摘　　要：吴淞站是黄浦江入长江口重要的水文站,吴淞站的潮位预报对于太湖流域防洪及水资源配置工作具有重要的意义,也是上海市城市防洪的重要基础工作之一。文中首先对吴淞潮位站进行固定分潮的调和分析,再根据潮汐资料推求各分潮的调和常数,从而得到天文潮的预报方程。验证结果表明,预报方程具有精度高、速度快、简便实用等优点,适合于上海市吴淞站天文潮的推算。The tide prediction at Wusong Hydrological Station, a crucial hydrological station at the Huangpu Estuary, is not only fundamental to the flood control for the city of Shanghai, but also significant to flood control and water resources allocation in Taihu Basin. According to the tidal data at Wusong Station, the harmonic constants of the selected tidal constituents are calculated with harmonic analysis, and then used to form the prediction equation of the astronomic tide. The verification results show that the prediction equation is well established for its high accuracy, calculating speed and convenience, and it is suitable and practical for the calculation of astronomic tide at Wusong Hydrological Station.
