By studying the pollution situation and distribution characteristics of "three nitrogen" in the shallow groundwater of Fuyang, the pollution sources and influencing factors are analyzed and revealed, indicating that the concentration of "three nitrogen" in the shallow groundwater in the study area tends to increase year by year in recent years, which is obviously affected by the seasons, and the concentration of "three nitrogen" decreases with the increase of sampling depth. Sewage discharge from chemical fertilizer plants, use and loss of nitrogencontaining organic fertilizers in agriculture, and animal manure are the main sources of nitrogen pollution in the area. In addition, hydrogeological factors such as the thickness, pH, DO and Fe~(2+) of the aerated zone influence the concentration and mutual transformation of "three nitrogen".
