To provide decision-making references for ecological protection and high-quality development of the Yellow River Basin from an agricultural perspective, a carbon emission accounting list for agriculture in the Henan section of the Yellow River Basin was constructed based on carbon sources from crop planting and livestock breeding. The agricultural carbon emissions from 2012 to 2021 were calculated, and the spatio-temporal evolution characteristics of agricultural carbon emissions were analyzed using the statistical comprehensive analysis method and the natural break point method. The results show that: a) From 2012 to 2021, the total agricultural carbon emissions in the Henan section of the Yellow River Basin showed an overall downward trend. The period from 2012 to 2015 was a stage of “minor fluctuations and relative stability”, and the period from 2016 to 2021 was a stage of “obvious changes and fluctuating decline”. b) In the agricultural carbon emissions of the Henan section of the Yellow River Basin, the carbon emissions from agricultural materials accounted for a relatively large proportion, with an average annual proportion of 54.15%. Among them, fertilizers were the main source of carbon emissions from agricultural materials, with an average annual proportion of 50.17%. In the spatial dimension, Jiyuan, Hebi, Jiaozuo, and Sanmenxia had less cultivated land area and lower agricultural carbon emissions, Zhengzhou, Luoyang, and Puyang had significant achievements in agricultural carbon reduction, Kaifeng, Xinxiang, and Anyang still had relatively large agricultural carbon emissions.Based on this, the implementation path of agricultural carbon reduction was proposed, including compiling a carbon source list, establishing unified standards, conducting surveys and monitoring, strengthening surface source control, innovating circular utilization, and implementing unified management in Henan Section of the Yellow River Basin.
