| 中文摘要: |
| 采用MIKE21-HD软件建立了大小鱼山海域潮流数值模型，并利用实测资料对其进行验证。在模型基础上，针对大小鱼山海域岛间的复杂潮流条件，利用潮流数值模拟分析大小鱼山围垦工程对周边水动力条件的影响。模拟结果显示：1）围垦工程的影响范围主要集中于围垦区附近，未对大范围海域水动力条件造成影响，潮平均流速变化基本在0.5 m/s以内。2）在围垦区东西两侧弱流区产生1.5～2 m/a的淤积，其余水域海床冲淤幅度基本在1 m/a以下。因此，该围垦工程实施是可行的。 |

| We employ the 2D tidal current numerical model （MIKE21-HD） to build a current model in the Da-xiao-yushan water area，which is validated by observed data. In view of the complex tidal current conditions between islands in Da-xiao-yushan water area，the influence of the reclamation project on the surrounding hydrodynamic conditions is simulated by using the numerical simulation of the tidal current based on this model. The simulation results show：1）The influence scope of the reclamation project is mainly concentrated in the vicinity of the reclamation area，without affecting the hydrodynamic conditions of the large-scale sea area. The average tidal velocity change is basically within 0.5 m/s. 2）1.5～2 m/a siltation occurs in the weak current areas on the east and west sides of the reclamation area，and the seabed erosion and siltation rate in the remaining waters is basically below 1m/a. The reclamation project is feasible. |
