摘要
考虑到TOPSIS法在进行综合评价时的不足之处,提出了运用垂直距离来代替欧氏距离进行水质综合评价,并引入信息熵来计算各评价指标的权重以避免权重确定的主观性,建立了基于熵权的改进TOPSIS水质评价模型.结合邯郸市地下水水质评价进行了应用,表明其计算简便,思路清晰,结果令人满意,适合于水质评价.
According to the deficiency of TOPSIS method in the comprehensive evaluating, this paper replaced Euclid distance with vertical distance, introduced information entropy to work out coefficient of evaluating indexes so as to avoid the subjectivity of calculating coefficient of weight, and built up improved TOPSIS model based on coefficient of entropy to evaluating water quality. The model was used to evaluate water quality in Handan city. Results show that the method is simple, and is feasible to evaluate water quality.
