Using harmonic analysis of the calculated tidal level and current, the distributions of co-tidal lines for K1, O1, M2 and S2 are obtained, whose maximum amplitudes can reach 112 cm, 96 cm, 50 cm and 15 cm, respectively. The distribution of the maximum probable current velocities in Qinzhou Bay is basically the same as that of isobaths, and the maximum probable current velocity can reach 200cms^(-1) nearby the Longmen Harbor. It is concluded by the analysis of K1 and M2 tidal current ellipses that the flow is rotating at the mouth of the bay, while its retilinear flow is in the nearshore area, estuaries and channels. The distributions of the major axes are closely related to the topography, and the rotation directions of both constituents are clockwise.
