According to the 137Cs concentration distribution along a typical profile A-1, the sediment accumulation rate and the natural surface soil erosion rate are respectively 16.6t/km^2a and 45.95t/km^2a, which shows that about 63.88% of the eroded surface soil is removed by way of underground loss. The relative contribution ratio of surface soil loss and underground soil loss are respectively 70.13% and 29.87%. By comparison to the utmost soil formation rate 13.51t/km^2a in Maolan, the risk of soil erosion in the Engineering Monument grass-covered depression is higher.
