摘　　要：本研究旨在调查晋中市煤矿区废弃地的植物多样性和重金属积累特征。通过对4个区域进行土壤理化性质检测和植物调查,我们发现矿渣堆区的土壤理化性质破坏程度最高,而开采区最低。植物多样性评估结果显示,开采区的植物多样性最高,矿渣堆区最低。在优势物种筛选中,我们选取了胡颓子、黄刺玫、金银木、艾草和蛇莓这5种植物,研究了它们对重金属的积累特征。研究发现,黄刺玫对锰(Mn)富集能力较强,金银木对铜(Cu)和锌(Zn)富集能力较高,蛇莓对镉(Cd)具有较高的富集能力。这些结果表明,晋中市煤矿区废弃地的植物多样性和重金属积累特征存在明显差异。胡颓子、黄刺玫、金银木、艾草和蛇莓可能成为修复煤矿区废弃地的候选物种。该研究结果对于指导煤矿区废弃地的生态修复具有重要意义。This study aims to investigate the plant diversity and heavy metal accumulation characteristics in the abandoned coal mining areas of Jinzhong City.Through soil physicochemical property analysis and plant surveys in four different regions,it was found that the soil physicochemical properties were most severely degraded in the slag heap area and least in the mining area.The assessment of plant diversity revealed that the mining area had the highest diversity,while the slag heap area had the lowest.Five dominant plant species,namely Euonymus alatus,Rosa dawurica,Elaeagnus angustifolia,Artemisia argyi,and Rubus parvifolius,were selected,and their accumulation characteristics of heavy metals were studied.It was observed that Rosa dawurica exhibited strong accumulation of manganese(Mn),Elaeagnus angustifolia had high accumulation of copper(Cu)and zinc(Zn),and Rubus parvifolius showed significant accumulation of cadmium(Cd).These findings indicate distinct differences in plant diversity and heavy metal accumulation characteristics in the abandoned coal mining areas of Jinzhong City.Euonymus alatus,Rosa dawurica,Elaeagnus angustifolia,Artemisia argyi,and Rubus parvifolius may serve as candidate species for the ecological restoration of abandoned coal mining areas.The results of this study are of significant importance in guiding the ecological restoration of coal mining areas.
