摘　　要：对安徽省某500kV变电站周围土壤中的铜含量进行了测试,结果表明,该变电站周围土壤中的铜含量的中值和平均值均超过安徽地区土壤环境的平均值,但其含量均未超过二级标准值。按照单因子指数法进行评价,远小于1;按照内梅罗综合指数法进行评价,仅为0.3235,明显低于0.7的安全值,两者均表明该变电站周围土壤是清洁的,并未受到铜污染。In this reserch, the copper content of soil samples from a 500 kV substation in Anhui province were tested. The results showed that the mid - value and average value exceeded the average value of soil in Anhui area, however, they were less than the second standard values, calculated Pi was far less than I and Psynthesized was only 0. 3235 （ much lower than the safe value 0.7）, according to the methods of single factor index and Nemerow integrated index respectively. According to the above results, the soil was not contaminated by the copper grounding grid.
