Zhejiang University (ZJU), China, Currently, research in ZJU mainly focuses on the N biogeochemical cycle in coupled human and natural systems (CHANS). We have built the nitrogen cycling model in the CHANS to include both natural and anthropogenic factors that drive the global and regional nitrogen cycles. Based on the CHANS model, we have analyzed the entire nitrogen cycling in China for 14 subsystems, and closed the N budget and their future trends in China. ZJU will contribute to INMS on the industrial N cycling on regional and global scales, source appointment of atmospheric and hydrospheric nitrogen pollutions, nitrogen footprint by CHANS mass balance approach and cost-benefit analysis.
