采集合肥市某草莓基地区域100个样点的土壤，测定表层土壤（深度分别为0～10 cm和10～20 cm）的6种重金属（Cd、Hg、As、Pb、Cr和Cu），利用地累积指数方法对草莓种植土壤重金属的污染程度和生态风险进行评价，并结合多元统计分析探讨重金属来源。结果表明，Pb、Cd、Hg、Cu和Cr虽对草莓基地部分区域的土壤有一定程度的累积和污染，但污染风险低；主成分分析表明，Pb、Cd、As、Cu和Hg源于人类农业活动，Cr源于土壤母质及风化累积。显示草莓基地整体区域的土壤重金属生态风险低，种植基地土壤重金属未对草莓质量安全产生影响。
The contents of six heavy metals (Cd, Hg, As, Pb, Cr and Cu) were measured in the surface soil (depth in 0-10 cm and 10-20 cm, respectively) from 100 sampling sites in a strawberry base area in Hefei, and the degree of contamination and ecological risk of heavy metals in strawberry growing soil were evaluated using the ground accumulation index method and combined with multivariate statistical analysis to explore the sources of heavy metals. The results showed that Pb, Cd, Hg, Cu and Cr had accumulated and polluted soil in some areas of strawberry base to a certain extent, but the pollution risk was low. The principal component analysis showed that Pb, Cd, As Cu and Hg were derived from human agricultural activities. Cr originates from soil parent material and weathering accumulation. It showed that the ecological risk of soil heavy metals in the whole area of strawberry base was low, and the heavy metals in the soil have not affected the quality and safety of strawberries.
