摘要
对现试行的绿色食品产地土壤环境质量现状评价标准提出几点修正意见:建议以国家土壤环境质量标准(GB15618 -1995)为绿色食品产地土壤环境质量现状的评价标准 ;综合评价分级标准应采用:P 综 ≤0.85 ,非污染 ;0.85<P 综 ≤1.71 ,轻污染 ;1.71<P 综≤2.56 ,中度污染 ;P 综>2.56 。
Several recommendations have been offered to soil environmental quality assessment for green-food production area: including utilization of the National Soil Environmental Quality Standard(GB15618-1995) as the soil quality assessment standards for green-food production area, in replace of employment of the background values or checked-spots of soil. It was suggested in this paper that if a soil environmental integrative index(P) was equal to or less than 0.85, the soil could be considered as non-polluted; while 0.85<P≤1.71, low-grade polluted; 1.71<P≤2.56, medium-grade polluted; and P>2.56, high-grade polluted, respectively.
