摘　　要：基于FVCOM建立胶州湾的三维水动力模型,考虑风场作用构建一套FVCOM-GNOME-ADIOS相耦合的溢油模拟预测系统,利用此系统对黄岛"11.22"管道泄漏爆炸事故引发的溢油情境进行数值模拟,得到真实环境中溢油漂移路径、扫海范围和风化过程,并对模拟结果了进行验证。结果表明,该预报方法可以较好地进行溢油事故反演。溢油3天后的主要风险海域为跨海大桥以南胶州湾海域和薛家岛海域,对大石头西岸侧、团岛东岸侧及薛家岛南岸侧3条岸线污染最严重,扫海面积达73.24km2。为期5天的溢油风化损失量约为26.76%,其中蒸发量占25.4%。溢油发生后第一个小时是进行溢油应急处理的关键时间,可以有效阻止溢油扩散面积增大,减小污染海域范围。Based on the finite-volume coastal ocean numerical model （FVCOM）, a three-dimensional shallow-sea tidal model was established for Jiaozhou Bay. Considering currents modeled by FVCOM and real wind, a model-forecasting system was built by combining FVCOM, GNOME and ADIOS to forecast the fate and behavior of spilled oil, which has been applied in the oil spill accident induced by Huangdao pipeline leakage at Jiaozhou Bay on Nov 22, 2013. The oil-spill track, sweeping range and weathering process under real environment were obtained and comparisons between simulations and observations were done. The results showed that the method can display the oil spill inversion well. In addition, the most risky areas after 72 hours were related to the south of cross-sea bridge of Jiaozhou Bay and Xuejia Island, the most polluted coastlines included the western bank of Dashitou, the eastern coast of Tuandao and the southern coast of Xuejiadao, and sweeping area was about 73.24 km2. The weathering loss for 5 days accounted for 26.76%0, of which loss of evaporation accounted for 25.4%. The first hour after the oil-spill occurred was vital for oil spill treatment; it can effectively prevent the oil spill area, reducing pollution area thus.
