摘　　要：改良剂原位治理已成为酸性重金属污染土壤治理最主要的手段,其中选择经济有效的药剂成为该技术的关键。本研究系统阐述了国内外主要采用的药剂,基于钢渣的理化性质,系统地分析了钢渣中的成分对土壤pH值、重金属活性和土壤养分的作用,指出了钢渣应用于酸性轻中度重金属污染土壤治理的潜力,以期为其实际应用提供参考依据。In situ treatment with amendment has become the most important method for remediafion of acidic heavy metal contaminated soil, and the selection of cost-effective amendments is the key of this measure. This study de- scribes the major domestic and foreign fixed-stabilizing amendments used, and systematically analyses the role of the composition of the slag on adjusting soil pH value, heavy metal activity and soil nutrients based on the physicochem- ical properties of slag, pointing out the potential of steel slag applied in remediation of heavy metal contaminated soil to provide theoretical reference for remediation of heavy metal contaminated soil.
