The environmentally responsible behavior of tourists has been one of the focal points in the field of sustainable tourism research in recent years. Taking Guangzhou City Park as an example, this study investigates the relationship between restorative perception, place attachment, and environmentally responsible behavior of urban park recreationists by constructing the theoretical framework of "cognition-emotion-behavior" of recreationalists via online questionnaire surveys and using the test method of structural equation mode. Studies have shown that: (1) When the restorative perception of the environment is compatible, malleable, and attractive, the recreationist will produce environmentally responsible behavior. Meanwhile, when the environment has a sense of distance and compatibility, it will promote the active environmentally responsible behavior of tourists; (2) the path of perceptual environmental compatibility in the restorative perception of recreationists being → place dependence→ place identity → environmentally responsible behavior has a positive impact on environmentally responsible behavior; (3) place attachment has a significant positive impact on environmentally responsible behavior. This paper suggests that urban park management governors should focus on improving the charm and attractiveness of parks, diversifying recreational activities, and creating emotional attachment places, so as to promote the development of urban parks and meet the diverse needs and experiences of park recreation.
