Restoration Evaluation of National Forest Park in Greater Khingan Mountains Region, China

As an important part of ecological civilization construction and harmonious coexistence between man and nature, the importance of restorative environment construction in national forest parks is self-evident. In this paper, the national forest park in the Greater Khingan Mountains region covering a large area of primary forest is taken as the research object. Based on visual perception, PRS, skin conductance level, and eye tracking technology are used as evaluation indexes to conduct restoration experiments on individuals. Among 60 participants, the PRS total scores for lawn space, shady space, dense forest space, and hard space were 166.63, 164.63, 168.43, and 158.93, respectively, indicating good restorative benefits, with hard space scoring lower. SCR decreases for dense forest space (M = 0.52) were significantly greater than for hard space (M = 0.38), suggesting better stress reduction. Eye tracking data showed that dense forest space had the longest total fixation duration (M = 42.57) and hard space the highest fixation count (M = 42.73). The results show that the national forest park is beneficial to the recovery of individual psychology and physiology, and can reduce the pressure of people’s visual perception. The psychological and physiological restorative benefits of different spatial scene types are different. Moreover, there is correlation between the eye movement index, psychological evaluation index, and physiological evaluation index, which confirms the possibility of introducing the eye movement index into the study of restorative environments.
