苏州作为江南地区重要的历史文化名城，虽然从1986年开始便指定了古城的

Suzhou, as an important historical and cultural city in the south of the Yangtze River, has designated the protection plan of the ancient city since 1986, but in the later urban construction process, the city skyline was also too high and too high due to demolition and construction. The scale, color, material and shape of the building facade are too cluttered, which leads to the lack of urban regional characteristics and pleasantness. Therefore, this paper takes the old city of Suzhou as an example, from the perspective of visual perception and tactile perception, to study the urban façade's skyline, the tactility of materials, the visual impression of colors, and the visual aesthetics of architectural forms. Based on this, we discuss the method of Reinvention of the regional characteristics of urban facades, in order to improve the convergence of urban facade images and the loss of regional characteristics in historical cities, enhance the recognizability of the city, and enhance the residents' sense of belonging and urban memory.

As an important historical and cultural city in the south of the Yangtze River, Suzhou has designated the protection planning of the ancient city since 1986, but in the later process of urban construction, the height of the urban skyline is too high and the building facade scale, color, materials and shape are too messy due to large-scale demolition and construction, resulting in the lack of urban regional characteristics and amenity. Therefore, taking the old urban area of Suzhou as an example, from the perspective of visual perception and tactile perception, this paper studies the skyline marginal contour of the urban facade, the touchability of materials, the visual impression of color and the visual aesthetics of architectural form, and discusses the method of reinvention of the regional characteristics of the urban facade on this basis, in order to improve the assimilation of the urban facade image of historical cities, The loss of regional features and other issues will enhance the identifiability of the city and enhance residents' sense of belonging and urban memory.

Suzhou, as an important historical and cultural city in the south of the Yangtze River, has designated the protection plan of the ancient city since 1986. However, in the later period of urban construction, the problems of too high skyline, too messy scale of building facade, colors, materials and shapes also resulted in the lack of urban regional characteristics and amenity. Therefore, taking the old city of Suzhou as an example, this paper studies the skyline marginal outline, the touchability of materials, the visual impression of colors, the visual aesthetics of architectural forms and other contents of the city facade from the perspective of visual perception and tactile perception, and based on this, discusses the method of Reinvention of the regional characteristics of the city facade, with a view to improving the problems of the image convergence of the city facade and the loss of regional characteristics of historical cities, enhancing the identifiability of cities, and enhancing the sense of belonging and urban memory of residents.
