摘要
【目的】通过分析河南省农业碳排放总量、强度及脱钩效应,为河南省农业高质量发展和制定减排政策提供参考。【方法】以河南省为研究对象,以广义农业为研究视角,运用碳排放系数法、强度计算公式、Tapio脱钩模型分别测算河南省2011—2020年的农业碳排放总量、强度与脱钩弹性系数,并进行相应的时空特征分析。【结果】河南省农业碳排放的碳源主要由CH4、N2O与化肥构成,就河南省农业碳排放总量而言,时序上可分为稳步增长期、快速下降期与波动性趋势下降期3个阶段,空间上可分为“高-稳步”“高-波动”“中-稳步”“中-波动”“低-稳步”“低-波动”6类区域;就河南省农业碳排放强度而言,时序上可分为加速下降期、波动下降期2个阶段,空间上可分为收敛下降型、加速下降型、后端上升型3类区域;就农业碳排放的脱钩效应而言,时序上可分为弱脱钩、强脱钩和反复转换3个阶段,空间可分为经济发展与生态环境关系向好区域、经济发展与生态环境关系稳定区域、经济发展与生态环境关系向差区域3种类型。【结论】河南省农业碳减排取得了突出成就,农业发展与生态环境的关系逐渐改善,但是缺乏稳固性;河南省畜禽业碳排放特征与其农业碳排放特征具有强相关性,农业碳排放总量、强度及脱钩效应存在地区差异性。因此,提出了要丰富畜禽业碳减排政策体系、制定具有区域针对性的农业碳减排政策、制度改革与技术创新双足并进的建议。
【Objective】Analyze the total amount,intensity and decoupling effect of agricultural carbon emissions in Henan Province,to provide references for the high-quality development of agriculture and formulation of emission reduction policies in Henan Province.【Methods】Taking Henan Province as the research object and generalized agriculture as the research perspective,the carbon emission coefficient method,intensity calculation formula and Tapio decoupling model were used to calculate the total agricultural carbon emissions,intensity and decoupling elasticity coefficient of Henan Province from 2011 to 2020,and the corresponding temporal-spatial characteristics were analyzed.【Results】The primary sources of agricultural carbon emissions in Henan Province were mainly consists of CH4,N2O and chemical fertilizer.The total agricultural carbon emissions in Henan Province can be divided into three temporal stages:steady growth period,rapid decline period,and volatility trend decline period and six types of spatial regions:“high-steady”“high-volatility”“medium-steady”“medium-volatility”“low-steady”and“low-volatility”.The agricultural carbon emission intensity in Henan Province,can be divided into two temporal stages:accelerated decline period and fluctuating decline period,as well as three types of spatial regions:convergent decline type,accelerated decline type and back-end rise type.The decoupling effect of agricultural carbon emissions can be classified into three temporal stages:weak decoupling,strong decoupling,and repeated conversion,and three spatial types:economic development and ecological environment good relationship region,stable relationship region and poor relationship region.【Conclusion】Henan Province has made outstanding achievements in agricultural emission reductions.The relationship between agricultural development and ecological environment gradually improved,but lacking stability.The carbon emission characteristics of livestock and poultry industry was strong correlated with agricultural carbon emission characteristics in Henan Province.And there were regional differences in the total amount,intensity and decoupling effect of agricultural carbon emissions.Based on the above analysis,following suggestions were proposed:enriching the carbon emission reduction policy system of livestock and poultry industry,formulating regionally targeted agricultural carbon emission reduction policies,and institutional reform and technological innovation going hand in hand.
