摘　　要：通过收集我国30多个垃圾填埋场的土壤8种重金属数据,应用三角模糊数理论,结合各种重金属的生物毒性,构建了基于三角模糊数的地累积指数填埋场土壤重金属综合污染评价模型。结果表明:采用确定的地累积指数和采用三角模糊数来评价填埋场土壤重金属污染状况时,两者存在差异。采用三角模糊数的重金属污染综合评价结果更具指导性。According to the data of 8 kinds of heavy metals in more than 30 waste landfill sites, using the theory of triangular fuzzy numbers, combining with various heavy-metal biotoxicity, the integrated pollution evaluation model for heavy-metal pollution that based on triangular fuzzy numbers was built. The results showed that it had a certain difference between the adoption of identified cumulative index and triangular fuzzy numbers when evaluating the pollution of heavy metals in the soil of waste landfill sites. The result of comprehensive evaluation of heavy-metal pollution that using triangular fuzzy numbers was more instructional.
