摘　　要：长江口是我国通航密度最高的水域质疑,也是上海市重要水源地——青草沙水库的所在地。长江口发生溢油事故的潜在风险较大,研究区域内船舶溢油对溢油应急处置具有重要的显示意义。该文运用MIKE21SA模型建立长江口杭州湾二维溢油数值模型,针对5·18溢油事故进行后评估,并借助6种不同工况的模型,研究了溢油扩散的影响因子,讨论了长江口区域溢油事故对青草沙水源地的潜在影响。The Yangtze Estuary is one of water areas which have the highest navigation density in China. Here is important Shanghai water resource area,named Qingcaosha Reservoir. Considering large potential risks of oil spill accident in Yangtze Estuary,to study oil spill in the area has important practical significance for oil spill emergency disposal. In this study,the basic principles of simulation of oil spills were introduced. A two-dimensional numerical model of oil spill in Yangtze Estuary-Hangzhou Bay was built by MIKE21SA. The 5. 18 oil spill accident was assessed by the model. According to the simulation of 6 kinds of different working conditions,the impact factors of oil spill were analyzed. The potential impact of oil spill accident in Yangtze Estuary on Qingcaosha Water Source was discussed.
