气候变化是一个紧迫的全球问题,而农业部门是温室气体(GHG)排放的主要来源之一。为准确分析农业温室气体排放,构建了中国农业动态可计算一般均衡模型。我们的目的是研究中国农业温室气体排放和粮食生产的趋势和结构。结果表明:(1)中国农业CO2排放量将从2008年的47.77 MtC增加到2050年的239.99 MtC。农资投入是这一增长的主要来源。(ii)非CO2温室气体排放对农业温室气体的贡献最大,到2050年将达到2214.55 MtC。(iii)2008 - 2050年,中国农业温室气体排放总量将保持总体上升趋势,从2008年的2.2亿吨碳增加到2050年的2413.64亿吨碳,年均增长率为5.87%。(iv)到2050年,粮食生产的温室气体排放量将达到919.09 MtC。到2050年,单位粮食产量的温室气体排放量和单位面积的温室气体排放量将分别增加到343.81 kgC/t和4.46 tC/ha。研究结果对我国农业低碳发展具有政策启示,如提高农业物质利用效率、优化粪便管理与处理、推广有机种植技术等。
Climate change is an urgent global issue, and the agricultural sector is one of the main contributors to greenhouse gas (GHG) emissions. In order to accurately analyze agricultural GHG emissions, this study constructed a dynamic computable general equilibrium model of Chinese agriculture. We aimed to examine the trends and structure of agricultural GHG emissions, and grain production in China. Results show that (i) China's agricultural CO2emissions will increase from 47.77 MtC in 2008 to 239.99 MtC in 2050. The input of agricultural materials is the primary source for this rise. (ii) Non-CO2GHG emissions contribute the most to agricultural GHG, which will reach 2214.55 MtC in 2050. (iii) The total agricultural GHG emissions in China will maintain an overall upward trend from 2008 to 2050, increasing from 220 MtC in 2008–2413.64 MtC in 2050 with an average annual growth rate of 5.87%. (iv) GHG emissions from grain production will reach 919.09 MtC by the year 2050. GHG emissions per grain production and emissions per area will increase to 343.81 kgC/t, and 4.46 tC/ha by the year of 2050, respectively. These findings carry several policy implications to China's agriculture low-carbon development, such as improve the agricultural materials utilization efficiency, optimize manure management and treatment, and promote organic planting technology.
