摘要

This paper reports the results ofdata compilation on water erosion in Central Plateau of Morocco.It attempts to test the efficiency of the Revised Universal Soil Loss Equation (RUSLE) to predict erosion in Mediterranean forest settings. The experiment was conducted on two sets of 5 and 6 Wishmeier-type plots at the forest stations of Lalla Regraga and Ain Guernouch about 50 and 100km respectively from Rabat.The two experimental sites are characterized by a local semi-arid climate with moderate winters, granitic bedrockwith sandy soils,and a deciduous forest at the A(i)n Guernouch site and schistose bedrock with clayey soils, and a coniferous forest at the Lalla Regraga site. Analysis of data shows that effective erosion measurements varied from 50 to 840 kg/ha/yr, whereas estimated erosion by RUSLE was lower and varied from 10 to 200 kg/ha/yr.
