About the Editors
Xuejun Liu is a full professor at China Agricultural University. He has been
engaged in studies on nitrogen (N) cycling, in particular on the N source, fate and
their impacts on soil acidification, eutrophication, and greenhouse gas emission in
major Chinese croplands. He has published more than 130 peer-reviewed SCI papers
in a number of international top journals, including Nature, Science and PNAS, with
H-index 36. He has established long-term cooperative relationship with Hohenheim
University (Germany), Rothamsted Research and Centre for Ecology & Hydrology
(UK), and Colorado State University and Stanford University (USA) as well as
Wageningen University & Research (NL) in his scientific career. He received
support from the China National Funds for Distinguished Young Scientists (2014)
and the national Ten-Thousand Talents Program (2016) and was chosen to be the
2016 Figure of the Scientific Chinese in Environmental Science and Light Industry.
His current research interests are atmospheric N deposition, PM 2.5 pollution, agricultural NH 3 mitigation, and their impacts on food security, ecosystem, and human
health.
Enzai Du is an associate professor at the Faculty of Geographical Science, Beijing
Normal University. His research interests focus on biogeochemical processes in
forest ecosystem and their responses to multiple global change factors, especially N
deposition, climate change, and air pollution. He has authored and coauthored about
40 peer-reviewed papers in international journals, many of which focus on the
pattern of atmospheric N deposition and its impacts on forest ecosystems. He also
serves as the coordinator of the IUFRO (International Union of Forest Research
Organizations) research unit (7.01.03) on atmospheric deposition, soils, and nutrient
cycles. He has co-chaired several sessions at IUFRO conferences and served as a
member of the international scientific advisory board of the 10
th International
Conference on Acid Deposition. Together with the IUFRO colleagues, he has also
coedited two special issues, including one on “Forest response to environmental
