Research On The Method Of Building Layout Generation Based On The Evaluation Of Urban Spacial Perception

China’s urban development has entered the stage of stock development,and the demand for improving urban space quality is increasing day by day.As an image activity of "designing cities",urban design is considered to be one of the effective means to solve urban problems,create and improve urban spaces.Compared with the urban design view that only focuses on the form of the physical environment,the humanistic urban design view takes the behavior and psychological needs of space users as the starting point of environment shaping,which is an effective way to improve the quality of urban space.The classic research methods of environmental behavior have made important contributions to the study of the complex interaction between the artificial environment and users.With the expansion of the city and the speed of development,the limitations of these classic analytical methods have become increasingly prominent.New technologies,represented by spatial syntax analysis,machine learning,virtual reality technology,etc.provide many new methods for quantitative analysis of the subjective evaluation of people’s perception of urban space.However,these new technologies currently mainly play a role in academic research,which is still out of touch with urban design practice.Various spatial configuration analysis methods based on spatial syntax theory are relatively widely used in design practice,and there are already many mature analysis tools to choose from.However,most of these tools have the problem of cross-platform use,which can only be used for post-evaluation of the design scheme,and cannot be used for real-time update and automatic optimization of the scheme according to the evaluation results.These obstacles make the value of spatial perception analysis not fully utilized in practice.Therefore,this study intended to make architectural layout problems in urban design as the research object,the computer generated design method combined with people’s perception of space analysis algorithm,attempt to put forward a kind of architectural layout generation method based on urban space perception evaluation,and on the Grasshopper platform to develop the corresponding design tool,hope to be able to play a role in the concept phase of urban design,the improvement of power quality of urban design.
