Landscape Beauty Evaluation And Design Of Metro Transfer Station From The Perspective Of Public Perception

In recent years,the integrated construction of urban rail transit has been carried out in major cities,and the construction of subway has entered a stage of rapid development,but it is followed by the appearance of subway interchange station entrance landscape design that is not harmonious with the development of the surrounding environment.Therefore,in order to solve the current problem of the difference between the design of the entrance and exit landscape of the subway transfer station and the public aesthetic demand,this paper,on the premise of satisfying the traffic function,improves the overall image of the entrance and exit of the subway transfer station and the surrounding space based on the public aesthetic perception and evaluation.First of all,relevant research status at home and abroad was summarized to form a clear research framework,related concepts and theories were sorted out and explored,and a landscape beauty evaluation system for the entrance and exit of subway transfer station was constructed,which was integrated by BIB-LCJ method,SD method and principal factor analysis method.Secondly,the 25 selected samples of entrances and exits of Xi ’an subway transfer stations are evaluated to explore the public’s aesthetic preference.According to the evaluation data,a regression model was established to obtain the ranking of the influence degree of the landscape beauty perception evaluation factors at the entrance and exit of the subway transfer station,including 11 factors such as landscape color coordination,spatial scale coordination,plant configuration level,plant color richness and view line order.And the 11 factors from the color elements,form elements,spatial scale elements,spatial sequence elements and cognitive elements of five aspects of the problem analysis.Based on the analysis of the problems,corresponding design strategies for improving beauty degree are proposed: to create coordinated and comfortable landscape colors at the entrances and exits of subway transfer stations,to create diversified and beautiful landscape forms at the entrances and exits of subway transfer stations,to create appropriate spatial scales at the entrances and exits of subway transfer stations,to improve the order of viewing lines to reflect the beauty of artistic conception,and to pay attention to the presentation of the connotation and beauty of the entrances and exits of subway transfer stations.Finally,the design theory is applied to the landscape optimization design of the entrance and exit of the North Street section of Xi ’an Metro Line 2,aiming to solve the problem and design the entrance and exit space of the subway transfer station in line with the aesthetic needs of the public.The results show that the application of beauty evaluation system at the beginning of the design can greatly improve the difference between landscape design and public aesthetic needs.The enhancement of the beauty degree of the entrance and exit landscape of the subway transfer station can not only make the entrance and exit of the subway better integrated into the urban landscape,but also provide the public with beautiful,comfortable and experiential landscape space.
