| 摘 要： | 为避免地下水水质评价中对各指标权重的主观性判断,采用熵权理论确定了水质评价指标的权重系数,并结合属性识别法,选取4个主要影响因素作为评价指标,建立了台兰河灌区地下水水质属性识别模型。结果表明,灌区地下水水质评价结果与实际水质情况相符,可见熵权属性识别法可充分反映地下水水质评价中各数据样本的信息,降低了主观因素的影响。

| Abstract: | In order to avoid the subjective judgment on the weight of each index, the entropy theory is adopted to determine the weight coefficients of the water quality evaluation. Combined with the attribute recognition method, four main factors are selected as the evaluation index. And then, it establishes the groundwater quality attribute recognition model of the Tailan River irrigation area. The evaluation result is consistent with the actual situation. The results show that this method can fully reflect the information of each sample data and reduce the influence of the subjective factors. |
