Zusammenfassung:The embodiment of the invention discloses an ice lake area dynamic change monitoring method, device and equipment and a medium, and the method comprises the steps: generating an enhanced backscattering coefficient graph through employing a multi-scene dual-polarization SAR image, and determining a first average value graph and a first standard deviation graph corresponding to the enhanced backscattering coefficient; generating an interference coherence coefficient graph by using the multi-scene SAR image, and determining a second average value graph and a second standard deviation graph corresponding to the interference coherence coefficient; determining a target mask range of the to-be-analyzed glacial lake based on the first average value map, the first standard deviation map, the second average value map and the second standard deviation map; processing the enhanced backscattering coefficient diagrams of all monitoring periods by using an Otsu method in a target mask range to obtain a glacial lake area cha
