摘  要：
以十堰市畜牧业生产全过程中碳源和碳汇为研究对象,在参考国内外相关文献资料的基础上,对十堰市畜牧业生产全生命周期开展分析研究,选择直接生产和辅助生产作为系统边界,确定畜牧生产全过程CO2、CH4和N2O共3种主要温室气体的排放源,利用IPCC清单估算法和LCA模型对2011-2021年十堰市畜牧业生产碳排量、碳库量进行测算.结果显示,2011-2021年十堰市畜牧业全生命周期每年碳排放总量为11.24万~19.84万t,草地碳库总量为83.86万~148.93万t,全生命周期每年碳净排放总量为-132.48万~-64.08万t.另外,对实现畜牧业低碳发展的技术路径和生态策略进行了研究,以期为更好地推动十堰市畜牧业低碳化和生态化发展,更好地实施节能减排和畜禽养殖废弃物资源化利用提供依据.

摘  要：
Taking the carbon source and carbon sink in the whole process of animal husbandry production in Shiyan City as the re-search object,and based on reference to relevant domestic and foreign literature,analysis and research on the whole life cycle of ani-mal husbandry production in Shiyan City were conducted.Direct production and auxiliary production were selected as the system boundaries to determine the emission sources of the three main greenhouse gases(CO2,CH4and N2O)in the whole process of livestock production,and the carbon emissions and carbon pools of animal husbandry production in Shiyan City from 2011 to 2021 were mea-sured using IPCC inventory estimation method and the LCA model.The results showed that from 2011 to 2021,the total annual carbon emissions during the entire life cycle of animal husbandry in Shiyan City were 112 400 to 198 400 tons,the total grassland carbon pool was 838 600 to 1 489 300 tons,and the total annual net carbon emissions during the entire life cycle were-1 324 800 to-640 800 tons.In addition,the research on the technological path and ecological strategies for achieving low-carbon development of animal hus-bandry in Shiyan City was conducted,with the aim of providing a basis for better promoting low-carbon and ecological development of animal husbandry,and implementing energy conservation,emission reduction,and resource utilization of livestock and poultry waste.
