Polluting Extent of Heavy Metal is Analyzed in Topsoil

Abstract:

Eight heavy metal elements（As、Cd、Cr、Cu、Hg、Ni、Pb、Zn）of five function areas are ploted in city by using matlab, according to their concentration and distributing extension. Overproof concentration of eight heavy metal elements is estimated by using aberrance coefficient. Cumulate exponent of overground is choosed to optimize model. Polluting extent of eight heavy metal elements is analyzed in quantity.We expatiate diffuse character of eight heavy metal elements in soil and moving law,when heavy metal elements enter soil.
