摘　　要：针对高寒干旱地区某有色金属冶炼区及周边地区可能出现的土壤重金属污染问题,实施了该研究区土壤和乡土植物的取样、重金属含量测定工作,分析评价了土壤污染现状,并筛选出了对重金属富集性强的乡土植物。结果表明,该有色金属冶炼区的土壤存在锌、镉的污染。具有富集锌、镉能力的乡土植物有11种,其中对污染土壤具备修复能力的乡土植物为刺儿菜与巴天酸模。According to the heavy metal soil pollution might occur in the non-ferrous metal smelting area and surrounding area in Alpine arid areas,soil and native plant samples of the operation area were collected for determination of the heavy metal content.The soil pollution situation was analyzed;and native plants with strong enrichment ability of heavy metals were screened.Results showed that soil in the non-ferrous metal smelting area was with zinc and cadmium pollution.11 kinds of native plants with enrichment ability of zinc and cadmium were selected,among which Cirsium setosum（Willd.） MB.and Rumex patientia L.had remediation ability to the contaminated soil.
