| 摘 要： | 本文运用一个含动边界的二维河口海岸动力模型模拟了湄洲湾潮汐潮流的基本特征，模拟结果与实测数据吻合较好．在此基础上估算了湄洲湾大、小潮过程的纳潮量，并根据湾内保守示踪物的质量（浓度）随涨、落潮流周期性的变化，进一步估算了湄洲湾的水交换周期，其半交换和80％的交换周期分别为5d和15d．同时可以看出，主航道深水区的水交换特性明显强于湾顶浅水区． |

| Abstract: | A 2-D estuarine coastal ocean model （ECOM） with moving boundary is used to reproduce the tidal regime in Meizhou Bay. It shows that simulation results agree well with the observations. Based on the validated simulations, the tidal prism and water exchange period are further estimated. With conservative tracer method, it is found that the half and 80% of water exchange period are 5 and 15days ,respectively. Additionally ,the water exchange is strong in the sea-route, while it is relatively weak in the end of the bay or on tidal fiats. |
| Keywords: | Meizhou Bay numerical model tides and tidal currents water exchange |
