摘　　要：基于渤海三维温-盐-流动力学模型,依据沉潜油的沉潜特性,建立了基于拉格朗日追踪的渤海沉潜油模型,对渤海不明来源沉潜油的迁移运动规律进行模拟和统计分析.结果显示该模型实现了对渤海沉潜油来源的定量分析,进而探讨季节尺度上秦皇岛沿岸沉潜油的局地与远程来源的关系,由此解析春末夏初秦皇岛海域出现沉潜油上岸的机制,为渤海不明来源沉潜油的监视和防控提供了参考依据.A Lagrange model tracking submerged oil movement was built based on a three dimensional thermo-saline-dynamic numerical model,which includes the sinking and suspending process of the submerged oil.The model was applied to simulate and statisticly analyze source-unknown submerged oil movement in the Bohai Sea.Using this model,the source of submerged oil was analyzed quantitatively,and the relationship between local and remote sources of submerged oil along the Qinhuangdao coast was clarified on a seasonal scale,which helped to explain mechanisms of the occurrence of submerged oil along the Qinhuangdao coast in late spring and early summer.The result provided objective references for monitoring,preventing and controling source-unknown submerged oil in the Bohai Sea.
