Carbon balance of the tree layer in natural forests is affected by three carbon pools: tree growth, morta-lity, and recruitment. However, the dynamics of the sink of each carbon pool and the driving factors are still unclear. To this end, we used stepwise regression method and structural equation model to assess the effects of biotic (stand and diversity) and abiotic (soil, topography and climate) factors on three dynamic processes of carbon sinks, namely, stand growth, recruitment and mortality, in the natural forests of , based on the data from the seventh and eighth national continuous forest inventory of the Greater Khingan Mountains.

Article Synopsis
- The COFIX model was employed to simulate the impact of various factors such as rotation age, site index, and initial tree density on carbon flows in Maoer Mountain plantations, showing high reliability with minimal average errors in biomass and volume measurements.
- Under specific baseline conditions, it was found that extending rotation age and improving site index or initial density consistently increased total carbon stock and volume, indicating a positive correlation between these factors.
- The simulation revealed that during one rotation, about 271.57 tons of carbon could be captured per hectare, with significant transfers of carbon to soil and product carbon pools by the end of the rotation, highlighting the importance of effective management strategies in favorable site conditions.
