摘要
以于桥水库流域为例，通过人工降雨──产流──Ｎ、Ｐ输出模拟实验，查清地形、坡度与Ｎ、Ｐ流失的关系，总结出带规律性的结论。
This paper, taking the Yuqiao Reservoir Area as an example,find out the relationship between topography and slope and nitrogen (N) and Phosphorus (P) losses by imitation of the processes of man-made rainfall, flow-making and N and P output,some conclusions are offered.
