Evaluation of psychological health environment factors in underground commercial space
Studying the psychological health environment factors of underground commercial spaces is an im-portant entry point for promoting urban sustainable development.Based on the grounded theory,this study qual-itatively analyzes and summarizes the environmental factors that affect the psychological health of underground commercial spaces.It constructs an evaluation index system consisting of four elements layers including spatial creation,environmental atmosphere,perception of information acquisition,and work experience,with 17 initial elements.The study evaluates the Xinzhongguan underground commercial space in Beijing.The results are as follows:(1)In terms of culture,atmosphere,and psychological perception,the attractiveness and satisfaction are high and need to be improved.The satisfaction with the surrounding environment,information acquisition,and process experience is good,but the attractiveness is weak and needs to be maintained and optimized.Sensi-tivity to comfort,decoration,etc.,is low and can be maintained with basic attention.Design effects,spatial char-acteristics,and indoor environment satisfaction are low and need to be improved.(2)Poor lighting environ-ment,monotonous entrance space,unclear edge division,lack of signage and natural elements will reduce the space recognizability and may cause psychological discomfort for the staff.It is necessary to optimize the psy-chological health environment of underground commercial spaces by improving artificial lighting,enhancing landscape design,incorporating natural elements,and enriching the color atmosphere.
