| 摘 要： | 科学合理地进行农业生产是控制地下水硝态氮污染的关键。笔者综述了近年来国内外在地下水硝态氮污染方面的研究进展，提出水肥管理以及土壤质地结构是导致硝态氮淋溶的重要因素，总结了区域层面的调整氮肥和有机肥施用，合理耕作，水分管理以及新型高效缓控释肥料的施用等措施是预防土壤硝态氮淋溶，减少地下水硝态氮污染，提高氮素利用率的有效途径。介绍了物理观测法、离子示踪法以及模型模拟法在地下水硝态氮污染防治的重要意义，指出基于区域尺度的农田水肥管理措施和模型相结合是未来研究的热点。

| Abstract: | Nitrate leaching in farming soil is the main reason resulting in ground water pollution of nitrate.The author had summarized nitric nitrogen pollution in ground water in recent years,pointed out that fertilizer management and soil texture structure were major influencing factors.Also,some effective methods,such as fertilization based on nitrogen and organic fertilizers,rational cultivation,water management and new type efficiency fertilizer application,were put forward to reduce nitrogen leaching,reduce the... |
