Forest carbon sequestration processes are governed by complex interactions among multiple carbon pools. Elucidating the driving mechanisms of these processes is critical for optimizing carbon sequestration potential and mitigating global climate change. In this study, the authors systematically quantified the relative contributions of topographic, stand structural, soil physiochemical, and climatic factors to carbon sequestration across four functional pools: growth (GCS), recruitment (RCS), mortality (MCS), and total (TCS) carbon sequestration. Through stepwise regression analysis and structural equation modeling, they identified key determinants and their interactive effects on carbon sequestration processes based on 168 natural larch-birch mixed forests in northeast China that were collected from the seventh and eighth national forest resources inventories.
