摘  要：
有色金属矿区周边土壤是典型的人为污染土壤,人为污染土壤具有特殊的磁化率特征.本文选取有色金属矿区表层土壤来研究土壤磁化率与Pb、Zn、Cd的关系,研究结果表明:兰坪与会泽土壤表现出不一样磁性特征,兰坪磁化率变异系数较大.兰坪和会泽均表现为Cd污染最为严重.兰坪土壤仅重金属Cd与磁化率 χlf相关性显著;有效态Pb、Zn、Cd均与磁化率 χlf的相关性显著;而会泽土壤仅Pb与磁化率 χlf呈显著相关关系;有效态仅Zn与磁化率 χlf的相关性达到显著水平.兰坪土壤pH、电导率与磁化率 χlf相关性较好,有机质与磁化率 χlf的相关性不显著;会泽土壤pH、电导率及有机质与磁化率的相关性均未达到显著水平.本研究为矿区土壤环境状况调查提供参考,同时也为找寻土壤磁化率 χlf和重金属的关系、实现快速掌握土壤重金属污染状况提供理论基础.

摘  要：
Soil around non-ferrous metal mining usually is typical man-made polluted soil. The polluted soil has a special magnetic susceptibility. In this paper, the relationship was studied between soil magnetic susceptibility(χlf) and Pb, Zn and Cd contents in topsoils around non-ferrous metal mining. The results showed that soils in Lanping and Huize mining had different χlf, and the coefficient of variation of χlf was larger in Lanping mining than in Huize mining. Both Lanping and Huize mining showed most serious soil Cd pollution. Total Cd and available Pb, Zn, Cd around Lanping mining had significant correlation with χlf(P<0.01). Total Pb and available Zn around Huize mining had significant correlation with χlf(P<0.05). Soil pH and conductivity around Lanping mining had significant correlation with χlf while no significant correlation was found between organic matter and χlf. Soil pH, conductivity and organic matter around Huize mining had no significant correlation with χlf. This study provided a reference for the investigation of soil environment in the mining area, and provided a theoretical basis for finding the relationship between soil magnetic susceptibility and heavy metals, and thus for rapid understanding the status of soil heavy metal pollution.
