Analysis on Temporal Change and Influence Factor of Agricultural Carbon Emissions in Baicheng City

Abstract

Based on the calculation model of agricultural carbon emissions, this study focused on the three aspects of agricultural material inputs, rice cultivation and livestock breeding to calculate agricultural carbon emissions, and analyzed their features of temporal changes. The influence factors of agricultural carbon emissions were studied based on STIRPAT model. The results indicated that the temporal change of agricultural carbon emissions in Baicheng City was divided into three phases: slow-growth phase, rapid-growth phase and fluctuation phase, and showed a continuous growth, agricultural carbon emissions intensity first went up and then down, with the maximum was 6.1921t/hm2 in 2008. Population, GDP per capita, agricultural machinery power, agricultural output ratio, rural investment, urbanization rate, net income of farmers per capita were the influence factors of agricultural carbon emissions, and their elasticity coefficients were 0.2605, 0.0874, 0.1126, -0.0766, 0.0353, 0.2083 and 0.1128, respectively.
