Application of a GIS-based revised FUSLE model in the Shangshe catchment

To support policy decisions, the greatest need is for models that can produce robust results using readily available data. The ER-USLE (Universal Soil Loss Equation with Effective Rain erosivity) model was developed from USLE with an effective rain erosivity factor (Re) instead of R (Rain erosivity) as well as increasing factor human being's single operation for cultivated land. The FUSLE model was developed from USLE for soil loss prediction in forest with a focus on the litter factor. Integrating the ER-USLE model and FUSLE for soil loss prediction in a catchment with various types of land use (cultivated land, forest, road etc) a revised RFUSLE model was developed for soil loss prediction in both cultivated land and forest. The RFUSLE model was tested in the Shangshe catchment by comparing its predictions with observed SSD at the river outlet in the year 2000, showing robust results. Results show that it is useful for prediction of annual soil loss for various types of land use in the Dabie Mountains, China. FUSLE model is available to many users and policy-makers in the Dabie Mountains, China.
