| 摘要: |
| 基于“油粒子”模型，建立了一个溢油输运归宿模型，结合FVCOM提供的流场数据及多年统计的平均风场结果，模拟了围头湾400t燃料油在静风、常风及不利风向下，一个潮周期内高潮、落急、低潮、涨急４个时段，共计12个工况下的油膜漂移路径和影响范围．计算结果表明，溢油事故发生后，油膜扫海范围及迁移路径与溢油发生时刻及风向密切相关．静风条件下，溢油运动主要受当地潮流影响，呈西北东南向往复运动．常风向下，发生在围头湾的溢油向西北方向扩展，抵达刘五店水域，并经北侧水道向翔安方向延伸．油膜影响范围最广，并向南蔓延，最远抵达大金门和小金门之间水域． |

| Abstract: |
| Based on oil particle model, an oil spill transport and fate model was established in the Weitou Bay, Xia-
men, by combining with tidal current field modeled by FVCOM and statistic average wind. Then the drift path and
the effect area of oil were simulated under the calm wind, the dominant wind and adverse wind conditions. Four
hundred tons of fuel oil was set as the initial spill to model the oil-spill diffusion process over 24h. The results show
that the sweep range and migration path of the spilled oil is closely related to the occurrence time and wind. Under
calm wind condition, the movement of oil spill is mainly influenced by the local tidal current. northwest-southeast
reciprocated. The spilled oil extended to the northwest in dominant wind, arrived at Liuwudian and entered in
Xiang'an direction by the north side of waterway. Under the dominate wind, areas affected by oil film expanded
the largest in 3 directions. Then the oil spread southward and arrived at Quemoy wateis. |
