Study of surface water quality characteristics based on principal component analysis and cluster analysis
The surface water quality characteristics of Wuzhou city in 2022 were analyzed by combining principal component analysis with cluster analysis.The results of analysis show that the surface water quality of Wuzhou was good in 2022,and was mainly affected by two principal components of organic pollution and eutrophication index,metal index.According to the pollution characteristics,the surface water in Wuzhou is divided into three groups.Compared with the single factor evaluation method,the combination of principal component analysis and cluster analysis can reflect the water pollution situation and pollution factors more scientifically and reasonably,and pro-vide a more scientific basis for water environment protection and management.
