采用非结构有限体积近岸海洋模型(finite volume coastal ocean model，FVCOM)，对渤海潮波系统进行1年的数值模拟．分析了不同底摩擦系数对渤海潮波系统数值模拟的影响，并选取潮波系统误差较小的结果，进行15天、1月和1年的调和分析，以比较不同调和分析时间对结果准确性的影响．结果表明：模拟结果与实测调和常数分布有较好的一致性；开边界条件一定，当底摩擦增大时整体海域振幅值相对减小，无潮点也向潮波传入方向左偏；底摩擦系数为0.002时潮波系统整体模拟结果较好；调和分析的时间不宜少于1月．

FVCOM(finite volume coastal ocean model)was applied in this research to the simulation of the Bohai tidal system for a period of 1 year. The effects of bottom friction coefficients on the Bohai tidal system simulation were analyzed. Harmonic analysis was performed every 15 days,1 month and then 1 year in order to know the differences caused by the length of time. The results indicate that the simulated and observed harmonic constants are consistent with one another. When the open boundary conditions were the same,the amplitudes of the tide in the entire sea waters decreased as bottom friction increased. Also,the amphidromic point drifted left along with the direction of the tide propagation. The simulation systems gave better results when the bottom friction coefficients was 0.002. The time of the harmonic analysis should not be less than 1 month.
