To establish a resilience evaluation index system of water affairs in Beijing based on AHP and entropy weight methods

With accelerated urbanization and climate changes, a new paradigm of urban security development is to establish resilient cities． As important infrastructure in the construction of resilient cities, water affairs play an increasingly important role in disaster prevention and reduction． An evaluation framework is constructed based on the definition of water resilience． On-site investigation, expert consultation and other methods are used to establish the Beijing urban water resilience evaluation index system (with 15 indicators, including target layer, criterion layer and index layer), to comprehensively reflect the water resilience status． AHP and entropy weight methods are used to calculate the comprehensive weight for evaluation of Beijing water resilience． These data show that current evaluation score of water resilience in 2022 is 88.04, and the resilience level will increase year by year until 2025, consistent with the overall evaluation trend． Suggestions are made to further improve the water resilience． This work will provide decision-making reference for planning and construction of resilient city in Beijing．
