| 摘要: |
| 【目的】研究农业低碳化发展趋势及其驱动因素。【方法】基于农业碳排放，以黑土地区为研究区域，选取黑龙江省大庆市为研究对象，应用大庆市2010—2020年统计数据，采用碳足迹、脱钩理论、驱动因素进行联合分析，计算大庆市碳吸收与碳排放，揭示降低大庆市碳排放最有效的驱动因素。【结果】①相对于其播种面积而言，大庆市的碳足迹总体上呈下降的趋势，说明全市农田生态环境的发展较为乐观；②大庆市农业碳排放脱钩特征主要以弱脱钩为主，表明农业产值保持高速增长，发展态势良好，还有较大的低碳发展潜力；③提高农业生产效率是降低该市农业碳排放量的关键。【结论】因此，大庆市未来一段时间仍应关注农业生产效率，进一步推动农机使用效率、农业机械的创新与研发等。 |

| 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. |
