摘　　要：为寻找铅污染土壤净化和景观化的花卉植物,采用盆栽方法,研究了3种花卉对铅污染土壤的修复能力。结果表明,3种花卉中送春花(Godetia amoena)地上部吸收富集铅的量最大,积累铅能力最强,其次为勿忘我(Limonium sinuatum),马络葵(Malope trifida)吸收积累铅能力最弱。在Pb浓度为1 000 mg/kg时,3种花卉耐性均较强,可用作铅污染土壤的稳定修复植物。In order to search flower plants which could purify and beautify Pb -contaminated environ-ment,3 kinds of flowers were screened to determine their soil remediation abilities by pot method.The results showed that Godetia amoena had the strongest capability of accumulating Pb in aerial part,followed by Limoni-um sinuatum,and Malope trifida had the weakest.When the Pb concentration was 1 000 mg/kg,3 kinds of flowers all exhibited strong endurance,which could be used for soil stabilization remediation.
