| 摘 要： | 以溶解态的保守物质作为示踪剂，建立茅尾海水交换平面二维数学模型，采用开边界污染物浓度梯度与内侧一致假定考虑了边界污染物回归，计算分析了钦州湾湾口两侧大范围填海工程对茅尾海纳潮量和水体半交换周期的影响情况。研究表明：龙门海峡通道顺畅是维持茅尾海纳潮量的关键因素，湾口宽度保持9.4 km以上茅尾海内纳潮量和水体半交换周期基本不受湾口填海工程影响。

| Abstract: | The two-dimensional mathematical model for water exchange in Maowei sea is established using the dissolved conservative material as the tracer. The pollutions are fed back at boundary under assumption that the gradient of pollutant concentration is the same both inside and outside the boundary.Based on the validation of the mathematical model,the effect on the volume of tidal prism and water change of Maowei sea is calculated and analyzed by the reclamation of the Qinzhou bay mouth.Results indicate that the width of Longmen strait is the key factor for keeping the volume of tidal prism of Maowei sea.The reclamation engineering in both sides of Qinzhou bay mouth keep the width over 9.4 km and has little effect on the water half-exchange period and the tidal prism of the Maowei sea. |
