北黄海庄河养殖海域污染物运动轨迹数值模拟

摘要

The three-dimensional current model of FVCOM (Finite Volume Coast and Ocean Model) coupled with the la-grangian particles tracing module is used to investigate the hydrodynamic characteristics, pollutant transport at Zhuanghe aquaculture waters of northern Yellow Sea. The FVCOM model is based on the finite volume method with the unstructured triangle grids. By simulating the trajectories of particles discharged into Zhuanghe aquaculture waters, it can be seen that the water exchange capacity is strong at southwest waters and the water exchange capacity is weak at northwest waters of Shicheng island, the pollutant transport capacity is strong at east waters of Shicheng island far away from coastline, the calculated results can provide the basis for the evaluation of water body environment at Zhuanghe aquaculture waters.%基于有限体积法和非结构化三角网格的FVCOM （Finite Volume Coast and Ocean Model）三维潮流模型，耦合拉格朗日粒子追踪模块，对北黄海庄河养殖海域的水动力特性和水体污染物的运动轨迹进行了计算。通过模拟庄河养殖海域投放特征粒子的运动轨迹发现，石城岛西南侧养殖海域水体交换能力较强，东北侧养殖海域的水交换能力较弱，而离岸线较远的石城岛东侧养殖海域污染物的输移能力较强，研究结果对该养殖海域的水体环境评估有重要意义。
