Comparative analyses of agricultural carbon emissions at different agricultural economic development levels is helpful to understanding regional low carbon economic development. Based on the Environmental Kuznets Curve(EKC)hypothesis,using Yanchi County in the Ningxia Hui Autonomous Region and Pingdu City in Shandong as two comparative study areas,we analyzed the changing characteristics of agricultural carbon emissions,and the relationship between agricultural carbon emissions and economic growth in crop-livestock farming from 1995 to 2015 in order to provide a scientific basis for agricultural carbon reduction at different intensive levels. We found that the total agricultural carbon emissions for Pingdu were much greater than that of Yanchi.However,the annual average changing rates of agricultural carbon emissions and intensity in Yanchi increased,while that in Pingdu decreased. There were great differences in the causes of agricultural carbon emissions between two areas. Livestock farming in Yanchi County was a primary source of agricultural carbon emissions;while main carbon emissions in Pingdu included indirect carbon emissions from agrochemical materials and livestock farming. According to the agricultural carbon emission EKC hypothesis,we can conclude that agricultural carbon emission EKC for Yanchi was at the beginning of economic growth in crop-livestock farming. Therefore,Yanchi should weigh the benefits of economic growth and agricultural carbon reduction and try to develop an eco-environmentally friendly economy with recycling excretion from livestock farming,which not only prevent regional soil,air and water from being contaminated with excretion direct discharge,but also improve crop yield and reduce agricultural carbon emissions. However,the EKC for Pingdu was at a later period of economic growth in crop-livestock farming,indicating that it is possible to reduce carbon emissions and maintain certain agricultural economic benefits.Carbon emission reduction should be implemented strictly in Pingdu by using low-carbon environmental protection agrochemicals.
