这项研究说明了观看不同持续时间的视频对竹林具有不同结构的生理和心理影响。生理指标,包括EEG(脑电图),血压,皮肤电导,和脉搏,在180名中国大学生(平均年龄:20.72±2.56岁)观看竹子视频时进行了监测。在观看视频之前和之后,他们的心理指标,包括积极和消极的情绪,使用情绪状态概况问卷进行测量。看完不同持续时间的竹子视频后,所有生理指标仅在1分钟后对刺激做出反应。指标在1、3和5分钟时显示出不同的趋势。脑电图下降,然后在1分钟后保持在稳定水平,和高β,低β,α波在1、3和5min之间没有显着差异。3分钟后血压下降到稳定状态,3分钟后的下降幅度明显大于1分钟后的下降幅度。皮肤电导增加1至5分钟,并且它在长时间(5分钟)后没有稳定。脉冲在1分钟后降低,但在5分钟后增加。在观看了不同结构的竹子的视频后,生理和心理指标变化明显不同。皮肤电导显着增加(平均值:6.78%),更有效地减少了出汗量,从而减少紧张,当学生观看与单足竹林相比的交响乐竹林的视频时。冠层密度较高(0.83-0.85)的竹林可以显着降低α波(平均值:1.50Hz)。放松人体。高β波和低β波显示出更大的减少,更有效地减少紧张,当观察低倾斜率(<1.5%)的竹林时。草丛整齐的竹林可能会对人体产生更多有益的生理和心理影响。
This study illustrated the physiological and psychological effects of watching videos of different durations showing bamboo forests with varied structures. Physiological indicators, including EEG (electroencephalogram), blood pressure, skin conductance, and pulse, were monitored in 180 Chinese university students (mean age: 20.72 ± 2.56 years) while they were watching bamboo videos. Before and after watching the videos, their psychological indicators, including positive and negative moods, were measured using the Profile of Mood States questionnaire. After watching the bamboo videos of different durations, all of the physiological indicators responded to the stimulation after only 1 min. The indicators showed different trends at 1, 3 and 5 min. EEG decreased and then was maintained at a stable level after 1 min, and the high β, low β, and α waves had no significant differences between 1, 3 and 5 min. Blood pressure dropped to a stable state after 3 min, and the decline was significantly different greater after 3 min than after 1 min. Skin conductance increased for 1 to 5 min, and it did not stabilize after a long time (5 min). Pulse decreased after 1 min but increased after 5 min. After watching the videos with bamboo of varying structures, the physiological and psychological indicators showed significantly different changes. Skin conductance significantly increased (mean value: 6.78%), and the amount of sweat was more effectively reduced, thereby reducing tension, when the students viewed videos of sympodial bamboo forests compared with monopodial bamboo forests. Bamboo forests with a higher canopy density (0.83-0.85) could significantly decrease α waves (mean value: 1.50 Hz), relaxing the human body. High β and low β waves showed greater decreases, with tension reduced more effectively, when bamboo forests with a low tilt ratio (< 1.5%) were viewed. Bamboo forests with neat undergrowth could have more beneficial physiological and psychological effects on the human body.
