| 摘要: |
| 【目的】分析评价河流水质状况，为改善和保护河流的水环境质量提供依据。【方法】选取2020年7-12月硝河、汤河、安阳河3个断面的水质监测数据，采用熵权集对分析模型和物元分析模型进行水质评价与分析。【结果】三条河流的水质月际变化与降水产生的地表径流关系密切。其中，硝河7-11月水质在Ⅲ-Ⅳ之间波动，12月份水质较好，达到Ⅰ类水的标准；汤河在7月、11月和12月水质均为Ⅰ类，8月与9月水质为Ⅲ类，10月水质则为Ⅱ类；安阳河7-12月水质均为Ⅰ类。【结论】对于水质介于Ⅳ-Ⅴ类之间的河流，集对分析模型中模糊聚类联系度的评价结果相较于模糊联系度要更为可靠，且集对分析模型计算简便，与其他水质综合评价方法的结果较为接近，可为今后水资源保护的管理工作提供可靠依据。 |

| 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. |
