The reduction in vegetation cover enhances splash impact, mechanical crust formation and surface sealing (Wilcox et al., 1988; Weltz et al., 1989; Bari et al.,
1993). Compaction also smoothes the soil surface (Nash et al., 2003, 2004). Low vegetative cover, low surface roughness and high bulk density lead to low infiltration capacity, and consequently the routes act as net contributors of water to their downslope areas. Using a standardized soil penetration test as a proxy for infiltration capacity, Stavi et al. (2008) obtained a mean penetration depth of approximately
6mmat trampling routes, compared to 10mmfor intershrub areas and 18 mm under the canopy of S.

植被覆盖的降低会产生巨大的影响,机构土层的形成以及表层的封闭(Wilcox et al., 1988; Weltz et al., 1989; Bari et al.,1993).踩压也会使土壤表层平滑(Nash et al., 2003, 2004).低植被覆盖,低表层糙土以及高块密度导致渗透力,而相应地这些践踏过的路线便成为下坡地段水的净成因.用标准化封渗透测试作为渗透力的代表,Stavi et al. (2008)得到的践踏路线渗透深度中值约为6mm,相应地,林间地则为10mm,而树荫下则为18 mm.
