Abstract
Based on the runoff plot data of Anjiagou watershed in 2007—2010,we research the rainfall-runoff per area and the cumulative sediment load under different vegetation measure conditions were obtained,and the characteristics of runoff and sediment under different conditions were analyzed.The results show that the chinese pine slope farmland had the highest runoff and the wheat slope farmland had the highest sediment load.The relationship of runoff yield in the five slope farmlands are in order of chinese pine slope farmlandwheat slope farmlandsainfoin slope farmlandbannedseabuckthorn slope farmland.The relationship of sediment yield are in order of wheat slope farmlandsainfoin slope farmlandchinese pine slope farmlandbannedseabuckthorn slope farmland.The rainfall-runoff and sediment load are positively correlated with slope.Sediment yield has some correlation with runoff.
