The universal soil loss equation is an empirical soil erosion model developed by scientists in the US for predicting average annual soil loss from slope croplan d or grassland It was modified and revised by many scientists through more th an 30 years based on the data collected from experimental plots and quantitative evaluation of factors causing soil loss and published as Agricultural Handbook No 282 in 1965 Afterwards, it was revised two times during 1970’s and 1990’ s respectively In 1997, it was published as Revised Universal Soil Loss Equat ion in Agricultural Handbook No 703 Since the model was developed, it has b een applied in soil conservation planing and national natural resources inventor yThe id eas and methodology of the model developing have been used as reference for sett ing up soil erosion models in other countriesThe USLE was introduced in Chin a from 1980’s and was modified and applied in different regions.
