利用2004年-2014年酉阳县种植业生产投入、产出等数据,采用碳足迹模型方法,选定主要要素的排放系数和碳吸收率,分析农作物种植中碳吸收、排放的情况.结果表明:1酉阳县种植业的碳生态承载力未超负荷,固碳能力稳步上升,年平均增长率2.9%.2酉阳县种植业的固碳能力和单位碳足迹产值效益提升主要得益于作物种植结构调整,说明发展低碳农业符合社会经济发展的要求.3秸秆焚烧带来巨大碳排量以及不断增加的化学物质消耗,加剧了农业面源污染风险.
Based on the data of production inputs and outputs of planting industry in Youyang County from 2004 to 2014 and using the carbon footprint model method, the emission factors and carbon absorption rates of the main factors were selected to analyze the carbon absorption and emission during crop planting. : 1Youyang County planting industry carbon ecological carrying capacity is not overloaded, carbon sequestration capacity increased steadily, with an average annual growth rate of 2.9% .2Youyang County planting industry carbon sequestration capacity and unit carbon footprint value-added benefits mainly due to The restructuring of crop production shows that the development of low-carbon agriculture meets the requirements of socio-economic development.3 The enormous carbon emissions from straw burning and the rising consumption of chemical substances exacerbate the risks of agricultural non-point source pollution.
