Abstract | Atmospheric reactive nitrogen (Nr) deposition has been modified significantly by human activities such as agriculture and fossil fuel combustion. Understanding the changes in Nr deposition is essential for maintaining the functionality and sustainability of ecosystems. Taking Beijing as a case study, we report long-term measurements of wet Nr deposition from 1999 to 2022 and dry Nr deposition from 2010 to 2022 and their relationship with China's air pollution control. Total Nr deposition to Beijing decreased by 34 % during 2010–2022, mainly caused by a decrease in dry N deposition by 54.27 %, from 47.86 kg N ha−1 yr−1 in 2010–2014 to 21.89 kg N ha−1 yr−1 in 2018–2022; reduced and oxidized N in dry deposition decreased by 29.93 % and 72.05 %, respectively. This was a result of the “Action Plan for Prevention and Control of Air Pollution (APCP)” and the implementation of the “Zero Growth in Fertilizer Use by 2020” in 2015. Our ground-based measurements provide evidence to support recent achievements in air pollution control and a reference and guidance for other regions of China and other countries for abating Nr pollution. |
