Rapid economic development and population growth have driven significant greenhouse gas (GHG) emissions from China's crop farming. Understanding specific features of these emissions is crucial for developing effective mitigation strategies. While existing studies primarily focused on accounting for GHG emissions at the entire crop farming system level, a critical gap exists in systematic measurements at individual crop level. This study addresses this gap by constructing a high-resolution China's provincial crop-specific embodied GHG emission inventory for years 2007, 2010, 2012, 2015, and 2017. The inventory quantifies embodied GHG emissions per unit yield and per unit area for 28 staple crops across 30 Chinese provinces, providing insights into status and structure of emissions across diverse crops and regions. The results demonstrate significant disparities in crop-specific embodied GHG emissions, with grain crops exhibiting higher emissions than cash crops-1.51 times greater per unit area and 0.86 times greater per unit yield on average. This dataset offers information for formulating effective emission mitigation strategies for crop farming in China.
快速的经济发展和人口增长推动了中国农作物种植产生大量温室气体排放。了解这些排放的具体特征对于制定有效的减排策略至关重要。虽然现有研究主要集中在核算整个农作物种植系统层面的温室气体排放,但在单个作物层面的系统测量方面存在关键差距。本研究通过构建2007年、2010年、2012年、2015年和2017年高分辨率的中国省级特定作物隐含温室气体排放清单来填补这一差距。该清单量化了中国30个省份28种主要作物的单位产量和单位面积隐含温室气体排放量,深入了解了不同作物和地区的排放状况及结构。结果表明,特定作物隐含温室气体排放存在显著差异,粮食作物的排放量高于经济作物,平均单位面积排放量高出1.51倍,单位产量排放量高出0.86倍。该数据集为制定中国农作物种植有效的减排策略提供了信息。
