摘　　要：对金华市不同功能区的59个表层土壤土样磁化率和重金属含量的相关关系进行了比较。结果表明,(1)居住区、文教区、商业区、果园和荒地的磁化率与重金属之间的相关性不显著;(2)重金属污染严重的功能区磁化率与重金属的相关性较为显著。以城市的工业区、绿化区和菜园最为典型,工业区土壤磁化率与Cu、Pb呈正相关关系,农业区(菜园)土壤磁化率与Cr、Ni含量成显著的负相关关系,绿化区土壤磁化率与Pb、Cr、Ni的含量成显著的负相关关系;(3)不同土地利用方式的表层土壤磁化率和重金属含量的相关方向与强度不同,揭示各个功能区土壤磁化率和重金属的相关性关系,有利于特定功能区的重金属含量指示。The correlativity between magnetic susceptibility and heavy metal content of the surface soil sample of 59 in different functional zone were reserehed. The statistics show that ： （ 1 ） The relativity between magnetic susceptibility and heavy metal is not obvious in the areas of living, education, business, orchard and wasteland. （2） The relativity is obvious in the highly heavy metal polluted functional zone, including the areas of industry, greening and vegetable farm in the city. In the industrial zone, soil magnetic susceptibility has the positive relation with Cu and Pb. In vegetable farm, soil magnetic susceptibility has the negative relation with Cr and Ni. In greening zone, soil magnetic susceptibility has the obvious negative relation with Pb, Cr and Ni. （3） The kind and degree of relation between surface soil magnetic susceptibility and heavy metal content is depend on the way people use the soil. We can indicate the heavy metal content of the special zones easily and scientifically by revealing the relativity between magnetic susceptibility and heavy metal in each functional zone.
