Abstract Land use/cover changes affect both redistribution of 137Cs inventory and 137Cs depth distribution in soil profile. Redistribution of 137Cs inventory of several main types of land use/cover in Bashang region of Hebei province indicated that the region was in a wind erosion environment, where current agricultural land and deserted arable land are land use types suffering from the most serious wind erosion. 137Cs depth distribution denoted the conversion of soil erosion/deposition by wind in the process of land use/cover change, which proved the significance of vegetation restoration by afforesting or planting grass on the current agricultural land in stead of further cultivation for wind erosion control and eco-environmental improvement. The results suggested that the process of land use/cover change should be fully considered in estimating soil erosion/deposition rates using 137Cs as a tracer.
