摘要
[目的]分析徐州市时空尺度下农业碳排放时空特征与脱钩效应,为江苏省徐州市及其周边资源型城市未来农业的绿色高质可持续发展以及农业经济的良性增长提供理论与数据参考。[方法]采用排放系数法测算2000—2020年时空尺度下徐州市农业碳排放总量、强度和结构,而后基于Tapio脱钩模型分析其与农业经济发展间的脱钩关系。[结果](1)徐州市农业碳排放变化趋势总体呈“快速上升—波动上升—快速下降”3阶段,从2000年的1.61×10^(6) t先增后减至2020年的1.69×10^(6) t,形象地表现为“M”形。对农业碳排放贡献率大小依次是耕地利用(46.44%)、作物种植(31.90%)和牲畜养殖(21.66%),化肥是最主要碳源。(2)徐州市各区(县、市)农业碳排放量差异明显,经历了由升到降的长期演化进程,空间层面上总体呈现出“中部高,周边低”的分布格局,邳州市最为突出;(3)徐州市农业碳排放与农业经济发展总体经历了“弱脱钩—强负脱钩—扩张负脱钩—强脱钩”的变化历程,且“十三五”以来主要表现为强脱钩。[结论]徐州市农业碳排放随着低碳减排理念的不断深入而日趋合理,农业经济发展也取得了一定成效。
[Objective]The spatial-temporal characteristics and decoupling effects of agricultural carbon emissions at Xuzhou City,Jiangsu Province were analyzed in order to provide a theoretical basis and data reference for green,high-quality sustainable development of agriculture and the benign growth of the agricultural economy in Xuzhou City,and its surrounding resource-based cities in the future.[Methods]The total amount,intensity,and structure of agricultural carbon emissions at Xuzhou City from^(2)000 to 2020 were measured using the emission coefficient method,and their decoupling relationship with agricultural economic development was determine based on the Tapio decoupling model.[Results]①The overall trend of agricultural carbon emissions at Xuzhou City could be described as M-shaped(rapid rise-fluctuating rise-rapid decline)from 1.61×10^(6) t in 2000 to 1.69×10^(6) t in 2020.The contributions of factors affecting agricultural carbon emissions followed the order of arable land use(46.44%),crop cultivation(31.90%)and livestock breeding(21.66%),with chemical fertilizers being the most important carbon source;②Agricultural carbon emission at Xuzhou City varied significantly among districts(counties and cities)and had undergone a long-term evolutionary process from rising to falling,with a spatial distribution pattern of“higher in the middle and lower in the surrounding areas”,with Pizhou City being the most prominent;③Xuzhou City’s agricultural carbon emissions and agricultural economic development have generally undergone a process of“weak decoupling—strong negative decoupling—expansion of negative decoupling—strong decoupling”,and has mainly manifested as strong decoupling since the 13th Five-Year Plan.[Conclusion]Xuzhou City’s agricultural carbon emissions are becoming more and more reasonable as the concept of low-carbon emission reduction continues to deepen.Agricultural economic development has also achieved clear and convincing effects.
