摘　　要：地表径流和壤中流是降雨侵蚀条件下坡耕地土壤氮、磷迁移损失的重要途径与载体。当前,国内外关于坡耕地地表径流影响氮、磷流失的研究成果较多,而壤中流运动对氮、磷流失的影响研究还处于探索阶段。回顾了国内外在坡耕地养分流失领域开展的研究工作,重点阐述了地表径流和壤中流对坡耕地氮、磷流失影响方面取得的进展,并分析了其中存在的问题与不足,建议今后应加强地表径流和壤中流耦合对坡耕地氮、磷迁移规律影响的研究,为水土保持生态建设和农业面源污染防治提供基础数据。Surface runoff and subsurface flow are important ways and carriers of soil nitrogen and phosphorus transfe and loss of slope farmland under the conditions of rainfall erosion.At present,there are many study achievements on nitrogen and phosphorus loss of slope farmland affected by surface runoff at home and abroad,while the study on influence of subsurface flow movement to the loss of nitrogen and phosphorus is still in initial stage.The paper reviewed(he study on the domain of nutrient loss of slope farmland both at home and abroad,mainly elaborated the achieved progress of influence of surface runoff and subsurface flow to the nitrogen and phosphorus loss of slope farmland,analyzed the existing problems and insufficiency and suggested to strengthen the study on influence of the coupling of surface runoff and subsurface flow to the nitrogen and phosphorus transfer law of slope farmland in the future for providing basic data for soil and water conservation ecological building and prevention and control of agricultural area-source pollution.
