摘　　要：作为一种新兴的环境功能材料,生物炭以其优良的特性在土壤改良和污染修复上表现出极大应用潜力。综述了陆生和水生蔬菜重金属污染的现状、重金属修复方法、生物炭的特性及生物炭降低重金属污染有效性的作用机制和影响因素,总结了其对蔬菜产量产生的有益效应,指明了一些尚未解决的关键问题,为利用生物炭减轻蔬菜重金属污染的可行性提供理论依据和实践参考,为蔬菜的安全生产提供新的思路和方法。As a new environmental functional material, biochar showed great potential applications on soil improvement and pollution repair for its excellent properties. This paper reviewed the current status of heavy metals pollution on the terrestrial and aquatic vegetables, remediation approaches of heavy metals pollution, biochar characteristics as well as the mechanism and influencing factors of biochar reducing the effectiveness of heavy metals. In addition, the paper discussed the beneficial effects of biochar on vegetable yield and the unsolved key problems, which provided a theoretical basis and practical reference for the feasibility of utilizing biochar to reduce heavy metals pollution in vegetables, as well as some new ideas and methods for the safe production of vegetables.
