Urban green space is believed as a beneficial landscape for mental restoration in the urban settings. This study aims to examine the restorative quality of the urban green space from a multi-sensory perspective, focusing on both direct and indirect connections between visual, auditory, and tactile sensations and mental restoration. Two hundred and fifty park users of Tianhe Park in Guangzhou, China, were surveyed. Data were collected regarding their three types of sensations, i.e., the perceived mental restoration, health-related behavioral activities and emotional responses in the urban park. As a result, visual and auditory sensation were found to be linked with mental restoration directly and indirectly, while the tactile sensation was only associated with mental restoration indirectly; and health-related behaviors and emotional response mediated the relations between the three sensations and mental restoration significantly. It is concluded that the greater effects of auditory sensation and the under-studied potential effects of tactile sensation on mental restoration should be more emphasized in the future design of urban park. This is expected to contribute to the high restorative quality of the urban green space and promote public health.
