中文摘要：

通过对焦作市大马矿煤矸山进行野外调查采样,检测其周围土壤中重金属（Cu、Zn、Pb、Cr）含量并分析周围自然生长的乡土植物对重金属（Cu、Zn）吸收累积的特性。结果表明,矿区周围土壤主要受Zn污染和Cu污染。花椒和芦苇具有较强的Cu吸收能力并且芦苇地下部分Cu富集系数大于1,苦荬菜和酸模的Cu转运系数大于1。而17种乡土植物的Zn富集系数均未超出1,仅有刺儿菜的Zn转运系数大于1。

英文摘要：

A study was conducted to investigate the contents of heavy metals（Cu, Zn, Pb and Cr） in the soil around coal gangue dump（Dama Mine, Jiaozuo, China）. The contents of Cu and Zn in native plants around coal gangue dump were determined to assess the metal absorption and accumulation characteristics in these plants. The results showed that the soil was polluted by Zn and Cu. Zanthoxylum bungeanum and Phragmites australis had a strong ability to absorb Cu. The bioconcentration factor for Cu of the Phragmites australis root system was greater than 1. The translocation factor of Ixeris denticulata and Rumex acetosa for Cu were greater than 1. In addition, the bioconcentration factors of the 17 plant species for Zn were not over 1. Only the translocation factor of Cirsium setosum for Zn was greater than 1.
