摘要
土壤重金属污染是当前亟须解决的问题.与其他修复技术相比,植物修复因其具有环境友好且不产生二次污染等优点而备受关注.超富集植物是一类具有特殊生理特性的植物,对土壤重金属等有害物质的吸附能力远高于普通植物,具有高积累性和高耐受性的特点.超富集植物的修复存在修复周期过长、修复效率低和修复目标较为单一等局限性,因此施行一系列强化措施成为促进植物高效修复的有效途径.分析了当前重金属污染和修复技术特点,综述了重金属超富集植物研究现状和强化措施,并对此进行了总结与展望.
Abstract
Soil heavy metal pollution has become an urgent problem to be solved,among many existing remediation technologies,phytoremediation has become a hot research technology because of its environmental friendliness and will not produce secondary pollution,super-enriched plants are a kind of plants with special physiological characteristics,the adsorption capacity of heavy metals and other harmful substances in the soil is much higher than that of ordinary plants,with the advantages of high accumulation and high tolerance.However,the restoration of super-enriched plants also has the limitations of too long restoration cycle,low restoration efficiency and more specific restoration.In this regard,the implementation of a series of strengthening measures has become an effective way to promote efficient plant restoration.In this paper,the characteristics of the current heavy metal pollution and remediation technology are analyzed,the research status and strengthening measures of heavy metal super-enriched plants are reviewed,and finally the prospects are summarized.
