摘　　要：为进一步解决当前重金属对土壤严重污染不可逆转且高积累性的问题,以黄棕土壤为例,在对其基础理化性质分析的基础上,通过实验方式研究了微米级羟基磷灰石、纳米级羟基磷灰石以及骨粉对土壤中重金属有效态含量的减少、对土壤中重金属残渣态含量的增加两个层面反应不同含磷材料对土壤中重金属的治理效果,对指导今后土壤重金属治理提供扎实的理论基础。In order to further solve the problem of irreversible and high accumulation of heavy metals on soil,taking yellow brown soil as an example,based on the analysis of its basic physical and chemical properties,the treatment effect of different phosphorous containing materials on heavy metals in soil was studied through experiments on the reduction of the effective state content of heavy metals in soil and the increase of the residual state content of heavy metals in soil by micro hydroxyapatite,nano hydroxyapatite and bone powder,which provided a solid theoretical basis for guiding the treatment of heavy metals in soil in the future.
