摘　　要：以燕山水库水质评价为例,针对水质等级的相对模糊性及单项指标评价结果的不相容性问题,基于模糊物元理论,构建了采用三标度法确定权重、将模糊物元分析与欧氏贴近度相结合的水库水质评价模型,并与其他方法进行比较。实例结果表明,评价结果与实际情况相吻合。In view of the fuzzy characteristics of water quality grade and the non-consistency characteristics of evaluation result for single index,the model of evaluating water quality of reservoir is established by using three-mark method to determination of weights and combining matter-element with Euclid approach degree.The model is applied to evaluate water quality of YanShan reservoir.Compared with other methods,the results are accord with practical situation.
