Abstract：Water security is an important component of national security,relating to resource security,ecological security,economic security,and social security.Evaluating Beijing's water security in the new era,summarizing existing problems,and proposing countermeasures is of significant guidance for improving the city's water security assurance.This paper establishes a comprehensive water security assessment indicator system for Beijing based on the"natural-social"dual water cycle,and uses a model of water security degree calculation combining single-indicator quantification,multi-indicator synthesis,and multi-criteria aggregation to evaluate Beijing's water security from 2012 to 2022.The results indicate that the water security index of Beijing steadily increased during 2012-2022,with the water security situation improving year by year.The water security degree improved from a basically safe level in 2012 to a relatively safe level in 2016,and further reached a safe level in 2021.Based on the assessment results and projections for future water security,this paper proposes countermeasures for water security in Beijing,aiming to provide reference and guidance for research on the city's water security assurance.
