This study aims to provide an accurate estimation of the interannual carbon footprint of the farm-land ecosystem in Zhangzhou.Utilizing data on farmland production input and crop yield in Zhangzhou from 2011 to 2020,the carbon footprint analysis method was applied to calculate carbon emissions,absorption,and overall carbon footprint of the farmland ecosystem.Findings indicate a fluctuating trend in total carbon emis-sions over the study period,initially increasing and then decreasing.The year 2015 recorded the highest total carbon absorption.Among grain crops,rice exhibited the highest carbon absorption,followed by sweet potato,soybean,potato,and miscellaneous grains,while vegetables,rapeseed,tobacco leaf,and sesame were the lead-ing non-grain crops in carbon absorption.Vegetables made the largest contribution to carbon absorption in Zhangzhou's farmland ecosystem.The carbon footprint was smallest in 2015 and largest in 2016,both of which were lower than the cultivated land area in the corresponding period,indicating a carbon ecological surplus.Rec-ommendations include enhancing fertilizer utilization efficiency through scientific and rational means and pro-moting low-carbon and environmentally friendly agricultural production techniques in Zhangzhou.
