传统的土壤重金属污染评级往往存在指标过多和污染程度的不确定性等问题。该研究从物元分析和关联函数出发，建立了土壤重金属污染评价的物元模型，并利用该模型对广西某蔗田土壤的重金属污染状况进行评价。结果表明，研究区农田土壤重金属污染水平处于清洁和尚清洁两级，污染程度低，与土壤内梅罗综合污染指数法的评价结果基本一致，表明该评价模型具有较高的可靠性。

The traditional evaluation model for soil heavy metal pollution consisted diverse indexes and the result ex-hibited uncertainty.Based on the matter element theory and dependency function in the extension theory, an evalua-tion model for soil heavy metal pollution was established.In the present study, the established model was used to as-sess the heavy metal contamination in a sugarcane soil in Guangxi.It was shown that the pollution level of the sugar-cane soil was between clean and good, and the evaluation result was comparable to the result made by the Nemerow index method, which proved the feasibility of this established evaluation method.
