It has great significance for controlling the influence of oil spill to get pollution oil slick information promptly.Due to its all day-night and all-weather capability,space-borne synthetic aperture radar (SAR) has been proven to be a useful tool for ocean oil spill monitoring.Taking an oil pollution accident occurred in Bohai Sea as study case,this paper puts emphasis on studying radar backscatter feature and the evolution of pollution oil slicks.The potential oil spill source area was deduced by analyzing the change of backscatter values of slicks.The obtained oil spill information was integrated with continuous wind field data to study the evolution of the slicks and its size change during the period.The results show that the corresponding methods should be applied in the different evolution phases for the different SAR image feature of oil slicks.It is possible to monitor and predict the movement of the slicks with consecutive radar imagery combining with additional information. 

Key words: Pollution oil slick    SAR detection    Backscatter feature    Evolution
