Abstract: A method of determining nitrous oxide emission of a river based on land-river-atmosphere simulation, includes the steps of: obtaining nitrogen emission from land in each region; dividing the nitrogen emission into a prediction set and a test set; using nitrogen emission prediction set, and geographical variables and climate variables under the nitrogen emission prediction set to process RF regression model training to obtain a trained RF regression model, using nitrogen emission test set, and geographical variables and climate variables under the nitrogen emission test set to process RF regression model training to obtain a trained RF regression model, and outputting a river water quality concentration of each sub-basin in each region; obtaining river hydrological parameters of each sub-basin, inputting the river hydrological parameters and river water quality concentration of each sub-basin to an air-water interface gas exchange model to obtain a total river N2O emission in each sub-basin.
