摘要:

ABSTRACTThis paper presents, in brief, the research into runoff and soil erosion presently being carried out in the Maphutseng area in Lesotho, Southern Africa. The research has a multilevel approach, i.e. it measures runoff and soil erosion at different scales in the same geographical area. A subcatchment, 5.4 ha in size, is sampled along with 12 runoff plots. The plots are located on three different soil types and have two different agricultural managements. Each trial has two replicas.The results, which are still preliminary, show that 10% of the rainfall ran off and that the soil loss was 16.4 t/ha from the subcatchment. The plots lost on average 0.65 t/ha and there was no significant difference between the two management types.
