摘要：

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。

Abstract:

By analysing main factors affecting the migration and conversion of ammonia-nitrite-nitrates in groundwater, 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 divided. The groundwater table, ammonia-nitrite-nitrates, ferrum-manganese and pH value of groundwater in the research 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 suggest 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 impact factors of the transport and transformation of ammonia-nitrite-nitrates in the groundwater.

Key words: groundwater, pollution, conversion and transport of ammonia-nitrite-nitrates, impact factor, monitoring
