摘要:
以泉州湾秀涂人工岛的建设为例,基于有限体积海岸海洋模型,建立泉州湾三维数值模型,模拟分析建岛前、后水动力特征、潮致余流和纳潮量的变化.采用欧拉弥散方法模拟污染物浓度的对流扩散,对泉州湾的水交换能力进行分析.结果表明:建岛后,大部分海域的海潮流速约减小0.1 m·s-1;石湖港区人工岛连线以西大部分区域的潮致余流变化不显著,但湾口的潮致余流出现较为明显的减少;纳潮量的变化较为明显,小潮期间纳潮量的变化率为10.09%,使小潮期间湾内水体与外海的交换能力变弱,更易遭受污染威胁;洛阳江流域和金屿的污染物浓度差变化较大,导致湾内水体的半交换时间约增加3 d.
Abstract:
Taking the construction of the Xiutu artificial island in Quanzhou Bay as an example, a three-dimensional numerical model of Quanzhou Bay was established based on the finite-volume coastal ocean model, and the changes of hydrodynamic characteristics, tidal residual current and tidal capacity before and after the construction of the island were simulated and analyzed. Euler dispersion method was used to simulate the convection and diffusion of pollutant concentration, and the water exchange capacity of Quanzhou Bay was analyzed. The results showed that after the construction of the island, the tidal velocity in most of the sea area was decreased about 0.1 m·s-1. The tidal residual current in most areas of the west of the artificial island line in Shihu Port area did not change significantly, but decreased markedly in the bay mouth. The change of tidal capacity was obvious, and the change rate of tidal capacity was 10.09% during neap tide, which weakened the exchange capacity between the water in the bay and the open sea during neap tide and made it more vulnerable to pollution. The difference of pollutant concentration between Luoyang River basin and Jinyu was large, which led to the increase of half exchange time of water in the bay by about 3 days.
