摘　　要：对1995年-2005年国家海洋局连云港海洋环境监测站的溶解氧等数据进行了分析,结果表明,连云港东西连岛附近海域表层溶解氧含量多年来呈现增加的趋势,同时冬季平均含量高于春季,春季高于秋季,而夏季最低;东西连岛附近海域表层溶解氧含量与表层水温呈现良好的线性负相关关系,据此相关性可以获取表层溶解氧含量的动态变化值;此外,东西连岛附近海域表层溶解氧过饱和程度在2000年之后呈加剧趋势。The dissolved oxygen（DO） content in surface seawater from 1995 to 2005 at Dongxi Lian Island Ocean Environment Monitoring Station of State Oceanic Administration （SOA） was analyzed. The results show the DO content showed an increasing trend in those years, and the DO content was different in different seasons. Winter had the highest concentration and was greater than spring, fall, and summer, respectively. There was a negative correlation between the DO content and the surface seawater temperature, and the dynamic data of the DO content in surface seawater could be obtained according to this relation. In addition, the supersaturation of DO showed an increasing trend near the sea area of Dongxi Lian Island after 2000.
