Abstract: 【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.
