This paper uses the analytic hierarchy process (AHP) as the basic framework, and evaluates the water environment risk management technology of the river basin in Liaoning Province, so as to scientifically and reasonably measure the advantages and disadvantages of the existing technology.The research results show that the best technical indicator is the research management technology of water environment quality monitoring technology; the best environmental indicator is the management technology of the research project of water quality safety assessment and early warning management technology in the basin. The highest overall score is the water environment quality monitoring technology method research management technology. Each management technology has certain advantages, and the management technology should be used jointly.
