摘　　要：为探究牛养殖温室气体排放时空变化及技术进步和规模化养殖对其影响,结合生命周期评价法,测算31个省市区2000-2017年牛饲养温室气体排放CO_(2)当量,并利用LMDI模型分析技术进步、规模化养殖对牛温室气体减排的影响。结果表明:(1)从时间轴线看,全国牛养殖碳排放当量呈现“M”变化趋势,末期量高于基期值。(2)从空间分布看,区域差异较明显,存在明显高值和低值区域。(3)从影响因素看,技术进步和规模化生产对牛养殖温室气体排放量削减作用明显,规模扩张是排放量变化最主要原因。但经济规模、技术进步和结构效应地区差异化特征明显。通过养殖技术改进、规模养殖水平提升推动牛养殖实现温室气体减量、市场供给充足、产业发展增效等多重目标。To explore the temporal and spatial changes of greenhouse gas emissions from cattle breeding and the impact of technology and scale on them,combined with the life cycle assessment method,the CO_(2) equivalent of greenhouse gas emissions from cattle breeding in 31 provinces and cities in 2000-2017 was calculated.The LMDI model was used to analyze the impact of technology progress and scale breeding on greenhouse gas emission reduction of cattle.The results showed that:(1)from the perspective of time axis,the carbon emission equivalent of cattle breeding in China showed a trend of“M”,and the amount at the end of the period was higher than that at the base period(2)From the perspective of spatial distribution,regional differences were obvious,there were obvious high value and low value areas(3)From the perspective of influencing factors,technological progress and large-scale production had obvious effect on reducing greenhouse gas emissions from cattle breeding,and scale expansion was the main reason for the emission changes.However,there were obvious regional differences in economic scale,technological progress and structural effects.Through the improvement of breeding technology and the improvement of large-scale breeding level,we can promote cattle breeding to achieve the multiple goals of greenhouse gas reduction,sufficient market supply and industrial development efficiency.
