摘　　要：采用分光光度法测定广西南丹县大厂镇矿区36个土壤样品中的Fe、Zn、Cu含量。结果表明南丹县大厂矿区土壤中Fe、Zn、Cu含量较高,其中最高含量分别为11 890.73 mg/kg、7 582.87 mg/kg、1 540.78 mg/kg,平均含量分别为10 293.65 mg/kg、4 329.31 mg/kg、589.16 mg/kg。土壤中Fe、Zn、Cu的平均含量分别超过世界土壤背景值、中国土壤背景值、广西土壤背景值的257.14、48.10、19.64;367.33、53.85、26.07;298.12、9.24、28.34倍。Fe,Zn and Cu in 36 soil samples of Dachang mine in Nandan are determined by Vis spectroscopy and the result shows a high content of Fe,Zn and Cu at this area. The highest contents of Fe , Zn and Cu are 11 890.73 mg/kg,7 582.87 mg/kg and 1 540.78 mg/kg respectively. The average content of Fe is 10 293.65 mg,/kg which exceeds the soil background values of the world and China, Guangxi 257.14, 367.33 and 298.12 times respectively. The average content of Zn is 4 329.31 mg/kg which exceeds the soil background values of the world and China, Guangxi 48. 10, 53.85 and 9.24 times respectively . The average content of Cu is 589. 16 mg/kg exceeds the soil background values of the world and China , Guangxi 19.64, 26.07 and 28.34 times respectively.
