摘　　要：工业发展中产生的重金属污染土壤是环境污染中的一个重要问题。对Cd含量超标的土壤进行植物修复是一种环境友好、无二次污染和修复比较彻底的优势策略。由于土壤重金属污染源的特异性和复杂性,以及受到周围生态环境和物种的限制,在制定植物修复策略时需要多方面综合考虑。文章以植物修复为主,按植物功能分为观赏植物、经济植物、能源植物、药用植物、粮食作物和蔬菜植物等,比较分析富集能力,并联合动物修复和微生物修复对Cd污染土壤的修复展开论述,分析利弊,以期为植物修复Cd污染土壤提供策略,并为合理制定修复方案提供参考。The rapid development of the economy and the process of industrialization have brought severe environmental pollution and ecological damage.Heavy metal pollution of soil caused by industrial development is an important issue in environment pollution.Phytoremediation of Cd-contaminated soils is an environmentally friendly,non-secondary pollution and relatively thorough remediation strategy.Due to the specificity and complexity of heavy metal polluted soil sources,as well as the limitations of the surrounding ecological environment and species,it is necessary to comprehensively consider various aspects when formulating phytoremediation strategies.In this study we mainly focus on phytoremediation,combining with animal remediation and microbial remediation to remediate cadmium-contaminated soils,and analyze its advantages and disadvantages.We are expected to provide effective strategies for the implementation of bioremediation in Cd-contaminated soils,as well as references for the rational formulation of remediation programs.
