基于Mike21/3SA模块建立京杭运河苏北段溢油扩散数学模型，预测溢油突发事故油膜漂移轨迹和扩散范围。研究结果表明：水动力场、风场对内河溢油扩散有着重要的影响；流速对油膜的漂移过程起主导作用，油膜移动速度随着水流流速的增大而增大；不利风向作用下，油膜下游漂移影响范围明显增大；一旦发生漏油事故，应及时监测溢油河段水流状况与气象条件，及时采取应急救援措施。

Oil spill diffusion numerical simulation module was established based on Mike21/3SA module. The oil film trajectory and diffusion range were predicted in the oil spill accident. The research results show that:the oil spill trajectory is mainly influenced by current field and wind field. The oil film drift process is mainly influenced by flow velocity, and the oil film movement speed is increased with the increase of flow velocity. Against the wind, oil film drift downstream distance increases obviously. Once the oil spill occurs, water flow condition and meteoro?logical conditions should be monitored, and emergency rescue measures should be adopted in time.
