Abstract：[Objective]Reducing soil respiration and enhancing carbon sequestration are key strategies for mitigating the adverse impacts of global warming.This study investigates the development of low-carbon agriculture in black soil regions,with a focus on identifying effective emission reduction drivers.[Method]The analysis is based on soil greenhouse gas emissions data from 2010 to 2020 in Daqing City,Heilongjiang Province,a representative black soil region in China.Using a combination of carbon footprint assessment,decoupling theory,and driving-factor decomposition,the study estimates carbon sequestration levels and identifies key factors that influence agricultural carbon emissions.[Result]①The overall carbon footprint in the study area exhibited a declining trend relative to total sown area,indicating positive ecological progress in farmland management.② Decoupling analysis revealed a predominant trend of weak decoupling,suggesting that agricultural output grew steadily while greenhouse gas emissions increased at a slow rate.This demonstrates the significant potential for low-carbon agricultural development.③ Improvement in agricultural production efficiency was identified as the most influential factor in reducing soil carbon emissions.[Conclusion]To further promote low-carbon agricultural development,Daqing should prioritize improvement in production efficiency,particularly through enhanced use of agricultural machinery and sustained investment in innovation and mechanization research.
