摘　　要：煤矿废弃地造成的土壤重金属污染是一个关键性的问题;采煤区沉陷导致地表植物被破坏,植被覆盖率降低;采煤过程会导致周边土壤污染,影响土壤中微生物群落。而丛枝菌根真菌能与植物形成共生体,在增加土壤养分、增强植物耐受力以及修复重金属污染方面具有良好的效果。探讨了近年来国内外丛枝菌根真菌对煤矿废弃地如Cd等重金属污染、烃类有机化学物质污染的修复和植物生长的促进作用,以期为未来研究提供一定的思路和理论基础。Subsidence in coal mining area leads to the destruction of surface plants and the reduction of vegetation coverage.The coal mining process will lead to soil pollution and affect the microbial community in the soil.Arbuscular mycorrhizal fungi can form symbionts with plants,which have good effects in increasing soil nutrients,enhancing plant tolerance and remediation of heavy metal pollution.The remediation effects of arbuscular mycorrhizal fungi on heavy metal pollution,organic pollution,plant damage and coal gangue pollution are comprehensively discussed in recent years,in order to provide some ideas and theoretical basis for further research in the future.
