Climate change and human activities, including heat emission, nitrogen (N) emission and water management, are altering the hydrothermal condition and N transport in the soil and river systems, thereby affecting the global nitrogen cycle and water environment.


“We need to assess the impacts of these human activities on global river temperature and riverine N transport,” said Prof. Xie Zhenghui from the Institute of Atmospheric Physics of the Chinese Academy of Sciences. “Quantitative assessment can not only improve our understanding of the material and energy cycle that occur in response to anthropogenic disturbances, but also contribute to protecting river ecosystems.”

Xie and his collaborators from the Chinese Academy of Sciences incorporated the schemes of riverine dissolved inorganic nitrogen (DIN) transport, river water temperature, and human activity into a land surface model, and thus developed a land surface model CAS-LSM. They applied the model to explore the impacts
