摘　　要：本文根据数值计算结果,分析了钦州湾潮汐和潮流的变化特征。结果表明该湾的潮波运动属于驻波式振动;西部沿岸的流速比东部弱,在龙门港口门附近可达70厘米/秒;其落潮流速比涨潮流速大。Based on the results of numerical computation, the distribution characteristics of tide and tidal current in Qingzhou Bay have been analyzed. The results show that: (1) the difference between time of high water and time of the maximum tidal current is 1/4 cycle and the motion of tilal waves belong to vibration of standing wave; (2) the velocity of tidal current in the west coast is weaker than that in the east:While the velocity near Longmen Harbor has its greatest value at 70 cm/sec; (3) the velocity of ebb current is larger than that of flood current.
