4.Scientific discoveries

Due to the broad existence of ridges, ditches and ponds in the rice cropping basin, the nitrogen cycle process is complicated, and the loading of non-point source nitrogen to waters is unclear. Therefore, we studied the coupling mechanism of nitrogen transformation and water quality, and built a model relating N lossing from cropland, N removal during transportation, and N loading to river. Analysis studies showed that the accuracy of the model was above 90%, correspondingly provided basis for accurate assessment and management of non-point pollution."
