| 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. |
