Research on Characteristics and Effecting Factors of Crop Farming Carbon Emission in Henan Province, China

The greenhouse gas emissions from crops were carculated, and the LMDI model were used to analyze the influencing factors of carbon. The results indicate: The total carbon emissions of crops in Henan Province from 1991 to 2015 showed an overall upward trend, from 9.7651 million tons of CO2-eq in 1991...

Description
Summary:The greenhouse gas emissions from crops were carculated, and the LMDI model were used to analyze the influencing factors of carbon. The results indicate: The total carbon emissions of crops in Henan Province from 1991 to 2015 showed an overall upward trend, from 9.7651 million tons of CO2-eq in 1991 to 17.235 million tons of CO2-eq in 2015. The dominant position in greenhouse gas production in Henan Province is N2O for agricultural land, followed by rice field CH4. Compared with 1991, in 2015, the carbon emission intensity of unit GDP in Henan Province decreased by 59.52%, and the carbon emission intensity per unit of grain output decreased by 12.34%. LMDI analysis shows that the most important factors affecting the increase of carbon emissions in crop production in Henan Province are the agricultural economic level and industrial structure.
