| 摘 要： | 利用2007年厦门湾岸线和地形,对数学模型的参数进行验证,在验证结果达到规范要求的基础上,对厦门湾5个典型历史时期岸线和地形下的潮流场进行模拟计算,并根据数值模拟结果分析不同期间围（填）海工程对厦门湾潮流动力的累积影响.到2009年,通过嵩鼓断面和厦鼓断面的潮量分别减少了54.9%和24.5%,而通过同安湾湾口断面的潮量减少了23.7%.围（填）海工程对厦门湾湾内流速大小的影响比较明显,厦门西海域和同安湾海域的主要航道及湾口流速变化尤为明显.嵩鼓水道流速减少了40%以上,厦鼓水道流速减少了20%以上.结果表明：由于诸多围（填）海工程建设,致使海域面积大量缩小,进而引起了厦门湾纳潮量显著减少,潮流动力条件明显降低.

| Abstract: | The hydrodynamic numerical mode MIKE21 is used to simulate Xiamen Bay according to features such as its complex terrain,flexural coastline and large area of tidal flat.A two-dimensional mathematical model of tidal current in Xiamen Bay is presented in this paper.Observational data were used to verify the accuracy of the model.To reproduce the hydrodynamic environment for the five periods of 1955,1956,1970,1984 and 2009,the numerical experiment needs to be redesigned in terms of the boundary and hydrodynamic... |
