| 2021年6—9月对沱沱河流域的6条主要河流布设6个监测点，监测23项水质指标并作评价，结果显示，10项指标检出，13项指标未检出，水质基本优于地表水Ⅱ类。根据水质监测数据，采用主成分分析和相关分析法建立评价因子集，基于博弈论对熵权法和改进的层次分析法确定的指标权重进行优化组合，构建博弈理论组合赋权的水质模糊评价模型进行水质评价，运用综合评判指数量化水质等级。结果表明，流域内高锰酸盐指数（IMn）、五日生化需氧量（BOD5）、总磷（TP）、氨氮（NH3 N）等指标是水质主要影响因子，2021年6—9月沱沱河流域水质良好，6条河流水质的模糊综合评价结果均在Ⅰ～Ⅱ类之间。 |

| From June to September 2021， six monitoring sites were set up on six major rivers in Tuotuo River basin， and 23 water quality indicators were monitored and evaluated. Results showed that 10 indicators were detectable， and 13 indicators were undetected. The water quality was basically better than Class Ⅱ quality standards for surface water. According to water quality monitoring data， principal component analysis and correlation analysis were used to establish an evaluate factor subset.Based on game theory， the indicator weights determined by entropy weight method and improved analytic hierarchy process were optimized and combined. The water quality was evaluated by constructing a 〖GK!86mm〗fuzzy water quality evaluation model based on game theory combination weighting， and graded bycomprehensive evaluation index. The results showed that permanganate index（IMn）， five day biochemical oxygen demand（BOD5）， total phosphorus（TP） and ammonia nitrogen（NH3 N） were the main influencing factors. From June to September 2021， the water quality of Tuotuo River basin was good， and the fuzzy comprehensive evaluation results of the six rivers were all between Class Ⅰ and Class Ⅱ quality standards for surface water. |
