In this paper,fuzzy comprehensive evaluation based on the application of AHP and entropy weight method to obtain quadratic combina-tion weight of each index method,the study area four dry season water quality monitoring sections were evaluated. The results show that this meth-od avoids the subjective expert score weighting method differences,good to meet target weight and the effective degree of credibility.%在模糊综合评价的基础上，应用层次分析法与熵权法二次组合获得各指标权重的方法，对研究区四个监测断面枯水期的水质进行评价，结果显示，采用该方法可以避免专家评分赋权法的主观差异，很好地满足指标权重的可信度和有效度。
