A method for identifying forest fire burn mark based on multi-source multi-temporal satellite remote sensing data comprises the following steps: selecting at least two different data source data, densely covering a monitoring area at certain intervals, and obtaining multiple multi-time spectral information analysis images; determining fire points through the spectral information analysis image, counting the number of the fire points, and using dots for identification in the spectral information analysis image. In the method, forest fire burn marks are identified through satellite remote sensing data, and data are collected through an unmanned aerial vehicle or through an ALOS high-resolution radar satellite and an SPOT high-resolution radar satellite. The obtained data is high in precision, the data obtaining modes are diversified, different use requirements are met, the fire point is determined by comparing the data of 15 minutes, the change of the normalized vegetation indexes of twotimes at any position is
