重金属污染土壤及场地的植物修复技术发展与应用

摘要

重金属污染土壤及场地的治理工作迫在眉睫,植物修复技术以其成本低、不破坏土壤生态环境、无二次污染、易被公众接受等优点,受到了学术界的广泛关注.近年来,国内外在植物修复技术的植物资源筛选、调控技术、修复植物产后处理等方面进行了广泛的研究.植物修复已经从实验室阶段走向了田间示范和推广应用阶段.现就近年来植物修复技术在重金属污染土壤和场地的发展和应用方面进行了综述.%Heavy metal pollutions in soils and sites are becoming more and more serious, and their remediation is receiving extensive attention nowadays. Due to its low-cost and environment-friendly, phytoremediation is considered to be a potential usable technique for soil remediation. During the past decades, there have been significant improvements in phytoremediation, including plant species scanning, remediation control techniques,post-treatments of plants bio-mass, demonstration in field-scale, and practical applications. This review provides an overview of the development and application of phytoremediation on the remediation of heavy metal contaminated soils and sites.
