Abstract

The article intents to introduce a method by joining the improved Nemerow index method and the entropy weight that is used in groundwater quality evaluation. It should be noted that the entropy weight reflects the different influence of different pollutants. The authors take the northern water source of Yinchuan for an example and then calculate the weights of pollution factors by entropy, the results show that the improved Nemerow index method based on entropy weight can be more comprehensive and more objective to reflect the status of groundwater.
