This paper studied the process of soil erosion and nutrientl oss including organicmatter

total N and available P in the sloping lands through the lab artific ial rainfall

a-nd the effects of slope gradient and rainfall intensity upon the lossing process. It also analysed the process of soil erosion and nutrient loss of two treatemnts in the bare sloping lands and the net covering sloping lands. The results indica ted that the amount of nutrient loss went up with an increase in slope gradients and rainfallintensity

and that after the kinetic energy of raindrop was eliminated by the covering net in the experimental plot

the amount of soil and nutrient loss was reduced by 60% or so as compared to that in the bare sloping lands. The amount of nutrient loss was in the correlation with soil loss. The available nutrients in most of sediment sampes were higher than those in the soil with available P in particular.
