为研究地下水中“三氮”迁移转化的主要影响因子，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，通过数据整理、作图分析后，利用 SPSS 软件对“三氮”、总铁、可滤态锰和 pH 值的相关性进行分析。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；地下水中铁、锰具有显著的伴生性；铵态氮和亚硝酸盐态氮与铁、锰存在显著的正相关。总铁、可滤态锰、pH 值、温度和降雨是地下水中“三氮”迁移转化的主要影响因子。通过“三氮”迁移转化影响因子的分析，可为农业氮面源污染的防治提供一定的理论基础。

By analysing main factors affecting the migration and conversion of ammonia-nitrite-nitrates in groundwa-ter,we aim to provide theoretical basis for the prevention and control of agricultural non-point source nitrogenous pollution.Qianyanzhou test station in Jiangxi Province was selected as research object and experiment plots were di-vided.The groundwater table,ammonia-nitrite-nitrates,ferrum-manganese and pH value of groundwater in the re-search area were monitored in long term.Through data sorting,diagram analysis and SPSS software,we analysed the correlation among ammonia-nitrite-nitrates,total iron,manganese in filtering state and pH value.Results sug-gest that the groundwater in the study area has been affected by agricultural non-point nitrogenous pollution.Ferro-manganese in groundwater are apparently associated.Ammonium nitrogen and nitrite nitrogen are positively related with ferro-manganese.Total iron,manganese in filtering state,pH value,temperature and rainfall are the main im-pact factors of the transport and transformation of ammonia-nitrite-nitrates in the groundwater.
