摘　　要：在溢油运动模型分析的基础上,确立遥感数据服务于应急所需的时间分辨率,并进一步分析遥感数据处理时间构成,讨论应急反应下的溢油轨迹预测、遥感监测技术的协同,提出优化建议。研究成果在2010-07-16发生的大连新港溢油事件发挥了关键作用,结果表明溢油应急遥感应用时效具有实践可行性及重要性。Time is a critical factor in the response of oil spill emergency because the oil spilled in the sea can rapidly be diffused to a large area by winds and currents in a short time. Since the models for oil-spill traj ectory have uncertainties and some key parameters influencing the accuracy of prediction, e.g. the oil-spill area and position, can change with time, the data from remote sensing are mostly needed. The prediction of oil-spill trajectory and the cooperation with remote sensing techniques are discussed for the response of oil spill emergencies. Based on a model analysis of oil-spill motion, the time resolution needed for the re sponse of oil spill emergencies and resulted from the remote sensing data is determined, a method for re- mote sensing application time is further described and then an optimized proposal is put forward for the time processing by using remote sensing data. This result played a key role in the oil spill event that hap- pened in the Dalian Xingang Port on July 26, 2010. It has been showed that the application of remote sens- ing data for the time effectiveness of oil-spill emergencies is practical and significant.
