【Abstract】 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.更多还原
