Vegetation has important influences on water erosion,thus its effects on water and sediment re-duction have received great attention. The observed data for runoff and sediment yieldsfromfield runoff plotsbetween 2011 and 2014, the impacts of vegetation types, inter-month vegetation coverage variation, interannual vegetation growth and rainfall at different time scales(individual rainfall, monthly and yearly) onthe slope runoff and sediment yield were carefully investigated. The results showed that:(1) In co...
