An experiment was conducted to analyze the physical and chemical properties of soil sample in Daliuta Mine. By the pot experiment, four dominant plants of Vitex negundo var. heterophylla, Bothriochloa ischaemum ( L. ) Keng) , Themeda triandra Forsk. var. Japonica ( Willd. ) Makino and Allium fistulosum were selected to analyze the arsenic influence on plant growth, tolerance and enrichment level. The results showed V. negundo and T. triandra can be used to prevent the arsenic pollution in Daliuta Mine.%以大柳塔矿区为例,对矿区土壤样品进行采集,分析了当地土壤的理化性质.基于盆栽试验,选取矿区荆条(Vitex,negundo var.heterophylla)、白羊草(Bothriochloa ischaemum (L.) Keng)、黄背草(Themeda triandra Forsk.var.Japonica (Willd.) Makino)、葱(Allium fistulosum)4种优势植物,分析砷对植物的生长影响规律及植物的耐性和富集水平.试验结果表明,荆条和黄背草,尤其是荆条可用于大柳塔矿区土壤砷污染的防治.
