摘要

Soil loss is a serious environmental threat in many parts of Morocco. The degradation of fertile soils in mountain watershed influences agricultural productivity negatively. The revised universal soil loss equation (RUSLE) and geographic information system (GIS) techniques were adopted to quantify the annual rate of soil loss in the Tifnout Askaoun mountain watershed of 1488 km~2 in the south of Morocco. The spatial distribution of the annual rate of soil erosion was obtained by integrating geo-environmental variables into a GIS, including the erosivity of rainfall (R), the soil erodibility factor (K), the length and duration of soil erosion, slope inclination (LS), vegetation and management factor (C) and practice factor support (P). The result shows that the Tifnout Askaoun watershed has an average annual soil loss rate of 49.60 tonne/ha/year. The result obtained correlates with all the factors of the RUSLE equation. The maps produced in this study can be used as a database for future interventions to fight against erosion in the Tifnout Askaoun watershed.
