Comprehensive analysis of water quality in Hanzhong monitoring section of Hanjiang River by weighted Euclidean distance method
According to the evaluation standard of'surface water environmental quality standard'(GB 3838-2002),the class I water quality standard is selected as the origin,and the weight of each rating factor is obtained by using the coefficient of variation method.The variable weight Euclidean distance of the factors to be evaluated is calculated,and the space of water environment quality evaluation is established.The weighted Euclidean distance between the monitoring results of water quality section and the water quality evaluation standard in Hanzhong from January to December 2023 is compared and analyzed,so as to determine the water quality level.The purpose of this paper is to explore the application of weighted Euclidean distance method in surface water quality analysis.The water quality level was evaluated by the weighted Euclidean distance method,and the water quality status generally showed a preference trend.
