| 英文摘要 | Rice cultivation stands out as a major greenhouse gas source, emitting 10-20% of global CH4 emissions. How to accurately estimate CH4 emissions from paddy rice and their mitigation potential has been key concerns. Agroecosystem models have unique advantages in understanding CH4 processes, simulating CH4 emissions dynamics, optimizing management practices, and quantifying mitigation potentials. However, current agroecosystem models need to be substantially improved for these purposes. In this study, we develop a comprehensive agroecosystem model, MCWLA-Rice 2.0, to better depict the production, oxidation, and emission processes of CH4 and improve the simulation of root exudates, the effect of nitrate fertilizer on CH4 emissions, and the decomposition of external organic carbon. We calibrate and validate the model and demonstrate its performance in simulating the rice cultivation system under different fertilizer and irrigation treatments at seven sites across Asia. Elaborating on both aboveground and belowground carbon-nitrogen coupling processes, MCWLA-Rice 2.0 is a valuable tool for simulating rice productivity and CH4 emissions under various environments and managements, effectively supporting the development of climate-smart agriculture. |
