Abstract
Taking some water quality sections of Chuhe River as the research object,comparing the application of single factor evaluation method and fuzzy mathematical evaluation method in water quality evaluation.The single factor evaluation method evaluates the water quality categories of three sections as ClassⅣ,ClassⅣand ClassⅤ,respectively;The fuzzy mathematical evaluation method synthesizes multiple evaluation factors through membership functions,and the results show that the water quality categories of the three sections are Class Ⅲ,Class Ⅲ and Class Ⅳ,respectively,which is more scientific and objective.Research has shown that the fuzzy mathematical evaluation method can effectively address the fuzziness and uncertainty of evaluation factors,avoiding the one sidedness caused by a single factor exceeding the standard.However,it has shortcomings such as strong subjectivity in selecting evaluation factors and complex calculation processes.In the future,the weight determination method should be optimized,the calculation process should be simplified,and the advantages of the two methods should be combined to improve the scientific and practical nature of water quality evaluation.关键词
