摘　　要：介绍了常用改良剂对镉污染土壤改良效果及其作用机理。在对镉污染土壤进行改良的各种措施中,化学改良措施由于其操作便利和价格低而被广泛应用。常用的改良剂包括无机改良剂和有机改良剂两大类。其中无机改良剂主要有碱性改良剂、粘土矿物、拮抗物质等,有机改良剂主要有有机固体废弃物、有机质、天然提取高分子化合物等。The method of chemical amendments on soil heavy metals＇ contamination has been widely used because of its convenience and low cost. At present, the commonly used chemical amendments include organic and inorganic ones. Organic amendments include alkalescent amendments, clay mineral and antagonism material while inorganic amendments include organic solid wastes, organic matter and natural macromolecular compounds by extraction.
