Abstract: The paper analyzed agricultural soil heavy metal content in Pucheng county, studied Mn, Sr, Pb, Zr and Zn content and their accumulation in 0-20 cm soil layer of 37 sampling sites, methods such as single factor pollution index method for evaluation of soil heavy metal pollution were used. The results showed that agricultural soil in Pucheng had certain Mn and Sr accumulation, but the difference among the sampling sites was not obvious, from the single factor pollution index, agricultural soil pollution in Pucheng was mainly Sr. Single factor pollution index of Sr was greater than 3, at the level of high pollution, that of Mn, Zn and Pb was less than 1, belonged to clean condition. Overall Sr content in Pucheng agricultural soil exceeded standard seriously, and restricted the development of agriculture and harmed human health, which should be timely dealt with; from the comprehensive pollution index, Mn, Pb, Zr and Zn content exceeded the standards, but was not serious and in the controllable range.
