| 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. |
