Nitrogen Deposition Effects on Ecosystem Services and Interactions with other Pollutants and Climate Change

Improvement of stomatal resistance and photosynthesis mechanism of Noah-MP-WDDM (v1.42) in simulation of NO<sub>2</sub> dry deposition velocity in forests

“…It is unrealistic to consider such in-depth consideration in the land surface model at this stage, but we believe that the consideration of biological physiological processes needs to be continuously refined while the understanding of the land-atmosphere exchange process in the ecosystem grows. For example, the biogeochemical processes, such as under-canopy diffusion process of reactive nitrogen oxides, the emission of volatile organic compounds from low-canopy vegetation under nitrogen stress, the photochemical reaction through the canopy gap, the emission of soil nitrogen components, and the coupling process of carbon and nitrogen ratio (Weathers et al, 2001;Finnigan et al, 2009;Flechard et al, 2013;Dentener et al, 2014;Erisman et al, 2014;Makar et al, 2017;Moon et al, 2019;Guerrieri et al, 2020;Ke et al, 2020;Wang et al, 2021a), all have effects on the exchange of nitrogen oxides at the interface inside the canopy and are worthy of parameterisation research.…”

“…An increase in nitrogen deposition will cause an increase in litter and a decrease in soil decomposition, which will increase the carbon fixation of the soil (Stevens et al, 2004;Liang et al, 2020). Meanwhile, soil acidification caused by nitrogen deposition will reduce the number of microorganisms in the soil, reduce the production of methane, cause the degradation of peatland, and jointly affect the balance of greenhouse gases and the climate (Xu et al, 2009;Cui et al, 2010;Seinfeld and Pandis, 2012;Erisman et al, 2014). At present, studies have shown Published by Copernicus Publications on behalf of the European Geosciences Union.…”

Engineering microbial technologies for environmental sustainability: choices to make

“…In regions with high livestock intensity farming, e.g. in Flanders and the Netherlands, the emission of ammonia and the subsequent deposition in nearby natural ecosystems have become of critical concern because the deposition of reactive nitrogen, amongst others, decreases plant diversity (Erisman et al ., 2014). This has, for the first time in history, led to the implementation of unprecedented and harsh legislative restrictions on ammonia and nitrate emissions in agriculture by these regions.…”

At present, studies have shown that there has been a sharp rise in global and regional atmospheric nitrogen deposition, which exceeds the critical load of local ecosystems in many regions (Liu et al, 2013;Yu et al, 2019).…”
