摘　　要：海洋观测是研究近海水动力环境的一个重要手段,为了研究海南岛西南海域的潮流和潮汐特征,在研究海域进行了大、中、小潮期间的潮位和潮流观测,基于实测资料,分析研究了该海域的潮汐和潮流特征。分析结果显示:该海域外海潮汐性质为不规则全日潮而近岸为规则全日潮;观测期间实测最大流速为1.57 m/s,余流最大为0.20 m/s;10个观测站位处,计算所得最大可能流速为2.58 m/s;各主要分潮流基本以O1和K1全日分潮流为主,不同层次潮流椭圆的旋转方向顺时针旋转与逆时针旋转数目基本相等。该研究成果对于该海域的水动力环境研究具有重要意义。In-situ observation is an important method to study the ocean dynamical environment. In order to study the characteristics of tide and tidal current at the southwest of Hainan Island, the tide and tidal current observations were carried out during the large, middle and neap tide times in the studed area. Based on the observed data, tide and tidal current characteristics in the study area were analyzed. The results show that it is irregular diurnal tide off the coast and regular diurnal tide along the coast. The measured maximum current speed was 1.57 m/s, and the residual current could reach 0.20 m/s. The calculated maximum probable velocity of the current is 2.58m/s among the 10 stations, and the main component of the tidal current is O1 and K1. The rotation direction of the tidal current component at different levels can be clockwise and counterclockwise, which are basically the same proportion. The findings in this paper have important implications for the study on hydrodynamic environment at this area.
