寒地大学校园绿色空间在夏冬两季缓解学生焦虑的效能差异及其环境驱动机制OA

[Objective]This study aims to quantify the efficacy differences of green spaces on cold-region university campuses in alleviating student anxiety between summer and winter,and reveal the environmental driving mechanisms underlying the winter healing deficit,thereby transcending the single-season perspective orientation that assumes"the greener the better".[Method]Taking Dalian University of Technology as a case,seven typical types of outdoor spaces are selected in line with spatial morphology,vegetation composition,and functional differences.Panoramic environmental features are collected alongside on-site psychological experiments in both seasons(280 participants).Paired-sample t-tests,one-way ANOVA,and hierarchical stepwise regression are applied to identify the key driving factors.[Result]1)Winter anxiety-relieving efficacy declines by approximately 38.8％compared with summer,exhibiting a significant"seasonal healing deficit".Resilience varied markedly among space types,and open lawn space has the highest resilience(-28.3％)while high-density Metasequoia avenue space is the lowest in resilience(-57.8％);2)Driving factors display a"seasonal reversal".In summer,the green view ratio(Beta=0.512)is the dominant factor,contributed by plant color richness and water bodies.In winter,the healing is jointly driven by the positive promotion of sky view factor(Beta=0.485),the negative inhibition of branch visibility(Beta=-0.395)and bare soil coverage.[Conclusion]Winter healing in cold-region university campuses is constrained by insufficient solar exposure and high visual entropy,presenting the shift of restorative paradigm from"biophilic"in summer to"phototropic and order-seeking"in winter.3:4:3 evergreen/ornamental/deciduous stratified phenological structure,warm-toned hardscape interventions,and refined entropy-reduction maintenance are recommended to enhance the year-round seasonal resilience of cold-region campus landscapes.
