废弃的金属矿山废物会造成严重污染，并对当地环境造成美学影响。植被覆盖的使用提供了一种具有成本效益和环境可持续性的方法来稳定和回收废物，如矿山废弃物和尾矿。含金属废物的许多特点往往不利于成功地建立植被，最明显的是植物毒性水平的残留重金属，低营养状况和不良的物理结构的基层。目前的重新植被和开垦办法包括改良和适应性战略，以允许植物生长并鼓励随后的植被发展。根据废物的特性，温带和干旱、亚热带地区可采用不同的植被重建技术。这些措施包括直接播种商业上可获得的植物、使用覆盖物和屏障系统以及加强自然重新植被进程。(C)2000爱思唯尔科技有限公司版权所有。
Abandoned metalliferous mine wastes can result in severe pollution and have aesthetic impacts on the local environment. Use of a vegetation cover gives a cost-effective and environmentally sustainable method of stabilising and reclaiming wastes such as mine-spoils and tailings. Many characteristics of metalliferous wastes are often inimical to successful vegetation establishment, most notably phytotoxic levels of residual heavy metals, low nutrient status and poor physical structure of the substratum. Current approaches to revegetation and reclamation involve both ameliorative and adaptive strategies to allow plant establishment and encourage subsequent vegetation development. Different techniques of revegetation are available for temperate and arid, subtropical regions depending on the characteristics of the waste. These include direct seeding with commercially available plants, use of cover and barrier systems and the enhancement of natural revegetation processes. (C) 2000 Elsevier Science Ltd.
