| 知觉恢复量表(PRS)在恢复性环境评价中有广泛应用，其中文版在城市公园景观评价中的应用尚未予以验证。以城市公园为单一评价对象，探讨中文版PRS量表的信度和效度。选取城市公园中具有不同要素、开敞度和场景的6个空间类型，分别录制成景观视频作为实验素材。共有120名男女比例为1:1的在校大学生参与了测试，在经历口语考试的压力后，通过观看城市公园的一个场景视频缓解压力，采用中文版PRS量表对场景的恢复性进行评估。结果表明中文版PRS量表在城市公园恢复性评估中具有良好的评估者间一致性和内部一致性；量表条目的代表性与适宜性程度较高，与注意力恢复理论的构架基本一致，对不同环境有一定的区分度，可用于城市公园恢复性环境评估。 |

| Experimental Study of the Perceived Restorative Scale (PRS) in Chinese by Evaluating the Restorative Qualities of Urban Park Scenes |

| Abstract: |
| The Perceived Restorative Scale (PRS) is widely used in restorative environments evaluation. As its Chinese version hasn't been tested in landscape evaluation of urban parks, this paper studied the reliability and validity of the Chinese PRS in evaluating the restorative qualities of scenes in urban parks. Videos of scenes with different elements, openness, with or without people were taped. Altogether 120 college students, with an equal number of males and females, participated in this experiment. They first took an oral English test as a stressor, and then watched one of the six landscape videos for stress recovering. Subjects rated the Chinese PRS based on the scene they watched. The results showed the Chinese PRS had a high inter-rater reliability, and the internal consistency reliability was acceptable. The correlations between the overall score and scores of the items were significant. According to the result of the exploratory factor analysis, the scale construct was generally coherent with the Attention Restorative Theory. The rating results also showed there were significant differences between different urban park scenes. It suggests the Chinese version of the PRS can be used in evaluating restorative qualities of urban park landscapes. |
