| Abstract: |
| 【Objective】Analyze and evaluate river water quality, and provide basis for improving and protecting river water environment quality【Method】The water quality monitoring data of three sections of Xiao River, Tang River and Anyang River from July to December in 2020 were selected to evaluate and analyze the water quality of the analysis model and matter element analysis model by using entropy weight set.【Result】The monthly variation of water quality in the three rivers is closely related to the surface runoff caused by precipitation.Among them, the water quality of Xiao River fluctuated between Ⅲ- Ⅳ from July to November, and the water quality was good in December, reached the standard ofⅠ.In July, November and December, the water quality of Tang River wasⅠ, in August and September, the water quality was Ⅲ, and in October, the water quality wasⅡ.The water quality of Anyang River from July to December wasⅠ.【Conclusion】For rivers with water quality between Ⅳ-Ⅴclass ,the evaluation result of fuzzy clustering association degree in the set pair analysis model is more reliable than that of fuzzy association degree, and the set pair analysis model is easy to calculate, which is close to the results of other comprehensive evaluation methods for water quality. It can provide a reliable basis for the management of water resources protection in the future. |
