摘要
我国农业面源污染问题严重,氮肥是引起农业面源污染的主要因素之一。目前,国内外针对氮肥利用率低、土壤流失、淋湿严重等问题进行了大量的研究,现针对土壤培肥过程中氮肥引起的面源污染问题进行了梳理分析,针对氮素面源污染问题的重点研究内容及治理控制措施进行了总结,同时对今后氮肥面源污染防治工作提出了建议。
Agricultural non-point source pollution is serious in China.The nitrogen fertilizer has been one of the main factors to the agricultural non-point pollution.There are many studies focusing on the low nitrogen use efficiency,soil nitrogen loss and eluviations both at home and abroad.This paper conducted a literature review on non-point pollution problems caused by the nitrogen in the process of soil fertility.In this review,the key research contents and the controlling measures of nitrogen non-point pollution problems were summarized and for the future of nitrogen non-point pollution prevention and control work were put forward.
