Abstract：According to the research results of the farmland soil nitrogen transport and transformation mechanisms home and abroad currently,the damages of environmental pollution causing by soil nitrogen runoff loss have been recollected briefly,furthermore,influencing factors of soil nitrogen runoff loss have been deeply analyzed in the paper.Based on this,this paper puts forward some prevention measures,such as optimizing soil water and nitrogen fertilizer management,employing nitrogen fertilizer rationally,developing ecological agriculture,adjusting planting structure,extending slow controlled release nitrogen fertilizer and so on.Therefore,this paper has the great scientific value and guiding significance towards improving nitrogen fertilizer use efficiency,controlling farmland nitrogen runoff loss effectively,lightening contamination of nitrogen runoff loss to the environment,preventing and controlling the agricultural non-point source pollution,etc.
