为了科学评价广东省明山煤矿区废弃地土壤重金属污染情况，于2010年11月至2011年3月，采集明山煤矿区废弃地受重金属污染的5个样点的土壤样品，运用原子吸收分光光度法对土壤中7种重金属元素进行测定。结果表明，①土壤pH在2.87~6.16，土壤较贫瘠。②土壤污染主要是Cd、Mn污染，其中，Cd平均含量为2.052 mg/kg（0.759~3.109 mg/kg），超标严重；Mn 平均含量为421.215 mg/kg （387.057~488.660 mg/kg），污染严重。③从内梅罗综合污染指数看，样点1、样点4、样点5为极重污染，样点2、样点3为中度污染。

ln order to appraise scientifical y the heavy metal contamination in waste-land of coalmine tailing in Mingshan of Guangdong, the 5 soil samples in wasteland of coalmine tailing were col ected in November 2010 to March 2011. The 7 heavy metals content in the contaminated soil was measured by atomic absorption spec-trophotometry. The results showed the pH of the wasteland soil ranged from 2.87 to 6.16, and the soil was relatively infertile. The soil was mainly pol uted by Cd and Mn. The Cd content in wasteland soil ranged from 0.759 mg/kg to 3.109 mg/kg with an average content of 2.052 mg/kg, which was much higher than the standard content. The Mn content ranged from 387.057 to 488.660 mg/kg with an average content of 421.215 mg/kg, which was much higher than the standard content. The Nemerow integrated pol ution indexes showed the sample 1, sample 4 and sample 5 were of heavy pol ution, and sample 2 and sample 3 were of moderate pol ution.
