美国矿山废弃地生态修复案例研究

Study on the Ecological Restoration Case of Mine Waste Land in the United States

随着我国矿业的发展,产生了大量生态退化、水土流失严重的矿山废弃地,其生态修复迫在眉睫。美国矿山废弃地的生态修复工作起步较早,借鉴其成功经验是推动我国矿山废弃地生态修复工作的有效途径。在分析美国矿山废弃地分布的基础上,对美国5个矿山废弃地的生态修复案例进行深入研究,从土壤改良、水体净化、植被重建3个方面总结归纳案例的生态修复技术要点和特色,为我国矿山废弃地的生态修复工作提供借鉴。

With the development of mining industry, a large number of ecological degradation, serious soil erosion of the mine abandoned land, the ecological restoration is imminent. The ecological restoration of abandoned land in the United States of America has started earlier, and using the successful experience is an effective way to promote the ecological restoration of mining wasteland in China. On the basis of analysis of the distribution of American mines, 5 cases of ecological restoration in the United States were studied. The main points and features of the ecological restoration technology were summarized from 3 aspects of soil improvement, water purification and vegetation reconstruction, so as to provide reference for the ecological restoration of mining wasteland in China.
