| Abstract: | In this paper,the rainfall erosivity factor R and the relations of topographical factor LS in the loess region have been studied.This analytical results showed that the product EI30 of rainfall kinetic energy E and maximum 30-rain rainfall intensity I30 is a good-rainfall erosivity index which closely related with the soil loss on bare fallow land, hut it is better to select all individual rainfalls that greater than or equal to ten millimetres as the estimates of rainfall erosivity factors for a year or average annual.The relation of topographical factor LS can be used to estimate the effects of topographical factors in the loess region. |
