Abstract

In this research, we analyzed parameters related to wind erosion (erodible fraction of soil, EF and dry aggregate stability, DASt) of different land use types including farmland, abandoned farmland and grassland in Bashang Area, Hebei Province, China. The relationships between the DASt or EF and soil physical-chemical properties for different land use types were also investigated. The results showed that the wind erodiblility (EF and DASt) of farmland is significantly different from that of grassland(P<0.05), and the differences of the wind erodiblility for grassland versus abandoned farmland and abandoned farmland versus farmland were not significant; The DASt and EF values of different land use types were ranked as grassland > abandoned farmland > farmland; The average particle sizes were ranked as farmland ≈ abandoned farmland > grassland; The contents of clay and silt fractions were ranked as grassland > abandoned farmland > farmland; The gravel contents were ranked as farmland>abandoned farmland>grassland; The soil organic matter and total nitrogen contents were ranked as grassland > abandoned farmland > farmland. There were significant correlations between the DASt or EF and the gravel contents or the average particle sizes, respectively; There was a significant negative correlation between the soil organic matter or total nitrogen contents and DASt on the natural grassland; There was a significant negative correlation between the EF and the soil organic matter or total nitrogen contents on the three land use. The results indicated that soil fertility of the grassland and the abandoned farmland was relatively better than farmland in Bashang Area, but the topsoil of the grassland and the abandoned farmland had higher wind erosion potential. Therefore, grassland reclaim should be prevented, and some farmlands undergoing wind erosion should be returned to forests or grassland. The vegetation coverage should be increased on the grassland to improve soil fertility and further to prevent wind erosion.
