宿州市农业“三生”空间碳排放与脱钩效应

Carbon emissions and decoupling effects in Suzhou City′s agricultural"production-living-ecological"spaces

基于Tapio模型和碳排放系数法将宿州市2011—2022年农业碳排放划分为生产、生活、生态3个空间进行测算并分析其脱钩状态。研究表明:宿州市整体碳排放量呈现波动式增长,埇桥区碳排放量年均最高。宿州市“三生”空间中,生产空间碳排放量呈现缓慢增长,其中畜牧养殖碳排放最大;生活空间在2017年碳排放量超过生产空间且在不断增加,生活空间碳排放量主要以农村的食品消费和用电用水为主。碳排放与经济发展脱钩状态呈现“弱脱钩—扩张负脱钩—强脱钩”的变化,农业碳排放量环比增速在波动式下降,宿州市农业经济发展保持稳定增长。

Based on the Tapio model and the carbon emission coefficient method this study calculates and analyzes the agricultural carbon emissions in Suzhou City from 2011 to 2022 dividing them into three spatial categories production living and ecological spaces.The research shows that the overall carbon emissions in Suzhou City have exhibited fluctuating growth with the highest annual average emissions.In Suzhou′s"production-living-ecological"spaces carbon emissions from the production space have shown slow growth with livestock farming.In 2017 carbon emissions from the living space surpass those of the production space and have continued to increase primarily driven by rural food consumption and electricity and water usage.The decoupling state between carbon emissions and economic development has experienced a shift from weak decoupling to expansive negative decoupling to strong decoupling.The year-on-year growth rate of agricultural carbon emissions has shown a fluctuating decline while the agricultural economic development in Suzhou City has maintained steady growth.
