摘　　要：由于复垦区域土壤中重金属污染问题的日益突出,对重金属污染物进行生态修复已经迫在眉睫。针对这一问题,进行复垦区域土壤中重金属污染物的分布特性及生态修复研究。通过分析复垦区域土壤中重金属污染物的分布特性,得出重金属污染物会形成垂直分布特征,随土层深度的增加,复垦区域土壤中重金属污染物的含量整体呈下降趋势;采用微生物修复,对重金属污染物介质进行净化;添加还原性有机物质,利用矿化固定作用对重金属污染物进行吸附,从而实现复垦区域土壤中重金属污染物生态修复。Due to the increasingly prominent problem of heavy metal pollution in the soil of reclamation area,it is urgent to carry out ecological remediation of heavy metal pollutants.To solve this problem,the distribution characteristics and ecological restoration of heavy metal pollutants in reclaimed soil were studied.Based on the analysis of the distribution characteristics of heavy metal pollutants in the soil of reclamation area,the vertical distribution characteristics of heavy metal pollutants will be formed.With the increase of soil depth,the content of heavy metal pollutants in the soil of reclamation area will decrease as a whole;the medium of heavy metal pollutants will be purified by microbial remediation;the medium of heavy metal pollutants will be purified by adding reducing organic substances and heavy metal will be fixed by mineralization Metal pollutants are adsorbed to realize the ecological restoration of heavy metal pollutants in the soil of reclamation area.
