This paper takes the design of the "Fenghe Fuwa" IP image as the research object, based on the traditional autumn harvest culture connotation, combined with modern design concepts and digital technology, to construct a mascot IP that is both cultural, ornamental and commercially valuable. By sorting out the core elements of traditional rural culture and contemporary communication demands, the research clarifies the character background and design positioning of "Fenghe Fuwa", completes the IP image design from dimensions such as image modeling, color matching, and visual symbols, and expands the contents such as poster design, application scenarios, and derivative product development. Ultimately, a complete IP image system and operation plan will be formed, providing a practical path for the innovative inheritance of traditional agricultural culture, while injecting new impetus into rural tourism and agricultural product promotion, achieving the coordinated development of cultural and economic values.
