Regional Matrix-based Urban Design Study

Economic globalization and the information technology integration have brought internationalization of city culture and assimilation of city space and figure, which lead to "culture crisis" , "characteristic crisis" and "consciousness crisis" in the city. Facing to this confusion, city planners and city designers are always researching: which style can the city be?The overall city design is between the overall city planning and concrete streets design.Based on the theory of the relationship between city and region, the character of city comes from the breeding and heritage of the region; based on bio-landscape theory, characteristic of city comes from permeation of the region. The basic conditions of the region roots in the figure of the city physical space.There is a direct or indirect exchange relationship among visual -matrix and abstract-matrix and image element of the city. The physical elements that make up the city are visual expression of the invisible elements, such as the natural-condition, developing mechanism, history process, and custom in cities and regions. There is an implicit and exchange relationship between region' s background and the physical elements.Urban design process that bases on the basic condition of region is a exchange process of the basic condition of region and the figure of the city physical space. Then, operation modal and it's structure of urban design have taken on a new running condition, including the overall idea of urban design, environmental design of the city social culture and city figure.This paper introduces the connotation of city design, developing process and tendency of city design idea. Secondly, it researches the structure model of city design, which bases on the geography theory about the relationship between city and region, and patch-corridor-matrix model of bio-landscape. It provides theoretical support for the practice research in the third sector.From the practical analysis of the city design, this paper discuses the overall city design of JiAn City, JiLin province, and brings up the overall idea, the environmental design of city social culture and city figure for JiAn City, and provide suggestion for it' s city characteristic.Author brings up the overall structure and the operation model of city design in the view of the city background, and analysis JiAn City' s background comprehensively and objectively, and provides countermeasure and suggestion for the JiAn City' s characteristic construction. So it has significant practicality.
