Abstract:
Studies on the transportation and flux of various kinds of heavy metals in runoff and sediment of five typical landuse types in West Tiaoxi catchment showed that the losses of Cu (0.21 mg.m-2.min-1), Zn (0.45 mg.m-2.min-1), and Pb (0.15 mg.m-2.min-1) in mulberry and that of Cr (0.06 mg.m-2.min-1) in paddy field were larger in surface runoff, while their losses in pinery were very small. Suspended thin particles played the main role on transporting heavy metals in surface runoff under all kinds of land uses. The losses from runoff were much lower than that from sediment, which only occupied 0.1%-4.9%, and the loss rate of Cu from runoff and sediment was higher than that of Cr, Pb and Zn.
