Groundwater safety issues directly affect human health and quality of life. Sewage reuse is the main source of nitrate nitrogen pollution. The influencing factors of groundwater nitrate nitrogen must be analyzed to reduce the pollution risk of nitrate nitrogen. Based on the analysis of the literature, the influencing factors are comprehensively analyzed in the process of nitrate-nitrogen migration and transformation, and the influence of natural factors are discussed such as landform characteristics, soil type and soil structure on the migration of nitrate-nitrogen. The impact of human factors such as Nitrogen application, sewage irrigation, land use types and land planting ways are also analyzed, and the research results provide theoretical and scientific basis to support the remediation of groundwater nitrate nitrogen pollution, and can be used as reference.
