摘要

N2O是最突出的温室气体之一，N2O排放的增加不仅会引发全球变暖，还会导致大气NOx水平过高和各种空气污染。国内外对N2O排放与资源利用关系的研究较少。基于排放源和数据可得性，构建了广东省能源利用N2O排放核算模型，并探讨了适用于行业减排的政策。我们发现，疫情导致的工业和交通活动减少导致N2O排放量显著减少，城市经济发展带来的垃圾燃烧是排放增长的重要来源，能源利用是2019 - 2021年N2O排放量的最大贡献者，由于社会恐慌导致的劳动力减少和社区严格执行遏制政策，N2O排放量明显下降。我们的模型强调了2020年新冠肺炎确诊病例与发电偏差率之间的负相关关系，强调新冠肺炎导致的劳动力减少是发电量减少的重要因素，这可能是固定源燃烧N2O排放量下降的重要诱因。

Integrated modeling and quantitative analysis of N2O emission before and after COVID-19: A case in Guangdong Province

N₂O is one of the most prominent greenhouse gases, and the increase in N₂O emissions not only triggers global warming, but also leads to excessive atmospheric NO_x levels and various air pollution. Research on the relationship between N₂O emissions and resource utilization is scarce worldwide. We constructed an N₂O emission accounting model for energy utilization based on emission sources and data availability in Guangdong Province, and explored the policies applicable to the sectoral emission reduction. We found that the pandemic-induced reduction in industrial and transportation activities resulted in a significant reduction of N₂O emissions, waste combustion brought about by urban economic development is an important source of emission growth, energy utilization is the largest contributor to N₂O emissions from 2019 to 2021, which has significantly dropped due to the reduction of labor force caused by social panic and the strict implementation of containment policies by the community. Our model highlighted a negative correlation between confirmed COVID-19 cases in 2020 and power generation deviation rates, emphasizing that the reduction of labor force caused by COVID-19 is a momentous factor for the decrease of power generation, which may be a prominence incentive for the fall of N₂O emissions from fixed source combustion.
