| Abstract: | In modelling of sediment yields,the effects of time-variation of geomorphotgic and geologic factors on soil erosion were generally neglected. Errors of this neglection affect-ed the sediment yield models obviously. In this paper,a revised universal soil erosion e-quation was selected, the effects of errors of this neglection on it were tested by non-parametric hypothetical test method of Kolmogorov-Smirnov for a 22-year period within 21 catchments of the middle Huanghe River region,and the results show that the effects of errrors of this neglection on soil erosion were not significant,at 5% probability level. |
