摘　　要：通过对典型铬渣堆存场地铬(Ⅵ)迁移路径分析,说明对含铬(Ⅵ)废物/土壤的处置/修复,阻止铬(Ⅵ)进一步扩散迁移已成为保护地下水资源的当务之急。在实验中初步筛选出高羊茅、芦苇、马特、蓖麻4种耐铬植物,其生长发育受铬(Ⅵ)影响较小,且与微生物协同作用还可有效还原土壤中铬(Ⅵ),为控制铬(Ⅵ)污染场地土壤、地下水污染与大气扬尘污染开辟了一条新途径。The Chromium （Ⅵ）transportation way in the typical chromic slag disposal site is studied. The results show that it is urgent to treat the polluted soils and prevent the further Chromium （Ⅵ） transportation to groundwater. Four chromium tolerant plants ,such as Lolium Multiflorum, Bulrush, Martiella ,Castor-Oil Plant are screened because they are influenced less and can work with microbe to reduce Cr（Ⅵ）,which provides the new way to control Chromium （Vi）contaminated soil,groundwater and air.
