摘要
考虑到传统地下水水质模糊综合评价中权重确定的不确定性和主观性,结合各指标所提供的信息量,将信息熵理论引入到指标权重的确定中,评价石家庄地区典型地下水水质,并与传统的模糊综合评判方法的评价结果进行对比分析,结果表明,基于熵权的评价结果与传统模糊综合评价结果相似,能够反映水质的特征,由此可见信息熵理论可以用于地下水水质评价中权重的确定。
Considering the uncertainty and subjectivity of weight determination in the traditional groundwater quality fuzzy synthetical evaluation,a new method to definite the weight based on entropy theory is introduced into the groundwater quality evaluation of Shijiazhuang City,and a contrast study between the new entropy weights based the new method and the traditional method is conducted.The results show that the evaluation results based on the new method are similar to that based on traditional method and the new entropy theory could be effectively used in the groundwater quality evaluation.
