- Abstract:

Based on six kinds of factors of agricultural production, the total agricultural carbon emissions were calculated in He’nan Province during the period from 1993 to 2014. The results indicate that the amount of agricultural carbon emission showed a gradual upward trend in 22 years, which increased from 4.951 2 million tons in 1993 to 17.041 3 million tons in 2014, the average annual growth rate was 6.12%, in general, it can be divided into four periods: rapid growth period, slow growth period, rapid growth period, and slow growth period. The intensity of carbon emission increased from 720.60 kg/hm2 in 1993 to 2080.23 kg/hm2 in 2014, the average annual growth rate was 5.28%. The relationship between agricultural carbon emission and economic development presented typical inverted ‘U’ type curve, and the inflection point had appeared, but it was not obvious. The structure of agricultural carbon emissions changed with time, the average proportion rural electricity was the largest carbon source, followed by chemical fertilizer, agricultural plastic film, agricultural pesticide, agricultural diesel oil and plowing. Meanwhile, we calculated the decoupling elasticity using Tapio decoupling model, indicating that Henan’s carbon emissions and economic development of agricultural presented a variety of decoupling elasticities before 2004, including weak decoupling, expansion of negative decoupling, expansion connection and strong negative decoupling, leading to weak decoupling as the dominant state after 2004, accounting for 81.82%, which indicates that a certain of success has been achieved in reducing agricultural carbon emission in He’nan Province. Effective measures should be taken to achieve the decoupling between agricultural carbon emissions and economic development.
