| 摘 要： | 通过对陕西长武苹果园地土壤样品采集和实验分析,依据无公害果园产地土壤环境质量标准和绿色食品产地土壤环境质量标准,对其土壤环境质量进行了评价。结果表明:以无公害果园产地土壤环境质量为评价标准,长武果园土壤重金属污染程度有NiAsCrZnCuPb的特征,土壤重金属综合污染指数为0.489;以绿色食品产地土壤环境质量为评价标准,长武果园土壤重金属污染程度有CrAsPbCu的特征,土壤重金属综合污染指数为0.715。因此,其土壤环境质量应判定为尚清洁。环境质量评价过程揭示了Ni、Cr存在潜在污染可能,特别是Cr含量已达绿色食品产地土壤环境质量标准的警戒线,所以应将它作为今后监测的重点并引起足够的重视。

| Abstract: | Based on the analysis of soil samples collected from Changwu apple orchard,Shaanxi Province,the soil environmental quality was evaluated by using standards for pollution-free fruit orchard and standards for green food production area.The results indicated that according to the former standards,contaminated degree for soil heavy metals was Ni>As>Cr>Zn>Cu>Pb and the index of synthetic soil heavy metals pollution was 0.489.And according to the latter standard,the contaminated degree of soil heavy metals was Cr... |
