本文综述了矿山土壤修复的生态学方面，特别强调了在有毒金属矿区维持长期可持续的植被。金属开采土壤是一种非常不稳定的人工栖息地，将成为空气和水污染的污染源。建立植被覆盖对于稳定裸露区域和尽量减少污染问题至关重要。除了修复场地不利的物理和化学特性外，选择适当的植被也很重要。植物稳定和植物萃取是金属污染土壤中常见的两种植物修复技术，分别用于稳定有毒矿渣和从矿渣中去除有毒金属。应添加土壤改良剂，以帮助稳定矿山的破坏，并相应地提高金属的吸收。(C) 2002 Elsevier Science Ltd.版权所有。
This paper reviews the ecological aspects of mined soil restoration, with special emphasis on maintaining a long-term sustainable vegetation on toxic metal mine sites. The metal mined soils are man-made habitats which are very unstable and will become sources of air and water pollution. Establishment of a vegetation cover is essential to stabilize the bare area and to minimize the pollution problem. In addition to remediate the adverse physical and chemical properties of the sites, the choice of appropriate vegetation will be important. Phytostabilization and phytoextraction are two common phytoremediation techniques in treating metal-contaminated soils, for stabilizing toxic mine spoils, and the removal of toxic metals from the spoils respectively. Soil amendments should be added to aid stabilizing mine spoils, and to enhance metal uptake accordingly. (C) 2002 Elsevier Science Ltd. All rights reserved.
