Many studies have shown that urban green spaces can promote emotional health. Deciduous forest is an important landscape and ecological resource of the city. However, the emotional impact of different behavior patterns in this kind of natural space with obvious seasonal changes are rarely discussed. This study explores the emotional feedback of two typical behavior patterns within an urban landscape forest in autumn: sitting and walking. We recruited 80 volunteers and divided them into a sitting viewing group (group S) and a walking viewing group (group W). On the premise of gender balance, they were randomly assigned to a natural path under a Ginkgo biloba forest in autumn for 15 min of viewing. Physiological and psychological indicators were used for monitoring. Blood pressure, heart rate and electroencephalography (EEG) were used for physiological indicators, and a POMS questionnaire was used for psychological indicators. A paired t-test and one-way ANOVA were used to analyze the physiological parameters of the two experimental groups, and a paired Wilcoxon signed-rank sum test was used to analyze the differences in psychological indexes between the two behavior groups. The results showed that the diastolic blood pressure and pulse of the sitting group decreased significantly under the seasonal deciduous forest, and the walking group attained higher “Engagement”, “Excitement”, and “Relaxation”. In the absolute α and β waves, there were significant differences in the parietal P8 channels between the sitting and walking groups, and significant differences in the RAB indicators of the AF3, F7, P7, FC5, FC6, F3 and T7 channels. The two behavior patterns can effectively reduce negative mood, and the “Vigor” mood in the walking group was significantly increased, which was significantly better than that of the sitting group in reducing negative mood. These results enrich research on the influence on emotional health in the field of seasonal green-space restoration. The differences of different behavior patterns can provide guidance for planning urban landscape forest construction and activity facilities.

Good architectural space design can bring positive emotional stimulation and relaxation to users, but few studies have investigated the quantitative indicators in architectural space design and their impact on user emotions. This study takes the right-angle sandwich interface system in architecture as an example to guide the next vertical greening simulation experiment by comparing the spatial quantitative differences in connection value, integration degree, and population agglomeration. Eighty adolescent volunteers were recruited into a control (artificial decorative wall) and experimental (green wall) group based on wall type. We compared their physiological and psychological indicators, including blood pressure and blood oxygen, and psychological indicators, including POMS and SIAI-S scales. Then, we made predictive factor judgements on vertical green elements. The quantification of the interior space of the building showed consistency in parameter changes, with the central area being the area of connectivity, integration, and crowd aggregation values. After the experiment, the experimental group showed a significant decrease in diastolic blood pressure, systolic blood pressure, and heart rate (p = 0.00) and a significant decrease in tension, anger, fatigue, depression, and panic (p = 0.00). The quantitative relationship between vertical greening elements and emotional promotion using stepwise linear exploration shows that the “vine” element is a significant predictive factor for diastolic blood pressure, T-A emotion, and SIAI-S values. The results enrich the indoor optimization and creation expansion paths of interface systems for various spatial experiences and further provide guidance for urban indoor green construction plans and green landscape facility planning via the emotional influence of indoor vertical space greening on young people.
