摘　　要：为促进环境保护、推动可持续发展、改善生态环境,研究基于植物修复的矿山废弃地重金属污染及生态环境改良技术。分析矿山污染现状,配合外来的先锋植物马蔺、黄菖蒲,修复矿山废弃地土壤的铅污染、锌污染,将筛选的植物种子种植于重金属污染严重区域,并分析种植后,土壤生态环境变化。此方法修复后,矿山废弃地重金属污染土壤中全氮、有机质、有效磷和速效钾含量和修复前相比明显提升,土壤酶活性得到优化,证明该修复技术在修复矿山废弃地重金属污染及生态环境问题中具有可行性。To promote environmental protection,promote sustainable development,and improve the ecological environment,this study researches on heavy metal pollution and ecological environment improvement technologies based on plant remediation in abandoned mining areas.It analyzes the current situation of mining pollution,cooperates with foreign pioneer plants such as Iris and Acorus to restore lead and zinc pollution in the soil of abandoned mining areas.The selected plant seeds were planted in areas with severe heavy metal pollution to analyze the changes in the soil ecological environment after planting.After this method of remediation,the content of total nitrogen,organic matter,available phosphorus,and available potassium in heavy metal polluted soil in abandoned mining areas significantly increased compared to before remediation.The soil enzyme activity was optimized,proving the feasibility of this remediation technology in repairing heavy metal pollution and ecological environment problems in abandoned mining areas.
