In recent years, due to the influence of human activities and global warming, the coral reef ecosystem in the South China Sea (SCS) has degraded, and bleaching occurs. Utilizing the remote sensing method to monitor and understand the bleaching status of coral reefs is of great value to the protection and management of the ecological environment in the SCS. This study first obtains coral reef bleaching alert areas (BAAs) through multiperiod sea surface temperature data (SST) and selects the Antelope Reef in the Yongle Atoll of the Paracel Islands as the research area. Then, a new coral reef bleaching monitoring model is proposed, which uses water depth correction, coral reef classification, reflectance adjustment and threshold selection to carry out multitime series coral reef bleaching monitoring research with Landsat-8 remote sensing images from 2013 to 2018. The results show that the model can effectively obtain coral reef bleaching areas and provide a feasible approach for the monitoring of coral reef bleaching in the South China Sea.
