Enzai Du is an associate professor at Faculty of Geographical Science, Beijing Normal University. His research interests focus on ecological processes in natural and urban forest ecosystems as well as their responses to multiple environmental changes, especially nitrogen deposition, climate change and air pollution. China has experienced rapid urbanization in past decades and provides us a unique research platform to understand the urban ecosystems and their ecological consequences. Enzai and his team thus extend their research scope to understand the large-scale patterns of urban soil properties and functional traits of woody plants in large cities across eastern China. They also aim to reveal how urban soils and plants respond to climate change, air pollution and anthropogenic disturbances, from biogeographical, biogeochemical and ecophysiological perspectives.
