Urban typhoon risk assessment is important in urban disaster prevention and insurance assessment. Most of the existing studies on urban typhoon risk assessment systems build assessment models from a subjective perspective. In contrast, few studies mine information from existing historical data and build assessment models from it. In this study, a set of urban typhoon risk assessment systems was constructed by combining the improved CRITIC method and TOPSIS with 11 correlation indicators, including average daily rainfall and river network density, in the areas under the jurisdiction of Wenzhou City, Zhejiang Province. This system was used to evaluate the risk index of each region in Wenzhou, and the proportions of high risk, medium risk, and low risk were obtained as 26.14%, 41.25%, and 18.65%, respectively. This study constructs the model from both subjective and objective aspects, thus providing a reference for urban typhoon risk assessment and prevention.
