摘  要:
农业面源污染中的氮、磷排放是造成水体富营养化的最主要原因之一。笔者介绍了近年来国内外在氮、磷流失方面的研究进展,分别从淋溶及径流流失角度阐明了农业面源污染中氮、磷元素的流失机制。最后,探讨了目前土壤氮、磷流失及其途径的研究中存在的问题和研究方向,以期为改进施肥方式及研发农田氮、磷流失的控制技术提供借鉴。

摘  要:
Nitrogen and phosphorus emission of the agricultural non-point source pollution is one of the most important reason to cause eutrophication. This article describes the progress in the study of nitrogen and phosphorus loss recent years,and clarifies the mechanism of the loss of nitrogen and phosphorus in agricultural non-point source pollution from leaching and runoff losses. Finally,this paper investigates the problems and directions of the research of soil nitrogen,phosphorus and its loss pathways,in order to provide a reference for improving fertilization methods and researching technology to control loss of farmland nitrogen and phosphorus.
