摘　　要：对某城市的5个不同功能区进行土壤采样,并对每个采样点的土壤应用X射线荧光光谱仪测试其8种重金属的含量,利用富集因子计算每个功能区8种重金属的污染程度等级的隶属度,然后利用模糊数学方法对5个功能区的污染程度进行了综合评价,最后得到5个功能区重金属污染程度的排序向量。由此可以判定每个功能区受污染程度,其中工业区和主干道路区重金属污染程度最轻,生活区和公园区重金属污染程度较重。The soil samples were collected in five different functional areas of the certain city,and the concentrations of eight kind of heavy metals were tested by X-ray fluorescence spectrometer in each sample soil.The memberships of eight kind of heavy metal pollution levels for each functional area were calculated by the enrichment factors,and then the pollution degree of the five functional areas was comprehensively evaluated by fuzzy mathematical method.Finally,the priority vectors of pollution degree of the heavy metals in the five functional areas were obtained which could show the pollution degree of each functional area,and the industrial park and area alongside trunk roads belonged to the lightest heavy metal pollution one,while the living quarters and central park district did suffer from the heavy metal pollution.
