坡耕地N、P流失是造成农业面源污染的重要原因.文章综述了国内外有关坡耕地N、P流失的过程特征,降雨、土壤、地形、耕作与管理因素对N、P流失的影响等方面工作的研究进展,探讨了不同控制措施,如覆盖、植物篱、保护性耕作、坡改梯等,控制N、P流失的控制机制、效果和可操作性;并进一步对坡耕地N、P流失的研究与控制方面等今后应加强研究的趋势进行了展望.

Nutrient loss from sloping farmland is an important factor for agricultural non-point source pollution (NPSP). This paper reviewed the loss characteristics of N and P from sloping farmland, the influences of rainfall, soil, terrain, tillage and management on N and P losses, explored the mechanisms, effects and feasibilities of different measures, such as coverage, plant-hedge, conservation tillage, slope to terrace, on the control of N and P losses, and prospected the research fields and tendencies which should be enhanced in the future.
