Modeling effects of changing deposition And forestry on nitrogen fluxes In a northern river basin

摘要

The application of a new, spatial nitrogen leaching/retention model N_EXRET to the Oulujoki river basin (22800 km~2) in Finland is discussed. The model Utilizes remote sensing-based land use and forest classification and evaluated export Coefficients obtained from detailed small catchment studies. The present and future N Depositions were estimated with the regional deposition model DAIQUIRI.
