| At present,due to the continuous acceleration of urbanization in China,the urban renewal and street renovation of major cities are in full swing.As the main space interface to form the street public environment,street building facade is the key object of street renovation.The figure-ground relation of visual perception is a kind of theory which can reflect the visual characteristics of architecture and is widely used in various fields of architectural design.This paper attempts to analyze the visual form of the building facade by using the figure-ground relation of visual perception,and sums up the application and expansion of the relevant rules of the figure-ground relation in the building facade,so as to deal with the problem of the street facade encountered in the urban street governance.There are three parts in the core chapter.First of all,it is to sort out the guiding contents of the theory of visual perception,analyze the relevant concepts of the principle of visual perception,Gestalt psychology and the figure-ground relation of visual perception,as well as the application and expansion of the relevant laws in the design of building facade.Then it analyzes the problems and causes of the street facade in the current urban street renovation work,and determines the goal of the renovation work,that is,the integrity,continuity and identifiability of the street facade.Then the figure-ground relation of visual perception and its related rules are applied to the facade reconstruction of the street building,and the analysis of the integrity,continuity and recognizability of the street facade is carried out,as well as the specific application of the "figure background" rule and the completion organization rule in the facade reconstruction design of the street.Finally,the figure-ground relation of visual perception is applied to the actual case of Beijing Daxing Kangheyuan street facade reconstruction to verify the effectiveness of the figure-ground relation of visual perception in the facade reconstruction design of street buildings.It is found that through the application of the "figure background" principle and the "perfect organization" principle of the figure-ground relation of visual perception,the visual elements of the street facade can be analyzed and designed as a whole,which is beneficial to the improvement of the overall style of the street.Therefore,the theory of visual perception is a scientific and objective method in the facade reconstruction design of urban street buildings.It provides an effective and feasible analysis tool and reconstruction design method for solving the problems of the integrity,continuity and identifiability of the facade of urban street buildings,and puts forward a new idea for urban street renovation. |
