Soil loss tolerance should consider the conservation of the soil as a natural *** rates greater than loess deposition rate will cause soil depth ***,loess deposition rate must be determinable or predictable before they can be used as criteria for setting soil loss tolerance *** this study,radiocarbon dating was used to quantitatively study loess deposition rate in the Holocene in the loess Plateau in northern *** average loess deposition rate of LC,YC1,and HS profile at three locations（Luochuan,Yanchang,and Hengshan） was 0.0179 cm/a,0.0153 cm/a,and 0.0213 cm/a,***,a slope landform where LC2 profile located was reconstructed at about 12000 a *** using radiocarbon age of soil,loess deposition rate and paleoclimate which was determined with magnetic susceptibility of soil ***,loess deposition rate was applied on assessment of soil erosion risk in study area and Yan’gou ***,this study could provide theoretical basis for determination of soil loss tolerance and assessment of soil erosion risk,also a new method for quantificational research on landform reconstruction.
