摘　　要：江西省萍乡市某煤矿为了重建健康的土壤生态环境,促进生态系统的良性循环,针对因煤矸石堆放和矿井水排放等因素导致的该煤矿塌陷区土壤中重金属含量严重超标的问题,对塌陷区0~20 cm的表层土壤进行了分层取样,利用单因子指数和综合污染指数对塌陷区土壤重金属污染指数进行了评价研究。研究分析了重金属污染分布特征,并绘制了塌陷区土壤重金属污染分布图;提出了以物理修复技术、化学修复技术、植物修复技术相结合的修复措施,可对该煤矿塌陷区重金属污染土壤实现较好的治理及修复。In order to rebuild a healthy soil ecological environment and promote a virtuous cycle of the ecosystem in a coal mine in Pingxiang City,Jiangxi Province,the heavy metal content in the soil of the coal mine subsidence area is seriously exceeded due to factors such as coal gangue stacking and mine water dis-charge.The surface soil of 0~20 cm in the subsidence area is sampled in layers,and the single factor index and comprehensive pollution index are used to evaluate the soil heavy metal pollution index in the subsid-ence area.The distribution characteristics of heavy metal pollution are studied and analyzed,and the distri-bution map of heavy metal pollution in soil of subsidence area is drawn.The remediation measures combined with physical remediation technology,chemical remediation technology and phytoremediation technology are proposed,which can achieve better treatment and remediation of heavy metal contaminated soil in the coal mine subsidence area.
