| 摘 要： | The continuous increase of nitrate (NO3–) level in rivers is a hot issue in the world.However,the driving mechanism of high NO3–level in large rivers is still lacking,which has limited the use of river water and increased the cost of water treatment.In this study,multiple isotopes and source resolution models are applied to identify the driving mechanism of high NO3–level and key processes of nitrogen cycling in the lower reaches ...
