    Abstract:

    [Objective] Effects of different vegetation measures on red soil slope runoff were researched to provide a scientific basis for soil and water conservation and ecological restoration in the southern red soil region of China.[Methods] Monthly runoff and rainfall data from plots planted with Vetiver, Lespedeza, Neyraudia, Bahiasgrass during 2001 to 2010 were collected to analyze the above mentioned effects using statistical method. The plots were located at Changting County in Fujian Province.[Results] Vegetation measures could control slope runoff well, but due to the differences among vegetation structure, root and litter amount of the above measures, soil and water conservation benefits from the above measures were different. In the period of observation, the rank of annual runoff was:control plot with no vegetation measure >Bahiagrass >Neyraudia >Vetiver >Lespedeza. Water conservation benefit from Lespedeza measure performed best.[Conclusion] Vetiver, Lespedeza, Neyraudia, Bahiasgrass et al. vegetation could control slope runoff effectively and reduce soil erosion. Therefore, they can all be used as the excellent shrub/grass for soil and water conservation; and can be applied in the red soil region of Southern China, especially Lespedeza measure is recommended.
