Understanding the nonlinear effects of some dominant drivers on forest carbon sink can underpin forest management and climate change mitigation, however remains unclear. By utilizing multi-source remote sensing data, statistics and machine learning approach, we identified the thresholds within the partial impacts of forest stand characteristics, fire disturbance level, afforestation/reforestation intensity and urbanization rate across China. Based on these thresholds, we proposed the optimal fire prevention and reforestation schemes across different regions. Moreover, we provided the optimal forest thinning and aging prevention strategies for every forestland in China. These managements can not only mitigate carbon sink saturation, but also promote timber production.
