摘　　要：选取云南沧源和个旧两个矿区周边土壤,研究土壤磁化率与重金属之间的相关性。结果显示,沧源矿区周边土壤低频磁化率χlf只与有效态Cd含量呈显著正相关,而个旧矿区周边土壤低频磁化率χlf与总Pb含量呈显著正相关,与总Zn含量极显著正相关,与有效态Cd含量呈显著负相关;两个矿区土壤低频磁化率χlf与有机质、pH和电导率的相关性均未达到显著水平。本研究为矿区土壤磁化率和重金属的关系作了有益的探索。Farmland soil samples were collected around two mining areas in Cangyuan and Gejiu, Yunnan, and the correlations between soil magnetic susceptibility and heavy metals were investigated. The results showed that the lowfrequency magnetic susceptibility(χlf) of the soil around the Cangyuan mining area was only significantly positively correlated with the available Cd. The χlf around the Gejiu mining area was significantly positively correlated with the Pb content, and was extremely significantly positively correlated with the Zn content, while had a significant negative correlation with the content of available Cd. The correlation between χlf and organic matter, pH and electrical conductivity around the two mining areas was not significantly different. This study was helpful to explore the relationship between soil magnetic susceptibility and heavy metals in a mining area.
