| 摘要: |
| 渤海海域溢油事件频发，所以进行海洋溢油风险时空特征分析，对于开展卫星遥感溢油精确监测具有重要意义。作者采用多源高分辨率卫星遥感数据，提取渤海海域船舶及石油平台两类主要溢油风险源分布状况，结合2015-2020年间渤海海域海上溢油卫星遥感监测结果，分析多种传感器下不同类型溢油的成像特征，通过溢油风险源核密度分析方法，获得海洋溢油事件发生的时空分布，实现渤海海域溢油风险程度综合评价。以2020年大连近岸海域溢油遥感监测为例，开展溢油扩散范围长序列应急监测，结合事故发生海域船舶航行风险源信息，对溢油事件发生过程进行回溯，实现对溢油发生源和分布面积的长序列准确监测。 |

| Abstract: |
| Oil spill events frequently occur in the Bohai Sea area. It is of great significance to analyze the temporal and spatial characteristics of oil spill risk for the accurate monitoring of oil spills by satellite remote sensing. The distribution of two main types of oil spill risk sources-ships and oil platforms in Bohai is extracted using multisource high-resolution satellite remote sensing data. Combined with the monitoring results of oil spill satellite remote sensing in Bohai from 2015 to 2020, the imaging characteristics of different types of oil spills under various sensors are analyzed. So, the temporal and spatial distribution of oil spill events is obtained through the core density analysis method based the above analysis results. The comprehensive evaluation of the oil spill risk degree in Bohai is realized in the end. Taking the remote sensing monitoring of the oil spill in the Dalian coastal waters in 2020 as an example, the long-sequence emergency monitoring of the oil spill spread range is conducted. Combined with the information of ship navigation risk sources in the accident area, the occurrence process of the oil spill is traced back, and the long-sequence accurate monitoring of the oil spill source and distribution area is realized. |
