德惠市第三水源地水质熵权属性识别评价

Identification and evaluation of entropy weight attribute of water quality in the third water source of Dehui City

在德惠市第三水源地开展了地下水基础环境状况调查的基础上,为保证饮水安全,以地下水监测数据为依据,建立了该区地下水水质评价指标体系,制定了评价基准,采用熵权属性识别模型进行了地下水水质综合评价。该模型通过评价样本信息确定熵权,避免了权重确定的主观偏差,简单易懂,评价结果可靠。

On the basis of groundwater environmental condition investigation of the third water source of Dehui City, in order to ensure the drinking water safety, an assessment of the water quality was done. Based on the monitoring data, a groundwater quality assessment system has been set up with criteria designed. Attribute recognition model based on coefficient of entropy has been finished to evaluate groundwater quality. The results show that it is suitable to evaluate water quality with reasonable conclusion and simple calculation, which designed the value by the actual samples and avoid the subjective deviation of the weight value.
