摘　　要：为更好地理解油与颗粒物的碰撞聚合过程及溢油沉底后的行为归宿,以近年来渤海海域不明油污上岸事件为研究背景,阐述悬浮颗粒物作用下海洋溢油的沉降机理,重点分析油品和悬浮颗粒物物化特征、油品和悬浮颗粒物浓度、海水盐度及混合能对OPAs形成的影响。基于实验室和溢油现场的研究成果提出进一步需要探究的问题,为沉底油污染的应急决策、追踪预测和损害评估等方面提供参考。In order to better understand the collision and aggregation between oil and particles as well as the behavior of spilled oil after settling,the settling mechanism of spilled oil under the action of suspended particulate matter was expounded in view of the incident of unidentified oil sources coming ashore in Bohai sea in recent years.The effects of physicochemical characteristics and concentration of oil and suspended particles,salinity and mixing energy on the formation of OPAs were significantly analyzed.Based on the research results of laboratories and oil spill sites,problems requiring further exploration were identified.The work can provide references for emergency decision-making,tracking prediction,and damage assessment of sunken oil pollution.
