Research On Evaluation And Optimal Design Of Digital Landscape In Urban Open Space

Urban open space as an important carrier of various activities of urban residents,its spatial form and function have been changing.In order to meet the growing needs of the public for a better life,how to use new technologies to update and optimize the landscape in urban open space and complete the digital transformation of landscape is a new challenge in the process of urban open space landscape construction War.This paper studies this problem and the results are as follows(1)Taking the digital landscape in urban open space as the research object,through case summary and field research,this paper classifies the current digital landscape applications in urban open space,lists the landscape entities of corresponding landscape types,and summarizes the landscape demand and digital development trend of urban open space under the background of Internet era.(2)Based on the principal component analysis and factor analysis,this paper constructs a comprehensive evaluation system of urban open space digital landscape,comprehensively evaluates the urban open space digital landscape from four evaluation levels of building facade landscape,multimedia landscape,water landscape and landscape facilities,and determines the evaluation factors and evaluation standards of the corresponding evaluation level.Taking the open space of Qianjiang New City in Hangzhou as an example,this paper makes a comprehensive evaluation of digital landscape,determines the existing digital landscape comprehensive evaluation grade and the importance of evaluation index,and obtains the current digital landscape comprehensive evaluation grade F = 3.709,which indicates that the overall landscape benefit is good,and determines the digital landscape satisfaction evaluation grade of each open space of Qianjiang new city,It provides a theoretical basis for landscape optimization design.(3)Through theoretical research and investigation,combined with public feedback,this paper summarizes the construction needs of urban open space digital landscape under the background of the times,puts forward the corresponding landscape design guidelines,and puts forward the corresponding landscape optimization design methods from four aspects of lighting landscape,multimedia landscape,water landscape and landscape facilities.Taking the open space in the core area of Qianjiang New Town in Hangzhou as an example,the public feedback on the existing digital landscape in the site was obtained by means of questionnaire survey,free interview and actual participatory survey.Based on the comprehensive evaluation results of the digital landscape in the previous paper,combined with the current situation of the open space and the user’s behavior mode,the optimization ways were put forward,including multimedia landscape optimization,humanistic connotation optimization and waterscape perception Optimization,building optimization and service facilities optimization.
