2016-2022年江苏省人为源NH3和NOx排放特征研究
Characterization of NH3 and NOx Emissions from Anthropogenic Sources in Jiangsu Province from 2016 to 2022
摘要
Abstract
To investigate the emissions of gaseous reactive nitrogen from anthropogenic sources in Jiangsu Province,an emission inventory of NH3 and NOx during 2016-2022 was developed using the emission factor method based on activity data from various emission sectors.The interannual variation trends and source characteristics of NH3 and NOx emissions were analyzed,and their spatial distribution in terms of total emissions and emission intensity was examined using ArcGIS.Results show that NH3 emissions first declined from 355.95 Gg in 2016 to 288.07 Gg in 2019,then increased to 303.79 Gg in 2022.Agricultural activities like livestock breeding and nitrogen fertilizer application were the key drivers of NH3 emissions,while NOx emissions exhibited a general downward trend,primarily influenced by energy,industrial and trans-portation sectors,with the highest and lowest values recorded in 2016(1 130.40 Gg)and 2021(858.45 Gg),respec-tively.The emission intensities of NH3 and NOx exhibited significant regional differences,with higher NH3 emission inten-sities predominantly concentrated in northern Jiangsu Province characterized by intensive agricultural activities,while NOx emissions primarily clustered in the industrialized southern Jiangsu region.关键词
