Abstract: In water quality monitoring, the characteristic analysis and evaluation of water quality are of great significance. To overcome the limitations of the water quality index evaluation method, which are difficult to accurately and comprehensively reflect the comprehensive status of water quality, machine learning has been introduced in recent years and has been more and more widely used in the indicator prediction and evaluation of water quality. Machine learning provides a more scientific and efficient means for water quality evaluation by integrating multi-source and multi-index water data and mining the complex linear or nonlinear relationship between water quality factors and water quality.
