Previous research has indicated that natural landscapes exhibit a greater capacity for ameliorating negative emotional states in individuals when compared to urban landscapes. Nevertheless, significant scientific inquiries, such as the uniformity of the rejuvenating effect across distinct categories of natural landscapes on college students and the choice of the optimal plant community for achieving the most potent restorative effect, remain unexplored. This study aimed to address these questions by selecting four plant communities (single-layer grassland, single-layer woodland, tree-grass composite woodland, tree-shrub-grass composite woodland) and using an electroencephalography method to capture the neuroelectric activity of the participants in combination with the Positive and Negative Affect Schedule score to explore the effects of plant community types on emotional recovery. The results showed that all four plant communities significantly increased positive emotions and significantly reduced negative emotions. There was no significant difference in the recovery effect of positive emotions among the four plant community types, but there was a significant difference in the recovery effect of negative emotions. The effect of tree-shrub-grass composite woodland on the negative emotion recovery effect is the best; the EEG results found that the alpha wave amplitude induced by the tree-shrub-grass composite woodland was significantly higher than that of the other three groups of plant communities, and the EEG and behavioral results were consistent. The results show that the tree-shrub-grass composite woodland has the best restoration effect and has stronger planning and design significance.
先前的研究表明，与城市景观相比，自然景观在改善个体负面情绪状态方面具有更大的能力。然而，一些重要的科学问题，比如不同类型的自然景观对大学生恢复活力效果的一致性，以及选择何种最佳植物群落以实现最强恢复效果等，仍未得到探索。本研究旨在通过选取四个植物群落（单层草地、单层林地、乔草复合林地、乔灌草复合林地），并结合积极和消极情绪量表得分，利用脑电图方法记录参与者的神经电活动，来探究植物群落类型对情绪恢复的影响。结果显示，所有四个植物群落均显著增加了积极情绪，并显著降低了消极情绪。四种植物群落类型在积极情绪恢复效果上没有显著差异，但在消极情绪恢复效果上存在显著差异。乔灌草复合林地对消极情绪的恢复效果最佳；脑电图结果发现，乔灌草复合林地诱发的阿尔法波振幅显著高于其他三组植物群落，脑电图结果与行为结果一致。结果表明，乔灌草复合林地具有最佳的恢复效果，具有更强的规划和设计意义。
