Abstract: Based on the test results of magnetic parameters and chemical analysis of 84 surface and 17 section soil samples, 11 rock samples, the distribution of soil magnetic susceptibility and heavy metal elements, origin and their correlativity were studied in Huzhou City where industry and agriculture are flourishing. The study revealed that： The high anomalous areas of magnetic susceptibility are consistent with those of soil heavy metal elements in the surface soils in the Huzhou City of developed industry and agriculture areas; The magnetic susceptibility and heavy metal element contents in the section soils are both decreasing from the upper to the lower; The high anomaly of the magnetic susceptibility and heavy metal element contents in the surface soils resulted from the influence of mankind economic and engineering activities in Huzhou City, such as free piling up mucipal garbage, applying garbage as fertilizer, discharge of industrial waste gas, material and water, overapplication of pesticide and chemical fertilizer in the local towns; It is obvious that the correlativity between soil magnetic susceptibility and Cd、Hg、Pb、As and Cr contents are different in the different environmental conditions. In dry land magnetic susceptibility is highly correlated with Hg and Pb and has poor correlativity with Cd、As and Cr; in paddy field magnetic susceptibility is highly correlated with Pb and As, and evidently with Cd and no correlativity with Hg and Cr.
