Abstract:According to the latest revision of agriculture energy consuming data,this paper measured and calculated carbon emission of Chinese agriculture from 1980 to 2014,and used factor decomposition and decoupling effect analysis to analyze its variety.The consult shows that the sum of carbon emission of Chinese agriculture energy in sample period has totally maintained an increasing trend,which is 3325.68 million tons in total;the increasing in output value is the main force to push the rising of carbon emission in agriculture energy,though the decreasing of energy intensity controls the rising of carbon emission brought by output value,due to the energy construction dominated by coal,which hasn’t changed for a long period,the inhibitory effect is tend to be weakened in recent years.In the past 30 years,efforts made by agriculture department in saving energy and reducing carbon emission to reach the effect of decoupling didn’t act well,showing weak decoupling effect in total,and the gap to strong decoupling effect is bigger and bigger.To reach the goal of decoupling of agriculture energy carbon emission,we need to optimize our energy construction and lower the effect of carbon emission factor.
