摘要
地下水源地的水质评价不仅可以促进水资源合理开发利用,也对制定地下水资源的保护决策有很好的指导意义。本文利用Shannon熵理论客观地确定出水质评价指标的熵权系数,并结合程乾生提出的属性识别理论建立了基于熵权的地下水源地水质属性识别模型。该模型和作者应用SPA模型的评价结果具有很好的一致性。
Evaluation of water quality for groundwater sources can promote rational development and utilization of water sources, and also play a good guiding role in decision making for groundwater resources protection. This paper established the attribute recognition model of water quality for groundwater sources based on entropy weight by Chen Qiansheng＇ s attribute recognition theory. Entropic coefficients of water quality assessment indicators were determined by using Shannon entropy theory. The results of this model and the SPA model show good consistency.
