Agricultural greenhouse gas accounts for a large proportion of global anthropogenic greenhouse gas emission.The paper carried on a calculation on greenhouse gas emission of China agricultural greenhouse gas emission,and analyzed influencing factors of agriculture greenhouse gas emission which has important significance for the development of Chinese and global low carbon agriculture.This paper calculated the emission of CH_4,N_2O and CO_2 in China from the year of 1993 to 2011,and analyzed the influence factors.The results showed that CH_4 emission was basically stable,which maintained at 2000 tons.Animal husbandry CH_4 emission was the largest contributor of agricultural source CH_4 emission.Taking the year of 2011 as an example,which accounted for 53.08%;N_2O emission was increased from93.21 tons of 1993 to 120.51 million tons of 2011,and the average annual growth rate was 1.63%.Planting was the main contributor to N_2O emission.Taking the year of 2011 as an example,which accounted for 54.36%of the total emission,land N_2O emission was the most,and the rice field was followed;agricultural source CO_2 emission increased from 15626.98 to 31258.10 million tons,and the average annual growth rate was 5.56%;fertilizer source was the largest source of carbon,in 2011,for example,fertilizer source of CO_2 emission was 18731.83 million tons accounted for 59.93%of the agricultural source CO_2emission.CH_4 and N_2O emissions of China Agriculture were mainly caused by animal husbandry and chemical fertilizers.And pesticides were major contributors to CO_2 emission of agriculture.At the end of this paper,based on the results of correlation analysis,the paper proposed countermeasures and suggestions for China’s low carbon agriculture,and demonstrated the significance of global low carbon agriculture development.
