摘　　要：在物元分析的基础上,结合模糊权重理论与层次分析方法,构建用于评价地下水水质的模糊权物元分析模型。应用此模型对徐州市的重要水源地——张集水源地的地下水水质进行了综合评价。选取数据较为完整的20个监测井的监测数据进行评价。结果表明,研究区的20个采样点水质为Ⅱ、Ⅲ级的占95%,绝大多数地下水水质较好,符合饮用水的要求。与投影寻踪法和模糊概率法的评价结果比较发现,得出的评价结果与以上2种评价结果基本一致。Based on matter-element analysis and applied fuzzy weight and AHP, matter-element model based on fuzzy weight was established to evaluate groundwater quality. The model was applied to evaluate groundwater quality of Zhangji, which was a main well field in Xuzhou, and twenty wells were selected. The results showed that 95% of the water samples in the well field could be rated either level Ⅱ or Ⅲ according to the water quality standard. The groundwater samples were of good quality and fit the quality standard of potable water. The results were as the same as projection pursuit model and fuzzy probability model.
