【摘要】 [目的]对农户农业生产碳排放及影响因素进行研究,以便全面理性地认识农业碳排放的问题,促进农业低碳、可持续发展。[方法]选取湖北省武汉市黄陂、江夏区和鄂州市为研究区域,研究农户农业生产碳排放现状,测算农业生产碳排放,分析农业生产碳排放的结构特征,最后运用半对数回归模型分析碳排放强度的影响因素。[结果](1)在作物结构方面,种植水稻的碳排放总量最大,而莲藕的碳排放强度最大;(2)在碳排放来源方面,化肥是引起碳排放的主要原因,其次是人工投入;(3)在碳排放强度的影响因素方面,农户的年龄、务农年限、年均农业收入比例、耕地面积、土地质量、是否参加农业技术培训以及是否为村干部对农业生产碳排放强度具有显著的负向影响。[结论]农业低碳发展应重视科学技术,提升农业生产补贴,提倡适度规模种植,加强农户农地保护意识以及农业技术培训等。更多还原

【Abstract】 [Objective] Carbon emission and its influencing factors of farmers’ agricultural production was studied in order to comprehensively and rationally understand the issue of agricultural carbon emissions and promote the development of low-carbon and sustainable agricultural. [Methods] We selected Huangpi District, Jiangxia District, and Ezhou City of Wuhan City, Hubei Province as the research areas to investigate the status of farmer’s agricultural production carbon emissions, calculate carbon emissions from agricultural production, analyze the structural characteristics of carbon emissions from agricultural production, and finally analyze the influencing factors of carbon emissions intensity using the semi-logarithmic regression model. [Results](1)In terms of crop structure, the total carbon emission of rice cultivation was the largest, while the carbon emission intensity of lotus root was the largest.(2) In terms of carbon emission sources, chemical fertilizers were the main cause of carbon emissions, followed by input from human activities.(3) In terms of the influencing factors of carbon emission intensity, the age of farmers, the number of years of farming, the proportion of average annual agricultural income, the area of arable land, land quality, participation in agricultural technology training, and the village cadres showed significant negative impacts on the intensity of carbon emission from agricultural production. [Conclusion] Technological advancement should be emphasized to promote the low-carbon development of agriculture, agricultural production subsidies should be increased, moderate scale cultivation should be advocated, and farmers’ awareness of farmland protection and agricultural technology training should be strengthened.更多还原
