Abstract: The ecological health factors inside and outside of Fokienia hodginsii forest in Fujian Province in summer including the daily variation of human comfort, airborne particulate matter, plant organic volatiles, etc. were studied and observed. Based on the oper field test (OFT), the impact of the environment in Fokienia hodginsii forest on human health was simulated. The results show that:(1) The daily mean values of light intensity, wind speed and temperature outside the forest were 21.35%, 29.46% and 31.28% higher than those in the forest, and the relative humidity was 6.52% higher than that in the forest, respectively; (2) The concentrations of TSP and PM10 outside the forest were 27.67% and 31.68% higher than those in the forest, and the concentrations of PM2.5 and PM1.0 were 60.46% and 58.82% higher than those in the forest, respectively;(3) The VOCs of Fokienia hodginsii forest were composed of 44 species, including alkane, olefins, alcohols, aldehydes, esters, ketones and other substances. The relative content of alkanes was the highest, while that of lipids was the lowest;(4) By comparing the mice treated by Fokienia hodginsii forest with the control group, it was found that the mice's total distance of exercise, total distance of central grid exercise, time and times of central grid exercise increased significantly. The mice's body weight increased but the number of fecal particles decreased, indicating that the overall ecological environment of Fokienia hodginsii forest in summer was better and the forest environment had good health care functions.
