摘　　要：将非线性可拓综合评价方法应用于土壤重金属污染评价。分析了土壤重金属污染的影响因素,建立了土壤重金属污染评价的物元模型。将多指标土壤重金属污染的目标评价归结为单目标决策,比较简明确切地反映出土壤重金属污染。The nonlinear extension multi-factorial evaluation method is used to assess soil heavy metal pollution. The author analyzes elements that influence soil heavy metal pollution builds up a matter-element model for assessing soil heavy metal pollution with the nonlinear extension multi-factorial evaluation and transforms the multi-index assessment into single-object decision-making, which may clearly and accurately reflect integrative level of the pollution.
