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 trajectory 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 response of oil spill emergencies and resulted from the remote sensing data is determined, a method for remote 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 happened in the Dalian Xingang Port on July 26, 2010. It has been showed that the application of remote sensing data for the time effectiveness of oil-spill emergencies is practical and significant.
