摘　　要：[目的]研究乌鲁木齐市土壤中Cu的污染现状。[方法]采取Tessier连续提取法,对乌鲁木齐市6种不同功能区表层土壤中Cu的含量及其化学形态分布进行了研究。[结果]不同功能区中,不同形态的Cu分布有较大的差异。其中,工业区、交通密集区和商业区的土壤中活性态重金属所占比例较高,居民区、风景区和文教区的土壤中的重金属以残渣态为主。[结论]乌鲁木齐市各功能区土壤中存在不同程度的Cu污染。[Objective] The study aimed to study the pollution situation of Cu in urban soil of Urumqi. [Method] The concentration and the chemical speciation of Cu in urban soils of Urumqi were studied by using Tessier sequential extraction procedures. [Result] The results indicated that there were big difference in different Cu patterns at different function areas. The proportion of active fraction of heavy metal was very high in the soil of industry area, traffic area and business area. Heavy metal were dominated by the residual fraction in culture and e.ducation area, living area and scenic spot soils. [Conclusion] There were different degree pollution of Cu in different function areas soll of Urumqi.
