Evaluation Index System Of Campus Open Space That Affects College Students' Health In Cold Area

The continuous development of colleges and universities has brought about largescale campus construction,and the impact of campus environment on the health of college students has drawn more and more attention from the society.Relevant theoretical research has proved that built environment can affect individual health level through human behavior.Campus open space is the main area of college students' daily activities,so improving the quality of campus open space from the perspective of health plays an important role in promoting the health level of college students.Due to the special geographical location and climatic environment,the open space in the cold region also has some particularity.Therefore,it is of great significance to solve the health problems of college students in the cold region by studying the characteristics and relationship structure of the open space in the cold region and constructing the evaluation index system.This paper takes the health of college students as the starting point and the cold campus as the research object,and constructs the index system of campus open space.First of all,through to the related literature summary,the analysis of the influence of the environment for health intermediate medium,then using qualitative analysis method to analyze a large number of literature induction,cold preliminary selection of health can affect college students in the campus open space index factors,it is concluded that the destination accessibility,development density and strength of 25 primary index.Then,the focus group interview method was adopted to supplement and correct the indicators according to the particularity of campus and college students in the cold region,and 31 indicators were obtained after optimization.In addition,several rounds of expert questionnaires were used to determine the importance of the primary indicators,and the fuzzy field method based on the "double-triangle fuzzy number test" was used to screen the questionnaire results for statistical analysis.Finally,23 indicators of the cold campus open space that affect the health of college students were obtained.Then,the importance data of each index were collected through questionnaires for college students in the cold region,and the structure of the evaluation index system was constructed by using factor analysis in statistics.The structure is divided into three layers: target layer,criterion layer and index layer.The target level is college students' health;The criterion layer includes five elements: design mode,spatial function,landscape elements,public facilities,management and maintenance.The index layer includes 23 elements such as campus boundary design and management,line of sight design.Finally,Analytic Hierarchy Process(AHP)was applied to compare the importance of the evaluation indexes,and the indexes were weighted,so as to finally complete the construction of the evaluation index system of the cold campus open space that affects the health of college students.This article research results will provide a certain theoretical basis for the study of the related evaluation,to cold related strategy of campus open space,space planning and design,environmental construction and management to provide theoretical basis for study of the evaluation index system building method and corresponding process can and types of open space for other areas to evaluate research provides certain reference value.
