Spatial Distribution of Heavy Metals in Surface Soil of Zhejiang Pinghu
In this paper, the spatial structure of heavy metals were quantitatively described to soil in Zhejiang Pinghu City based on statistical methods, and the main factors of the spatial structure of heavy metals were discussed in the study region. The results showed that the soil experimental variogram model fitted better in the study area in the 7 heavy metals of As, Cr, Cd, Cu, Ni, Pb, and Zn. Principal component analysis reflected the elements Pb, Zn, Cu, As, Cr and Ni distribution in a same component; and elemental Hg and Cd each a separate component.
