Abstract: An open-field experiment was conducted to analyze the impacts of the environment on the behavior of mice. We observed the behavior of mice in four different forest environments,including bamboo forest, conifer and broadleaf mixed forest, Cunninghamia lanceolata forest, and broad-leaved forest. The results showed that the total movement distance of the mice in each forest type was over 45% higher than that of indoor environment (CK), with no significant difference among the four forest types. The central grid movement distance of the four groups was over 50% higher than that of the CK. The four treated groups spent 63% more residence time in the central grid than that in the CK. There was no significant difference in central grid entering frequency among the four groups and the CK. The four groups had 8% higher standing frequency than the CK. There was no significant difference in body mass between the four groups and the CK. The CK group had the highest number of fecal particles (169.3), and the mixed coniferous and broad-leaved forest had the lowest (112.3). Relative humidity had a positive correlation with the number of fecal particles and body mass. Air pressure was positively correlated with the total movement distance, and significantly negatively correlated with the number of fecal particles. Wind speed was negatively correlated with the number of fecal particles and central grid entering frequency. Negative air ions were positively related to the total movement distance. In conclusion, the four forest environments promoted the behaviors of mice with different degrees of promotion. Conifer and broad-leaved mixed forest had the best effect on mice’s exploring ability and relieving pressure.C. lanceolata forest had the strongest effect on improving mice vitality. We suggest that people should choose forest environment for health care activities according to their needs.
