Suitable Design Guidelines of City Tourism Site for Public Service: Optimization Design of Marina in Tianjin, China

As urbanization accelerates in developing countries and populations continue to grow, the demand for sustainable urban regeneration becomes increasingly urgent. This study explores how urban regeneration can be integrated with tourism development to promote sustainable and inclusive growth. Using the theory of organic regeneration, this study emphasizes the role of localized, small-scale interventions that enhance the urban environment while boosting tourism appeal. Through field research at the Tianjin Cruise Terminal, this study applies the KANO model to classify user needs and prioritize design interventions based on the needs of various user groups, including tourists, exercisers, anglers, and local residents. By analyzing user group activity frequencies, the study identifies Must-be, One-dimensional, and Attractive needs, and utilizes weight analysis to assess the impacts of different facilities on user satisfaction. This approach ensures that the design guidelines effectively address both essential and value-enhancing features. The findings provide more suitable design guidelines for improving tourism infrastructure, promoting sustainable development, and enhancing the overall urban experience.
