摘　　要：本文采用不规则三角网格系统和有限体积法,建立半封闭海域品清湖避风塘的潮流数值模型,对品清湖避风塘的水体交换能力进行数值模拟研究。研究结果表明,潮位、潮流数值模拟预测值与实测值拟合较好,该海域水体交换能力较好,半交换期为20 d左右,水体自然交换需要60 d左右。In this paper,the irregular triangular grid system and finite volume method are used to establish the tidal current numerical model of Pinqing Lake typhoon shelter in semi closed sea area,and the water exchange capacity of Pinqing Lake typhoon shelter is numerically simulated.The results show that the predicted values of tidal level and tidal current by numerical simulation fit well with the measured values,the water exchange capacity of this sea area is good,with a half exchange period of about 20 days and a natural exchange period of about 60 days.
