Research on City Image Logo Design Methods and Communication Strategies Based on Pierce Semiotics

Based on Pierce's semiotic theory, this study systematically explores the methodological path of urban image logo design. Through an in-depth analysis of the basic theories of Pierce's semiotics, Pierce's symbolic trichotomy, ternary communication model and ternary composition theory are synthesized and applied to the design methodology of urban image signs. This interdisciplinary methodology aims to enhance the effectiveness of urban image logo design and its communication power among the public. The study constructs an innovative framework for city image logo design from the three key dimensions of semiotics: internal logic, meaning transformation and communication cycle. The framework not only explains the application mechanism of Pierce's semiotic theory in urban image logo design, but also proposes a set of scientific and rigorous design methods and communication strategies, which not only has important theoretical value, but also has a guiding significance for the practical activities of urban image logo design.
