- Abstract
Slope cropland and terrace are common land use types in Danjiangkou reservoir catchment areas and indoor artificial rainfall simulation methods are employed to study nutrients’ loss law of the two soils under different rainfall intensities, for the layout of soil conservation measures in farmland and the improvement of farming practices. The results are as follows: the pollutants TN, TP and COD in the two kind soils are wavy variation with rainfall time, the greater the rainfall intensity, the more loss of TP and COD, but some exceptions for TN, the accumulation concentration reaches the largest when the rainfall intensity is at 2.5 mm/min, second of 3.0 mm/min and the least of 0.5 mm/min.
