摘　　要：利用熵权法建立了基于熵权的属性识别模型.采用土壤环境质量标准GB15618-1995,用此模型对南京市六合区的水稻田土壤重金属污染进行评价.实例应用表明属性识别理论应用于土染重金属污染综合评价是可行的,评价结果比较合理.Attribute recognition theoretical model is set up making use of entropy weight.Based on the demand of Standard of Soil Environmental Quality Assessment （GB 15618-1995）,soil environmental quality of paddy field in Nanjing,plowland in Kunshan and vegetable field in Urumchi were assessed in attribute recognition theoretical method.The results were appropriate and showed that the attribute recognition theoretical model can be used in the heavy metal pollution degree judgment of soil.
