Groundwater Environmental Quality Evaluation Based on the Entropy Weight Method

摘要：

　　Eight kinds of typical pollutants were selected as evaluation factors to determine the weight of water quality evaluation index based on the Entropy weight method.Used the improved Matter-element extension model and Nemerow index method,combined groundwater quality standards (GB/T14848-93),the groundwater quality of 14 groundwater samples in Guqiao mine in Huainan was evaluated.Results of the two methods were consistent,and showed that the water qualities of the upper and central aquifers of Cenozoic were better.While the water qualities of the bottom aquifer,coal measures aquifer and the limestone aquifer were worse.And the results reflected the overall situation of groundwater quality objectively.
