摘　　要：以甘肃省天水市麦积区花牛镇花牛村苹果种植地区土壤为研究对象采用火焰原子吸收光谱仪对土壤中的重金属元素Zn,Hg,Cu的含量进行了测定,各重金属元素的平均含量分别为:Zn的平均含量为26.27 mg/kg、Hg的平均含量为0.617 mg/kg、Cu的平均含量为11.67 mg/kg。结果表明,该地区的土壤可以安全的进行农业生产,土壤中的重金属不会通过食物链的作用对人类健康形成威胁和危害。The soil of apple planting area in Tianshui, Gansu Province michael plot Huaniu town village as the research object, the content of heavy metal element Zn, Hg, Cu in soil was determined by air-acetylene flame FAAS. The average contents of all kinds of heavy metal elements were ： the average content of zinc was 26. 27 mg/kg, the average content of mercury was 0. 617 mg/kg, the average content of coppe was 11.67 mg/kg. The results showed that the region＇s soil could be safe for agricultural production, heavy metals in the soil didn＇t threat and harm to human health through the food chain.
