Fuzzy Design Methods In The Design Of Urban Image

City image design is a comprehensive subject referring to multi-fields. It has showed academic and realistic significance in globalization and city-progress. Coordination in various subjects plays an important role in design nowadays. From construction to plane figure, from art to production, from inner room to clothes, all things above is gradually coming into integration of design results. City image is the most complicated among these systems. Traditional linear logical design is limited to some extent in such complex system. The single linear developing pattern confines its adaptability and variation in many fields. This paper analyzes the core of fuzzy design and the way of operation in traditional design in order to get variously possible ways of operation in ambiguity design. Besides, the papers further analyzes operation of ambiguity design in practice and try to use this operation in city image design and do some foresight nasalization in the possible results. It is hoped that ambiguity design will play as catalyzed in the professional improvement of the subject of city image.
