通过提高黄河兰州段的水环境质量评价的条件,倒逼黄河上游提高水环境的治理

By improving the water environment quality evaluation conditions of the Lanzhou section of the Yellow River, the upper reaches of the Yellow River are forced to improve the governance and management of the water environment. This article takes the dissolved oxygen and other water quality indicators of the water quality monitoring section of the Yellow River Lanzhou section as the research object, and uses the actual measured data in 2018 as the research object. Basically, first evaluate the water quality of each monitoring section, and then use the fuzzy cluster analysis method to cluster and classify each monitoring section. The results show that: the water quality of each section is good; according to the actual situation, it is reasonable to classify the Fuhe Bridge and Xincheng Bridge sections into one category, and it is more reasonable to classify the remaining sections into one category. The surface water classification standards for the Huangshui Bridge and Minhe Bridge sections are implemented Increased from category IV to category III.

By improving the conditions for water environmental quality evaluation in the Lanzhou section of the Yellow River and forcing the upper reaches of the Yellow River to improve the management and management of the water environment, this paper takes the water quality index such as dissolved oxygen in the water quality monitoring section of the Lanzhou section of the Yellow River as the research object, and, based on the 2018 measured data, evaluates the water quality of each monitoring section first, and then uses fuzzy clustering analysis methods to cluster each monitoring section. The results show that the water quality of each section is good, according to the actual situation, the section of the Fuhe Bridge and the New town bridge is classified into one category, and the rest of the section is classified into a more reasonable category, that is, the surface water classification standard implemented by the Sushui Bridge and the people and the bridge section is raised from class IV to class III.
