摘　　要：通过对城市污泥和尾矿废弃地理化性质以及重金属含量的分析,结合污泥土地利用的有利因素和限制性因素,讨论城市污泥用于尾矿废弃地土壤改良的可行性,提出城市污泥可以作为提高尾矿废弃地土壤肥力、改良土壤理化性质、促进植被恢复生长的土壤改良剂,从而实现尾矿废弃地生态恢复的目的。Through the analysis on physicochemical property and heavy metal content of sewage sludge and soil from mining tailing, whether municipal sewage sludge applied in mining tailing was discussed based on favorable factors and limiting factors of sludge land utilization. The conclusion was that sewage sludge may be used as the soil amendment for raising soil fertility, improving soil physiochemical properties and promoting vegetation restoration, so as to realize the purpose of ecological restoration in mining tailing.
