China has committed to achieving peak CO2 emissions before 2030 and carbon neutrality 2060; therefore, accelerated efforts are needed better understand accounting in industry energy fields as well terrestrial ecosystems. The sink capacity of plantation forests contributes the mitigation climate change. Plantation throughout world intensively managed, there is an urgent need evaluate effects such management on long-term dynamics. We assessed cycling patterns ecosystems characterized by three typical species (Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.), oak (Cyclobalanopsis glauca (Thunb.) Oerst.), pine (Pinus massoniana Lamb.)) Lishui, southern China, using integrated biosphere simulator (IBIS) tuned with localized parameters. Then, we used state-and-transition simulation model (STSM) study active forest (AFM) storage combining disturbance history cycle regimes. 1) stock was lower at early age (<50 years) but higher advanced (>50 than that Chinese plantations. 2) densities plantations peaked 70 years (223.36 ​Mg·ha‒1) 64 (232.04 ​Mg·ha‒1), respectively, while density continued increasing (>100 years). 3) From 1989 2019, total pools followed upward trend (an annual increase 0.16–0.22 ​Tg ​C), largest proportional aboveground biomass pool. 4) AFM increased recovery after 1996 2009 plantations, did not result growth plantation. 5) proposed harvest planning reasonable conducive maximizing sequestration forest. This provides example a coupling potentially suitable for simulating China's supporting monitor reach neutrality.
