In this study, we attempted to analyze the effect of color and temperature changes in the forest environment over time on the mood and physiological state of university students. The survey was conducted four times considering forest changes such as new leaf appearance and growth, autumn leaf changes, and fallen leaves. The participants' moods and physiological states were first evaluated in an indoor environment; a second evaluation was conducted after contact with the forest. The color visual information of the forest environment was analyzed through color extraction from photographs taken each survey day. The participants' moods and physiological states were measured using the Korean Profile of Mood States-Brief and a heart rate variability measuring device, respectively. Changes in the forest experience according to the season had an effect on university students' mood states. In particular, the effects of the spring forest experience included the relaxation of tension and the activation of vigor. This result is considered to be influenced by factors such as the season's temperature and the green color, which is predominant in the spring forest. However, no physiological changes were found in the participants according to each season. The results of this study can lead to greater consideration of the role of color in urban forest planning for universities and other public spaces.
在这项研究中，我们试图分析森林环境中颜色和温度随时间的变化对大学生情绪和生理状态的影响。该调查考虑了新叶出现和生长、秋叶变化和落叶等森林变化，分四次进行。首先在室内环境中评估参与者的情绪和生理状态；然后在与森林接触后进行第二次评估。通过从每次调查日拍摄的照片中提取颜色来分析森林环境的颜色视觉信息。使用韩国心境状态简表和心率变异性测量设备分别测量参与者的情绪和生理状态。根据季节的森林体验变化对大学生的情绪状态有影响。特别是，春季森林体验的影响包括缓解紧张和激活活力。这一结果被认为受到季节温度和春季森林中占主导地位的绿色等因素的影响。然而，根据每个季节，参与者的生理变化并不明显。本研究的结果可以促使人们更加重视颜色在大学和其他公共空间的城市森林规划中的作用。
