Streets are important public spaces in daily life, and their stress-relieving abilities help to improve people’s physical and mental health. To investigate the effects of different types of street vegetation on people’s stress recovery, this study used virtual reality technology to establish five street scenes with different vegetation types, including a non-vegetated street, a street with trees, a street with trees and grass, a street with trees and hedges, and a street with trees, grass, and flowers. Twenty-four participants completed the Trier Social Stress Test and then watched the five street scenes for stress recovery. Participants rated the vegetated streets as significantly better at reducing stress than the non-vegetated street. Compared with the non-vegetated street, the participants’ POMS scores decreased by 2.59–12.09 and ROS scores increased by 0.83–3.67 after watching the vegetated streets, indicating significant improvement in mood (P < 0.001). HRV data showed that the combination of trees, grass, and flowers was the most effective for stress recovery (LF/HF = 0.67 ± 0.42; pNN50 = 27.41% ± 16.32%). EEG data showed that participants’ alpha power was 0.05–0.66 µV² higher and mental stress scores based on brainwave power were 0.23–0.37 points lower in the vegetated streets than in the non-vegetated street. The occipital and frontal regions showed the most positive responses to changes in vegetation elements, and alpha brainwaves in the O2 channel were the most active. Therefore, the streets with vegetation were more conducive to stress recovery than the non-vegetated street. It is thus suggested to integrate trees, grass, flowers, and other vegetation types along streets.

街道是日常生活中重要的公共空间，其缓解压力的能力有助于改善人们的身心健康。为了探讨不同类型街道植被对人们压力恢复的影响，本研究利用虚拟现实技术建立了五种不同植被类型的街道场景，包括无植被街道、有树木街道、有树木和草地街道、一条有树和树篱的街道，还有一条有树、草和花的街道。二十四名参与者完成了特里尔社会压力测试，然后观看五个街景以进行压力恢复。参与者认为植被街道在减轻压力方面明显优于非植被街道。与无植被街道相比，参与者的 POMS 得分下降了 2.59-12。P < 0.001）。HRV 数据显示，树、草和花的组合对于应激恢复最有效（LF/HF = 0.67 ± 0.42；pNN50 = 27.41% ± 16.32%）。脑电图数据显示，植被街道参与者的 α 功率比非植被街道高0.05–0.66 µV ^{2 ，基于脑电波功率的精神压力评分低 0.23–0.37 分。}枕叶和额叶区域对植被元素的变化表现出最积极的反应，O2通道中的α脑电波最活跃。因此，有植被的街道比无植被的街道更有利于应力恢复。因此，建议沿街道整合树木、草、花卉和其他植被类型。
