Forest park is nature-led green space type that is closely related to people’s health. A tourist healthcare perception theory model of tourists is built with the help of tourism motivation theory, expectation difference theory and healthcare perception assessment theory. The samples are analyzed in Beijing Olympic Forest Park and structural equation model (SEM) is applied to verify this theory model. The results show that: Being close to nature, relaxing, escaping from reality andemotional needs all directly drive positive impact on satisfaction; satisfaction has directly impact on healthcare perception; being close to nature, relaxing have indirectly positive effect on healthcare perception through satisfaction. Therefore, it is necessary to improve recreational functional zones of forest park to meet the diverse tourism motivations, enhance the satisfaction of tourists to improve the healthcare perception by enhancing tourists′ natural and relaxing experience, so as to provide guidance for promoting social benefits as improving people health conditions.
