摘  要:
对安徽省境内分布的4个铜矿区进行了植被和土壤调查,各个采样点土壤理化分析结果显示,铜矿土壤中Cu含量远超出正常水平,土壤基质中的Cu毒性是限制和决定区域内植物分布的主要因素。野外植物调查共记录植物82种,隶属45科,其中有6个优势科和12个优势种,各种植物在Cu转运系数和Cu积累特征上表现出较大差异。综合植物分布区土壤中的Cu含量及植物体的Cu积累特征,认为海州香薷(Elsholtzia haichowensis)、鸭跖草(Commelina communis)、茵陈嵩(Artemisia capillaries)以及酸模(Rumex acetosa)等耐性强、分布范围广的乡土物种及物种组合能够有效地提高铜污染区域土壤固定效率,在铜矿区污染环境的修复及稳定植被系统恢复重建中具有广阔的应用前景。

摘  要:
The metallophytes growing in four copper(Cu)-enriched sites along the Yangtze River of Anhui Province were surveyed to get detailed information about vegetation composition and their Cu uptake characteristics.The results indicated that the investigated sites contained extremely high Cu concentrations,which provided harsh habitats for vegetation development.A total of 82 plant species belonging to 45 families were recorded,of which 6 families were recognized as dominant families and 12 species were noted as dominant species.The promising utilization of these metallophytes for phytoremediation was discussed.Several autochthonous species or combination of species,e.g.Elsholtzia haichowensis,Commelina communis,Artemisia capillaries,and Rumex acetosa,could be employed in phytoremediation for Cu contaminated environments considering their high Cu tolerances and wide-spread distributions in China.
