As one of the biological measures for soil and water conservation, hedgerows have been studied widely, but little information is available on their runoff and sediment process, thus it is necessary to study the benefits of runoff and sediment reduction in multiple hedgerows and to compare the benefits of different hedgerows configuration modes. The simulated rainfall experiment was conducted on three kinds of single plant modes, i.e., Hemerocallis citrine, Vetiveria zizanioides L., Paspalum natatum, and four kinds of combined modes, and a control plot, to compare the process of runoff and sediment-yield. three kinds of width of the single plant modes were set, respectively, which were 1, 2 and 3 lines, and the combination modes were 1 line of H. citrine and 2 lines of P. natatum, 1 line of V. zizanioides and 2 lines of P. natatum, 1 line of V. zizanioides and 2 lines of H. citrine, 1 line of P. natatum and 1 line of V. zizanioides. The results showed that all the different hedgerow modes improved soil physical and chemical properties and reduced water loss and soil erosion in different degrees. As for the same plant, the 2 line hedges achieved the better benefits of soil and water conservation. On the other hand, the benefits of runoff and sediment reduction of the combined modes were better than the single plant modes.
