Short Summary

This study examines the fine-scale spatiotemporal dynamics of biomass burning (BB) in China from 2016 to 2025 and finds a rebound in national BB activity after 2021.

Objective

• Investigate the recent fine-scale spatiotemporal dynamics of biomass burning (BB) in China and quantify the contributions of climatic, vegetation, and anthropogenic factors.

Study Configuration

• Spatial Scale: National scale with regional focus on northern agricultural and southern forested areas.
• Temporal Scale: 2016 to 2025, with a rebound in national BB activity after 2021.

Methodology and Data

• Models used: Optimized hourly active fire dataset.
• Data sources: Satellite remote sensing data (e.g., Himawari-8) and ground-based observations.

Main Results

• National BB activity showed substantial interannual variability, with an overall rebound after 2021.
• The rebound was concentrated in northern agricultural and southern forested areas, with pronounced daytime peaks.
• Interpretability analysis revealed land-use- and season-specific changes in variable importance.

Contributions

• This study provides new insights into the fine-scale spatiotemporal dynamics of biomass burning (BB) in China and highlights the need for region-specific and adaptive fire management strategies under increasing climate uncertainty.

Funding

• This research was funded by the Shandong Academician Workstation for Digital Intelligence in Ecology and Environment, Environment Research Institute, Shandong University.
