L/L）;不同时期季节变化规律为：春季〉冬季〉夏季〉秋季。就整个研究阶段而言,DO年际变化趋于稳定;在空间分布上,表层DO也呈现出明显的季节变化特征,总体呈现出北高南低,近岸高于远海的分布特征。冬,春季节因受黄海暖流影响具有相似的分布特征;夏,秋季节因太阳辐射和黄海环流的影响分布特征相似;表层DO与海表温度负相关,随PO_4-P、NO_3-N和SiO_3-Si浓度增大而上升。表观耗氧量（AOU）在整个研究阶段均值为-0.06 m L/L,呈现基本平衡状态。

英文摘要：

The spatial and temporal variations in surface dissolved oxygen（ DO） in the Yellow Sea during different periods were investigated based on DO data obtained from in-situ measurements made during year of 1960 ~ 1997. The results showed that： the monthly variations of surface DO in different periods exhibited similar trends,with the maximum（ 6. 73 m L / L） and minimum（ 4. 90 m L / L） values occurring in March and August,respectively; the seasonal variations during different periods all followed the order Spring Winter Summer Autumn. The annual variation in surface DO presented stable trend over the duration of the entire period. Spatial distribution of the surface DO also presented obvious seasonal variations; there was a decreasing trend from the western coastal waters to the east open sea and an increasing trend from southern to northern. The mean values and spatial distributions were similar in Winter and Spring due to the effects of the Yellow Sea warm currents,while in Summer and Autumn they were similar due to solar radiation and water circulation in the sea. The surface DO was negatively correlated with the surface sea temperature. However,it increased with the nutrient levels（ PO_4-P、NO_3-N and Si O_3-Si）. The mean apparent oxygen utilization（ AOU） was -0.06mL/L,which indicated that the AOU kept balance during the study period.
