摘　　要：通过对福州中心城区城市表层土壤重金属元素含量、磁学特征、色度参数的测试分析,探讨了土壤重金属元素富集变化与磁学特征及色度参数的相关性。结果表明,土壤亮度变化与Pb、Sr富集变化有着明显的负相关关系;而Fe元素富集变化对土壤红度、黄度参数变化有着显著影响,同时红度与铷(Rb)的变化以及黄度参数变化与Pb的富集都有着较好的相关性。土壤低频磁化率变化与Fe、Ni、Cu元素的富集变化有着很好的相关性,频率磁化率与土壤重金属元素富集变化并没有表现出明显相关性。The heavy metal concentrations, magnetic characteristic, chroma parameter were investigated of urban soil in Fuzhou, the correlation of the heavy metal concentrations in soil was analysed with the magnetic characteristics and chroma parameters. The results showed that there was a clear negative correlation between the brightness and content changes of Pb, Sr in soil. Content of Fe had a significant impact on redness and yellowness parameter of soil. While redness of soil had a good correlation with content changes of Rb, and yellowness of soil had a good correlation with content of Pb. Low-frequency magnetic susceptibility of soil had a good correlation with content changes of Fe, Ni, Cu. Frequency magnetic susceptibility did not show a significant correlation with the enrichment of soil hea＇cy metals.
