摘　　要：通过对北京城近郊土壤中Cd污染两种不同评价方法的对比研究发现,在对某一区域进行土壤环境质量评价时,若研究区内存在不同质地的土壤,则由于不同质地土壤的自净能力的不同,应采用不同的评价标准进行分区评价。建议多目标地球化学填图中进行土壤环境质量评价时,采用本方法。Based on the comparative analysis of two evaluation methods of soil Cd pollution in the suburbs of Beijing city, it has been found that the soil grain is different from zone to zone even in same investigating area, resulting in different capability of self-cleaning. Different evaluation criterion should thus be adopted from zone to zone. It is suggested that the evaluation procedure for soil environment used in the this study can be generally adopted in multi-purpose regional geochemical mapping.
