摘　　要：以江西省泰和县境内的千烟洲试验站为研究对象,根据研究需要进行了实验区域的划定,对研究区域的地下水位、"三氮"、铁锰和pH值进行了长期的监测.结果表明:研究区地下水已经受到了农业氮面源污染的影响,总铁、可滤态锰、pH值、降雨和温度是地下水中"三氮"迁移转化的主要影响因子,相关性的强弱受到不同土地利用形式和影响因子范围的影响.This paper took the test station in Qianyan Zhou, Taihe County, Jiangxi Province as research object; first divided the experimental area according to the study needs, and then took a long time to monitor groundwater table, ammonia-nitrite-nitrates, ferrum-manganese and p H value of underground water in the research area. The results show that the groundwater in the study area has been affected by agricultural non-point nitrogenous pollution. Total iron, manganese in filtering state, p H value, rainfall and temperature are the main impact factors of the Ammonia-nitrite-nitrates transport and transformation in the groundwater, and the strength of the correlation is influenced by different land-use types and ranges of impact factors.
