The anxiety disorder among students in modern public space design has become a common phenomenon, which can affect their learning efficiency and life health. Therefore, it is necessary to study the theoretical basis of environmental psychology on the relationship between environment and anxiety and explore the impact of humanistic environmental landscape design on modern public space design students’ anxiety disorders from the perspective of psychology.

The study used a questionnaire survey method to collect environmental factors that trigger students’ anxiety and obtained a ranking of the importance of environmental factors through quantitative analysis. The impact of environmental characteristics such as physical environment, visual landscape, and spatial scale of buildings on students’ anxiety disorders was analyzed through on-site research. The effectiveness of humanistic environmental landscape design from the perspective of psychology was tested using the Svell building ventilation software in Computational Fluid Dynamics (CFD). Simultaneously using the State Anxiety Inventory (SAI) to detect students’ anxiety.

From the perspective of psychology, the humanistic concept of odor, ventilation, and heat and humidity has been optimized and designed to create a spatial environment conducive to alleviating students’ anxiety. It can effectively reduce anxiety caused by poor ventilation and prevent aggravation of anxiety due to high humidity and odors.

The humanistic concept of environmental landscape design from the perspective of psychology has a positive impact on students’ anxiety disorders in modern public space design.
