Health problems caused by modern lifestyle can be restored by environment, and the impact of national forest parks on human physical and mental health remains to be studied. In order to explore the impact of national forest parks on individual stress recovery under visual perception, 16 sites of national forest parks in the Greater Khingan Mountains region were taken as samples, and the restorability differences of different spatial scene types were analyzed with the help of subjective evaluation and physiological indicators. Environmental attention preference was assessed using eye tracking techniques. Psychological and physiological and eye movement experiments were performed on individuals. The results show that the national forest park in the Greater Khingan Mountains region has positive restorative benefits; Among the four spatial scene types, dense forest space has a more positive effect on stress recovery, and hard space has the worst effect, and individuals pay less attention to this space. Among the environmental elements, trees, shrubs, lawns and water bodies with high natural degree are the main environmental elements that individuals focus on, which can trigger people's positive emotions and reduce pressure. There is a significant correlation between total fixation duration and fixation count and individual subjective recovery, which can explain the degree of individual subjective recovery.
