摘　　要：海水盐度是海洋物理环境的重要组成部分,其变化可改变水动力环境,进而改变海洋生态环境,因此研究海水盐度的变化特征具有十分重要的意义。文章对2011-2015年日照海洋环境监测站海域表层海水盐度的实测数据进行统计分析,研究结果表明:该海域表层海水盐度基本围绕多年平均值呈周期性波动;受季风影响,表层海水盐度呈显著的季节变化特征,即冬、春季高,而夏季最低;降水量对表层海水盐度的影响有明显的滞后性;冬季表层海水盐度有升高趋势。Seawater salinity is an important part of the marine physical environment.Changes in salinity can change the hydrodynamic environment,and the marine ecological environment accordingly.It is of great significance to study the changes of salinity.This paper analyzed the real-time salinity data of Rizhao Marine Environmental Monitoring Station from 2011 to 2015,finding that the seawater salinity in Rizhao sea area had a significant seasonal variation.The salinity was highest in spring and lowest in summer.The influence of precipitation on salinity had a significant hysteresis,and the salinity of this sea area had an increasing trend in winter.
