摘　　要：通过构建模糊数学模型评价济南某引黄水库的进水口和出水口的水质,评价结果发现该引黄水库进水口和出水口分别属于Ⅳ和Ⅰ类水;而根据单因子评价方法,进水口和出水口水质均属于Ⅴ类,主要是由于化学需氧量超标导致。模糊数学评价法用隶属度来描绘模糊的水质分级界限,避免了传统水质分级不连续的缺陷,避免了在单因子评价中因某项参数超标而将水质定类的缺点,得到了较为客观的评价。Fuzzy evaluation method was adopted to assess the water quality of inflow and outflow of Jinan Yellow River reser- voir. The evaluation results show that the inflow and outflow belong to category I and IV, respectively. According to single factor evaluation method, the inflow and outflow water quality belong to category V, which is mainly caused by excessive chemical oxy- gen demand. Fuzzy evaluation method can be used to describe the fuzzy membership degree of water quality classification bounda- ries, avoiding the defects of traditional and single - parameter indicator water quality assessment methods.
