【摘要】 乡村振兴战略不断驱动各地区耕地利用转型升级,耕地利用转型的碳排放效应对发展绿色农业至关重要。利用熵值法模型和中国30个省(西藏和港澳台除外)2008—2016年面板数据测度各省耕地利用转型情况,并实证分析耕地利用转型对农业碳排放的影响。研究结果表明:近9年来中国耕地利用转型发展呈逐年增加趋势且地区差异明显。耕地利用转型对农业碳排放的影响效应具有显著地区差异。从全国来看,耕地利用转型能够有效降低农业碳排放且效果显著。从地区来看,中、西部地区耕地利用转型对农业碳排放的负向作用显著,而东部地区不显著。更多还原

【Abstract】 The strategy of rural revitalization continuously drives the transformation and upgrading of cultivated land use in various regions. The carbon emission effect of the transformation of cultivated land use was very important for the development of green agriculture. Entropy model and panel data of 30 provinces in China(except Tibet) from 2008 to 2016 were used to measure the transformation of cultivated land use in each province, and the impact of the transformation of cultivated land use on agricultural carbon emissions was empirically analyzed. The results showed that the transformation and development of cultivated land use in China had been increasing year by year with obvious regional differences in the past nine years. The impact of cultivated land use transformation on agricultural carbon emissions had significant regional differences. From a national perspective, the transformation of cultivated land could effectively reduce agricultural carbon emissions and the effect was remarkable. Regionally, the transformation of cultivated land use had a significant negative effect on agricultural carbon emissionsin the central and western regions, while in the eastern region, it was not significant.更多还原
