中文摘要：基于Delft3D模型建立湛江湾海域水动力数值模型,并通过实测水文数据对计算值验证基础上考虑溢油漂移、扩散、蒸发、乳化、吸附等过程建立湛江湾海域溢油扩散数值模型,对不同潮时(涨潮、落潮)与不同风况(静风、夏季常风、冬季常风、两种不利风况)下发生的原油泄漏事故进行溢油漂移扩散数值模拟,预测分析溢油24 h内油膜漂移扩散分布、累积扫海面积、油膜到达环境敏感区的时间以及岸线吸附分布图。分析结果表明:油膜的漂移扩散主要受潮流与风况共同影响,油膜的长期扩散方向与风向一致;溢油事故发生24 h内只有在不利风况条件下会对南三岛红树林保护区与渔业养殖区产生影响;特呈岛海洋保护区最易受污染威胁;静风条件下溢油影响范围最广,涨潮静风工况下24 h后油膜扫海面积最大,溢油影响面积达到57.89 km;油膜最易在湛江湾顶岸线受到吸附。

外文摘要：A hydrodynamic numerical model of the Zhanjiang Bay area is established using the Delft3 D model and the calculated value that was verified with the measured hydrological data.On the basis of the hydrodynamic model,a numerical model of oil spill diffusion in Zhanjiang Bay is established by considering the processes of oil spill drift,diffusion,evaporation,emulsification and adsorption.The oil spill drift and diffusion numerical model simulates the oil spill accidents under different tides(flood,ebb) and different wind conditions(no wind,summer constant wind,winter constant wind and two unfavorable wind conditions) and predicts the main drift path,sea sweep area and the time of oil film to reach environmental sensitive area within 24 h of oil spill.The analysis results show that the oil film drift and diffusion are mainly related to the current field and wind conditions,and the long-term diffusion direction of the oil film is consistent with the wind direction.Within 24 hours of the oil spill,only unfavorable wind conditions would affect the mangrove protection area and fishery aquaculture area in Nansan island.Marine reserve in Techeng island is the most vulnerable to pollution.Under the condition of calm wind,the affected area of oil spill is the widest.Under the condition of flood tide and calm wind,the area of oil film sweeping the sea after 24 hours is the largest,and the affected area of oil spill reaches 57.89 km~2.The oil film is most easily adsorbed on the top shoreline of Zhanjiang Bay.
