With the normalization of extreme weather, the frequency of forest fires is increasing, and the burned land caused by fires has become the object of urgent attention for ecological restoration. Combining the methods of literature analysis, field investigation, and summary, the necessity of the occurrence and restoration of burned land under the background of extreme weather was discussed first, and the discussion context of “fire as an ecosystem damage factor” was clarified. Then, from the perspective of forest ecosystem, topography, fire impact, and disaster assessment, the cognition of forest fire land reflects the complexity of forest fire land ecological restoration, suggesting that it is necessary to properly formulate restoration strategies based on the land and disaster conditions. Finally, guided by the perspective of heterogeneity and sustainable development of the miraculous land, combined with the example of the miraculous land restoration after the Jinyun Mountain fire in the Beibei District of Chongqing in the summer of 2022, the ecological restoration process of “disaster assessment, clear goals,” “miraculous land formation, creating conditions”, “reconstruction of forest phase, optimization of forest stand,” “sound mechanism, the latter part of security” is introduced. The study is expected to provide a reference for the restoration and management strategy of forest fire land under extreme climates.
