摘　　要：根据唐山三岛海洋站2019年1月-2020年12月期间整点的实测表层海水温度、表层海水盐度等水文要素数据资料,对其月平均、年平均、年最高值和年最低值进行了特征分析。分析结果表明:唐山三岛海洋站的表层水温具有明显季节性变化特征,春季、夏季明显升温,夏季达到最高温度,秋季开始进入快速降温期,冬季水温达到最低;表层海水盐度呈现“两峰一谷”等变化特征;表层海水温度和表层海水盐度年际变化均较小。according to the measured data of hydrological elements such as surface seawater temperature and surface seawater salinity at Tangshan Sandao ocean station from January 2019 to December 2020, the characteristics of monthly average, annual average, annual maximum and annual minimum are analyzed. The results show that the surface water temperature of Tangshan Sandao ocean station has obvious seasonal variation characteristics. It rises significantly in spring and summer, reaches the highest temperature in summer, enters the rapid cooling period in autumn and reaches the lowest in winter;The surface seawater salinity presents the characteristics of "two peaks and one valley";The interannual variations of surface seawater temperature and surface seawater salinity are small.
