Abstract

This study investigated the effects of ryegrass and alfalfa at various growth stages on reducing runoff and sediments in soil boxes under simulated rainfall conditions. Growth stages were set as : early stage (late May), middle stage (late June), and late stage (late July). Four indices were used to assess the capacity of reducing runoff and sediments in terms of runoff reduction benefit (RRB), sediment reduction benefit (SRB), ratio between runoff and sediment reduction (RRSR), and soil average/stable infiltration rate. Effects of artificial grass and crops on runoff and sediment yielding were probed. It is highlighted that ryegrass performed best in reducing soil and water loss among treatments, and that the capacity of regulating runoff and sediments changed with growth stages. Since the majority of heavy rainstorms fall in the late growth stage (July–September) on the Loess Plateau, the functioning of artificial grass in reducing slope runoff and sediments should be stressed and investigated in further details
