摘　　要：通过对岙山岛西南侧附近海域的水文调查,分析了该调查海域潮汐潮流特征,结果表明:调查海域潮汐类型为规则半日潮;潮差较大,临时潮位站平均涨潮历时低于平均落潮历时。潮流类型为不规则半日浅海潮流,潮流运动形式以旋转流为主;流速相对较小,落潮流速大于涨潮流速;涨潮流向集中在西北偏西至北之间,落潮流向集中在东南至南之间。Through the hydrologic survey of the sea area near the southwest side of Aoshan island,the tide and tidal current characteristics are analyzed,and the results show that:the tide is regular semidiurnal tide;the tidal range is significant,and the average duration of flood at the temporary tide station is lower than that of ebb.The tidal current is irregular semidiurnal shallow current,the tidal movement is mainly in the form of rotating flow;the flow velocity is relatively small,ebb current is greater than flood current;flood current direction is concentrated between west-northwest and north,ebb current direction is concentrated between southeast and south.
