- Abstract:
-
Taking Xiaerxili area as the study area, we analyzed content characteristics and spatial distributions of five heavy metals (Co, Cr, Cu, Mn and Ni) of the soil samples. The single pollution index and the composite pollution index were used to assess the soil heavy metal pollution, and geostatistics method was applied to evaluate the spatial distributions characteristics of soil heavy metals in the study area. Results showed that contents of 5 kinds of heavy metals decreased in the order: Mn > Cr > Cu > Ni > Co in the research area, the heavy metals and organic matter belonged to the medium variability; the results of correlation analysis showed that the significant correlations were found between Co and Cu, Mn; the significant positive correlations were observed between Cr and Cu, Ni; organic matter and Cr, Mn, Cu, Ni had the positive correlation; spatial distribution characteristics of heavy metal contents as a whole showed the sequence: oasis area > desert area > mountain area; heavy metal pollution assessment results inicated that Co and Mn pollution was slight, Cr and Ni pollution was still clean but at the warning level.
