Abstract:
Using the background values of soil heavy metals in Guizhou Province as the standard values,the vertical distribution characteristics of heavy metal Cr in the soils from three kinds of the land types was analyzed,which was object to provide the scientific base for protect the soils in Caohai wetland ecosystems.The results showed that the soils in Caohai wetland had certain Cr pollution,and Cr content distribution was not uniform.Meanwhile,the Cr pollution in three kinds of soil types had a trend that the forest land was the highest,and the cultivated land was the lowest.However,the pollution were not significant in different soil profiles.And the Cr contents in the marshland and the forest land firstly increased the decreased in different soil profiles.Lastly,the Cr contents in the cultivated land were higher than other land types,which indicated that the arable activities from human-beings had significant effects on the accumulation of Cr in the soils.
