摘　　要：为了合理地评价河流水质,在集对分析原理的基础上,建立了基于熵权的六元联系数水质评价模型,该模型将联系分量系数作为标记,并根据水质指标与标准限值的联系程度对联系分量赋值。用该模型对小清河9个主要河段的10项水质指标进行分析。结果表明,六元联系数法理论严谨,计算简便,评价结果更能真实反映水质状况,是一种有效的水质综合评价方法。In order to objectively evaluate the water quality of the river,the six-element connection number model based on entropy weight was developed on the basis of SPA.The model made the related-component coefficients as a mark,and the related components were valued according to the connection between the water quality indexes and the water quality standard.The application of the model to assess 10 evaluating indicators of the 9 main reaches of Xiaoqing River has led to the evaluation results of every reach.The results showed that the six-element connection number model is reasonable and handy,and the results could accurately reflect the actual condition.It was prove to be a convenient and effective method for water quality assessment.
