Abstract: An evaluation index system of urban water resource vulnerability was constructed to objectively reflect the sustainable development capacity of water resources and provide reference for the construction of sustainable development cities. The improved analytic hierarchy process and entropy weight method were adopted to determine the combined index weights to achieve a unification of subjectivity and objectivity and make the calculation more accurate and reliable. A comprehensive evaluation method was used to build the water resource vulnerability evaluation model. The annual water resource vulnerability index and vulnerability grade were calculated and determined. The results showed that the water resource vulnerability index of Jinan showed a fluctuant trend from 2008 to 2017. The annual vulnerability grade was severe, moderate, or mild vulnerability, and there was a gradual reduction in vulnerability overall, which was consistent with the actual situation. In the future, the water resource vulnerability grade will be reduced if the industrial structure can be further reformed and optimized, and the level of water resource management and the utilization efficiency of water resources can be further improved by strengthening the construction of smart water systems.
