Based on the perspective of crop production,this paper calculate the carbon emission of various carbon sources in the utilization of cultivated land.The method is carbon emission coefficient proposed by the United Nations Intergovernmental International Panel on Climate Change,and the spatial distribution difference and temporal development characteristics of carbon emission in Anhui province are analyzed.Then the paper construct the TAPIO decoupling model,and from the emission reduction flexibility,energy saving elasticity,development flexibility,we analyse the degree of decoupling between the utilization of carbon emission and economic development in Anhui province.The findings are as follows::the carbon emission of the utilization of cultivated land resources in Anhui province shows an overall decline and decreases from north to south;On the whole,the carbon emission of cultivated land resources utilization in Anhui is generally weakly decoupled and the trend is increasing intensity from north to south.
