摘　　要：近年来,水体与土壤的重金属铬污染日益严重。为了更合理利用湿生铬超富集植物李氏禾进行植物修复,解决相关实际环境问题,综述李氏禾对铬的超富集耐性机制、外源物质对李氏禾吸收和转运铬的影响、李氏禾对多种重金属共富集的特性、李氏禾-微生物联合修复重金属铬污染、铬污染修复李氏禾收获物的处置等方面的研究进展,最后为其后续发展提出展望,为研究李氏禾修复重金属铬污染与其推广应用提供帮助。In recent years,water and soil heavy metal chromium pollution is increasingly serious.For rational using of hygrophyte Cr-hyperaccumulator plant Leersia hexandra for phytoremediation,and solving practical problems of environment,this paper reviewed the research progress on the mechanism of chromium hyperaccumulation and tolerance of Leersia hexandra,the effect of exogenous substances on its absorption and transfer of chromium,characteristics of the accumulation of various heavy metals,Leersia hexandra-microbial combined remediation,the disposal of the harvested Cr hyperaccumulator Leersia hexandra,and proposed the forecast,so as to provide help for the study of phytoremediation of heavy metal chromium pollution and its promotion and application.
