摘　　要：采用单因子评价法、综合水质标识指数法、灰色聚类法三种水质分析方法 ,对2022年1月~12月嘉陵江汉中段主干断面水质状况进行分析。根据三种分析方法的评价结果 ,对比分析可得:单因子评价法,简单易行,并且对评价结果要求更严格;综合水质标识指数法更适用于污染程度大的水质分析;灰色聚类法适用于同一水质类别的水质状况优劣程度的对比分析。The water quality of the main section of the Hanzhong section of Jialing River from January to December 2022 was analyzed by using three water quality analysis methods:single factor evaluation method,comprehensive water quality identification index method and grey clustering method.According to the evaluation results of the three analysis methods,comparative analysis can be concluded:the single-factor evaluation method is simple and easy to implement,and has stricter requirements for evaluation results;the comprehensive water quality labeling index method is more suitable for water quality analysis with high pollution levels;the gray clustering method is suitable for comparative analysis of the quality of water quality in the same water quality category.
