Abstract
Groundwater quality evaluation is the basis for groundwater pollution prevention and control and rational development and utilization.In order to solve the limitations of the"single indicator highest category method"that may exaggerate the degree of water quality,fail to reflect the overall condition of water quality,and fail to distinguish the quality of water within the same category,the fuzzy Borda method was used to combine and evaluate the water quality evaluation results of the comprehensive pollution index method and the principal component analysis method of four groundwater sources in Jinan.The results show that all three evaluation methods can reflect the overall condition of water quality and distinguish the quality of water in the same category,and the results are consistent.The fuzzy Borda combination method can effectively avoid the influence of weight assignment on the evaluation results,has a higher degree of discrimination,and is more reasonable and practical in the water quality evaluation of drinking water sources.关键词
