Abstract: The research development of nitrogen and phosphorus transport and transformation at home and abroad are reviewed and summarized in this paper, the theoretic researches and modeling methodologies are studied on the basis of research achievement review in this field, the problems existing in the research are analyzed, and the research trends in the fields related are prospected. Through analyses of the main problems currently exiting in the fields related, the research directions are put forward: considering influences of multiple factors, integrating temporal-spatial variations and scaling effects, and combining theoretical research with modeling and experimental monitoring techniques, and widely applying key techniques such as “3S” techniques to improve theoretical and modeling research levels, effective control leaching losses of nitrogen and phosphorus from farmland, and to realize sustainable development of agriculture.
Key words: environment hydro-science; farmland; reviews; soil; nitrogen and phosphorus; transport; transformation
