摘　　要：对模糊数学理论在土壤重金属污染评价工作中的应用策略进行了深入分析,详细介绍了模糊数学方法在矿区土壤重金属污染定性判定的基本流程,提出了用于土壤重金属评价的因素集、评价集与权重集的具体内容与计算方法,通过基于隶属度函数的模糊关系矩阵建立综合评价模型,并利用该模型对榆林市神树畔井田矿区的重金属污染情况进行了评价。评价结果显示,该矿区土壤重金属污染较为严重,需要适当地调整煤炭资源的开发方式。The application strategy of fuzzy mathematics theory in the evaluation of soil heavy metal pollution was deeply analyzed,the basic process of fuzzy mathematics method in the qualitative determination of soil heavy metal pollution in mining area was introduced in detail,and the specific content and calculation method of factor set,evaluation set and weight set for soil heavy metal evaluation were put forward.The comprehensive evaluation model was established by fuzzy relation matrix based on membership function,and this model was used to evaluate the heavy metal pollution in shenshupan mine area of Yulin City.The results showed that,the heavy metal pollution in the mine area is serious,and the development mode of coal resources needs to be adjusted appropriately.
