英语真的好难啊想找个老师拜师~~谁帮忙翻译下
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.
