摘　　要：广西沿岸的铁山港、廉州湾、钦州湾、防城港湾的潮流数值计算结果显示 ,4个海湾的落潮流均大于涨潮流 ,最大落潮流速 12 0 cm / s,最大涨潮流速 10 0 cm/ s。潮流为往复流型式 ,落潮由北向南 ,涨潮由南向北 ,流向具有明显的规律性 ,这与实测结果较为吻合。但在钦州湾口外 ,其流向较为杂乱 ,存在 2个互反方向的回旋式流动 ,究其原因 。The numerical calculation of tidal currents in four bays of Guangxi including Tieshan,Lianzhou,Qinzhou and Fangchenggang are dealed with The velocities of the ebb currents in these bays is greater than the flood currents The greatest velocities of ebb current and flood current are 120 cm/s and 100 cm/s respectively The tide is a type of reversing current in which the tidal current has obvious regularity,the ebb current flowing from north to south and the flood current from south to north,being in accordance with the survey data But the direction of the tidal current in the Qinzhou bay is unorderly There are two reverse spinning currents It may relate to the geographical environment in this bay
