摘　　要：[目的]铜尾矿库的修复及以后的相关研究提供科学依据。[方法]采用火焰-原子吸收分光光度计和石墨炉原子吸收分光光度法测定土壤中重金属含量。[结果]尾矿土壤中的Cu、Zn、Cd含量均较高,其中Cu、Cd的含量分别是国家土壤环境质量二级标准的1.04～1.30倍和6.58～9.34倍。[结论]重金属污染会降低土壤质量,进而影响该地区作物的质量。凤凰山尾矿区近年来种植的作物,对重金属元素的吸收效果不明显。这为后期的土壤改良和种植作物的选择提供了一定的依据。[Objective]The study aimed to provide the scientific basis for the restoration of copper tailings reservoir and the further related research.[Method]The soil heavy metal contents were determine by flame-atomic absorption spectrophotometer and graphite furnace atomic absorption spectrophotometry.[Results]The Cu,Zn and Cd contents in the soil of tailings were higher,in which,the contents of Cu and Cd were 104-1.30 times and 6.58-9.34 times of the secondary standard of national soil environmental quality,resp.[ Conclusion ] The heavy metal pollution could reduce the soil quality,thus affecting the quality of crops in this area.The crops planted in copper-tailings reservoir of Fenghuang Mountain in recent years had not obvious effects on the absorption of the heavy metal elements.The study provided some references for later improvement of soil and choice of the planting crops.
