A filed study on soil nutrient loss of different slope landuse types in the Xiaolangdi Gorges Reservoir area was conducted under simulated rainfall.Results showed that available K and NO3-1 content were higher in surface runoff in slope cropland and intercrop land between crop and forestry than those in fallow land,intercrop land between forest and grass and afforestation land.Nutrient content in surface runoff and sediment was highest in the beginning of surface runoff,and then became stable.There was an enrichment of different forms of nutrients in sediment.The value of enrichment ratio was between 1.01 and 1.43,and there was no significant difference in the value of the six landuse types.
