Abstract: Forest fire is one of the most critical disturbance factors in forests, which damages ecosystem stability and exerts significant regulatory control over vegetation recovery, regeneration, and succession. Here, we summarized research progress on the effects of forest fires on vegetation restoration, regeneration, and species diversity, focusing on factors such as fire intensity, frequency, burnt wood management practices and recovery time. The intensity and frequency of fires, recovery periods, and different methods for managing burnt wood had shortor longterm impacts on vegetation recovery and species diversity, altering forest structure and function. Additionally, natural regeneration and artificial restoration can lead to distinct processes of vegetation recovery, renewal, and succession. Future research should focus on: (1) strengthening the long-term monitoring of post-fire vegetation restoration; (2) identifying the key driving factors in post-fire processes; (3) developing predictive models for vegetation regeneration trajectories. This study clarifies the effects of forest fires on vegetation recovery and species diversity, providing guidance for the restoration and management of forest ecosystems after fire.

Key words: fire disturbance, vegetation restoration, vegetation renewal, species diversity
