Research On The Evaluation And Optimization Design Of Campus Green Space Landscape Based On Security Perception

The knowledge economy era promotes the society to pay more and more attention to the campus construction,the campus green space as an important part of the educational environment,exerts multiple functions,its planning and design also receives much attention.But the campus green space design and construction pays attention to the landscape construction and the ecological benefit exertion,lacks to use the group psychological behavior research.Through investigation and observation,it is found that individual activities in different situations will produce different degrees of safety concerns,and the level of security affects the utilization rate of the site,resulting in site wasteland.At the same time,with the development trend of campus space socialization,the campus environment is becoming more and more complex,which exacerbates the users’ own safety psychological worries.In this paper,environmental psychology,environmental behavior and landscape gardening are integrated,based on the perspective of safety perception,from the university campus green space specific users(university students)this group,campus green landscape in-depth discussion,including the following aspects:(1)The definition of the concept of safety perception and the induction of influencing factors.By reading the literature,"safety perception" is defined as whether students have a sense of control,a sense of determination,and a psychological state of risk when they are active on campus green space.And according to the frequency of the occurrence of the research literature,the influencing factors were summarized into 26 specific evaluation factors.(2)The construction of the safety perception evaluation system for the main user of campus green space.First of all,through field research,research and analysis of campus green space subject user psychological security needs and security under the influence of landscape preference,from the overall space,landscape elements,safety management,maintenance management,social factors,personal factors six levels,to build the campus green space subject user safety perception evaluation system.The index layer factors in the framework system are selected to determine the 23 evaluation factors through screening,the indicators are compared with two,AHP(Analytic Hierarchy Process),and the weight value of the evaluation index is finally determined.(3)Empirical research.Based on AHP-FCE(level analysis method-fuzzy comprehensive evaluation),through the comparative analysis of landscape types,six representative different landscape feature situ locations in Hunan Agricultural University were selected as empirical research objects.Through questionnaire survey,combined with the fuzzy comprehensive evaluation method of the evaluation of various indicators,the user’s sense of security score in each location is calculated.The evaluation results are analyzed in detail,and the design of the transformation is optimized for the less secure places.(4)Based on safety awareness,the strategy of green space landscape optimization on university campuses is proposed.Combined with the research results and evaluation system weight,from the use of landscape elements,improve spatial form and improve the management system three aspects of the proposal,to build a defensive material space,create a defensive environment atmosphere,improve defensive security measures,multi-proll,multi-strategy and use,to build to meet the psychological security of college students campus green landscape,to create a "peaceful campus" in the future to provide guidance and reference role.
