This paper takes Dalian Port as a starting point to explore evaluation ideas and optimization plans for port resilience. Based on a review of existing literature and on-site investigations, an evaluation system is constructed from four perspectives: infrastructure, operation and management, low-altitude economy, and sustainable development. The Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE) methods are employed to comprehensively assess the overall resilience level of Dalian Port. The calculation results indicate that Dalian Port has significant advantages in infrastructure, stable operation and management, and sustainable development, but lags relatively behind in the development of the low-altitude economy. Based on the current issues, specific suggestions are proposed in the paper: continuously strengthening infrastructure construction, improving operation and management mechanisms, promoting the deep integration of the low-altitude economy with the port, and continuously implementing green development plans, etc. The conclusions drawn from this analysis can provide certain reference value for Dalian Port and other ports to enhance their resilience through the low-altitude economy.
