The pattern of soil nutrient loss from slope land was studied in Three Gorges Reservoir Area by means of simulated rainfall equipment.For purple soil and terra gialla soil,the nutrient content of surface soil of slope land declined and the declining extent of surface soil was increasing with rainfall intensities increasing,but the nutrient content of runoff and sediment was irrelative to rainfall intensities.The nutrient content of runoff was lower than that of sediment,but the discrepancy was mainly lied in the total nutrient and the discrepancy of the available nutrient was slight.For nutrient loss from slope land in Three Gorges Reservoir Area,the nutrient loss form purple soil was mainly caused by sediment,but that form terra gialla soil was caused by runoff and sediment.
