摘　　要：经济社会发展对矿产资源的需求不断增大,矿山大规模的开采,以及开采产生的大量废弃物使原有的地形、地貌和植被遭到严重破坏,水土流失严重,对矿区及周边的生态安全构成威胁,矿山废弃地的生态恢复与重建已成为矿区环境治理和发展绿色矿山不可或缺的一项任务。通过对矿山废弃地的环境特点和生态恢复与重建影响因素及对策进行分析,指出加强对土壤基质改良和先锋植物种类选择的研究是今后矿山废弃地生态恢复与重建的工作重点,同时开展土壤-植被系统长期的定位监测研究,探寻土壤与植物群落的演替规律与作用机制,为矿山废弃地水土保持生态恢复与重建提供科学依据。With the increasing demand of economic and social development for mineral resources,large-scale mining of mines and a large number of waste produced by mining have seriously damaged the original topography,geomorphology and vegetation,caused the serious soil erosion,which posed a threat to the ecological security of mining areas and surrounding areas.Ecological restoration and reconstruction of abandoned mines has become an indispensable task for environmental governance and development of green mines in mining areas.By analyzing of environmental characteristics,influencing factors and countermeasures of ecological restoration and reconstruction of abandoned mines,it is pointed out that strengthening the research on soil matric improvement and selection of pioneer vegetation species is the focus of ecological restoration and reconstruction of mine wasteland in the future.At the same time,the long-term positioning monitoring of soil-vegetation system is carried out to explore the succession law and mechanism of soil and vegetation community,and provide scientific basis for soil and water conservation ecological restoration in abandoned mines.
