Abstract

Abstract: From a systematic perspective, the mechanism of economy, fertilizer and energy on agricultural carbon emissions were analyzed, a system dynamics model of agricultural carbon emissions in Henan Province was constructed, and agricultural carbon emissions under different policy situations were simulated. The results indicated that the agricultural carbon emissions in Henan Province showed a downward trend from 2020 to 2030, which was relatively slow. Changing chemical fertilizer structure and improving energy efficiency could inhibit agricultural carbon emissions. Finally, the theoretical suggestions for developing low-carbon agriculture in Henan Province were provided from the aspects of adjusting the level of public investment, reducing the proportion of nitrogen in fertilizer, and adjusting energy intensity.

Key words: agricultural carbon emissions, system dynamics, low carbon agriculture, Henan Province
