Abstract:

This study quantitatively assesses spatiotemporal distribution characteristics of agricultural carbon emissions,and their relationship with the agricultural economy,providing scientific support for achieving Chineses dual carbon goals. The carbon emission coefficient method was used to calculate carbon emissions,and ArcGIS software was applied to visualize the spatial distribution patterns of agricultural carbon emissions and their intensity. The Tapio decoupling model was employed to analyze the elastic relationship between agricultural carbon emissions and the agricultural economy,revealing their dynamic changes. The results incidated that from 2010 to 2021,agricultural carbon emissions in the southwestern region generally declined. Fertilizers,as the primary carbon emission source,accounted for an average of 68.65%. Spatially,carbon emissions exhibited a pattern of high values in the central region and low values in the eastern and western areas. Agricultural carbon emission intensity decreased from 1.02×104 t·yuan-1 in 2010 to 0.33×104 t·yuan-1 in 2021,a reduction of 67.65%,with spatial distribution characterized by high values in the southwest and low values in the northeast. Furthermore,the relationship between agricultural carbon emissions and the agricultural economy in the southwestern region shifted gradually from weak decoupling to strong decoupling. This indicates that while effectively controlling agricultural carbon emissions,the southwestern region maintained steady agricultural economic growth,achieving a positive interaction and coordinated development between emissions reduction and economic growth. These findings offer valuable insights for exploring low-carbon agricultural development models.

Key words: low-carbon agriculture, agricultural carbon emissions, carbon emission intensity, agricultural economy, Tapio decoupling model
