| 摘 要： | 水质评价中各单指标的评价结果具有独立性和不相容性，需要综合考虑各指标的属性。通过将熵值法与属性识别模型相结合，建立了基于熵权的属性识别模型，应用一种新方法进行地下水水质综合评价，它运用熵值法来确定权重系数，能够避免权重确定的主观性问题。结合实际应用表明其可以有效地解决水质的优劣评价问题，且结果合理，计算简单。

| Abstract: | Because of independence and incompatibility resulted from outcomes of single index in course of evaluating water quality, it is necessary to take into account synthetically the attribute of every index.By combine the entropy value theory and attribute recognition model together, attribute recognition model based on coefficient of entropy is set up and applied to evaluating groundwater quality by the new method, coefficient of weight calculated with law of entropy value is exercised the problem of calculating coefficient of weight subjectively. The outcome from concrete application indicates that it is suitable to evaluate water quality with reasonable conclusion and simple calculation. |
