| Abstract: | By the trace of 137Cs and soil granularity analysis,the relationship between land-use and soil wind erosion was investigated in Bashang of Hebei Province.The results indicate that the land use types with erosion intensity,from the higher to the lower,are sandy hilly grassland > cultivated land > grassland converted from cultivated land > artificial forest > gravel hill grassland.Hence,to recover the vegetation,the gravel hilly grassland in this region should be reserved and the original vegetation in it sho... |
