干旱区尾矿污染环境的植物修复技术研究进展

干旱区矿业废弃地（尤其是尾矿及其污染环境）的治理面临着水资源短缺、土壤贫瘠、盐碱化、植物资源相对匮乏等不利因素的制约，很大程度上阻碍了该区域的生态恢复进程。基于目前国内外在干旱区尾矿污染环境治理方面所开展的研究，本文从植物修复的理论及技术方面进行了初步的综述，重点对比分析了植物提取技术和植物固定技术的优势和不足，并对相关典型应用实例进行了分析评价，最后对国内干旱区尾矿污染环境的治理研究和技术给出建议。

Research Progress on Phytoremediation to Polluted Environments by Mine Tailings in Arid Regions

In arid regions, the ecological restoration process of mine land (in particular tailings and polluted environments) is, to a large extent, hampered by various natural disadvantages, such as water shortages, infertile soil, salinization and the relative scarcity of plant resources. Based on the relative studies carried out in polluted environments at home and abroad, this paper present a preliminary review of the theory and technology to phytoremediation which focused on comparative analysis of plant extracts and plant stable technologies and provided an analysis of typical application examples, and previewed the research and technology to pollution control in arid regions.
