摘　　要：以云南某选矿厂类芦为研究对象,就类芦(Neyraudia reynaudiana(kunth.)Keng)对Pb的超富集特性、转运系数、富集系数及生长速度进行了初步研究,结果表明,类芦具有抗逆境能力强、生长迅速、Pb转运系数高等特点,有望调控成为较理想的土壤铅污染植物修复资源.In this paper Neyraudia reynaudiana is researched tion coefficient, accumulative coefficient and growing in lead for its hyperaccumulative property, lead transformacontaminated soil in Datun concentrator. It is found out that Neyraudia reynaudiana has the properties of strong endurance to adverse environment, fast growing and high lead transformation coefficient. It is suggested that Neyraudia reynaudiana can be controlled to remedy soils contaminated by lead.
