Abstract: Walking has been proved to have a positive impact on public health. As an important place for residents to carry out walking activities, urban park road environment characteristics have direct or indirect impacts on walking, behavior, psychological perception and population health. The road environment of Chengdu Huanhuaxi Park and Dayuan Central Park was taken as the research object, and three types of characteristic elements of nature, perception and facilities were extracted. Based on the theory of health restorative effect, the data were obtained by relying on the field environmental questionnaire survey. Finally, through regression analysis, seven restorative key feature elements of main roads were screened out (natural feature elements: richness of plant color, number of flowering plants; facility feature elements: number of recreational facilities, hardness of pavement; perceptual feature elements: sense of nature, spatial suitability (D/H) ratio), and road alignment), and there were 5 key characteristic elements of the secondary road restoration of the urban park (natural characteristic elements: lawn covering form, richness of plant species; facility characteristic elements: diversified aesthetics of pavement; perceptual characteristic elements: spatial suitability (D/H) ratio, and tranquility and ease), and there were 8 key characteristic elements of path recovery in urban parks (natural characteristic elements: flowering plants, waterscape, terrain richness; facility characteristic elements: pavement flatness; perception characteristic elements: road alignment, shade degree, spatial interface density). Through the analysis of demographic characteristic data, it was concluded that: (1) Age has an impact on the restorative effect and the score of characteristic elements. (2) The residence time has an impact on the restorative effect and the evaluation of perceptual characteristics. (3) In the most expected decompression activities, people who choose relaxation, thinking and leisure sports will have differences in the scores of natural characteristics.
