Abstract: 【Objective】 This paper compared the ecological benefits between in and outside of a Phyllostachys pubescens recreational forest in order to provide a theoretical basis for evaluating its overall healthy function.【Method】 Environmental factors, such as air temperature, humidity, wind speed, illumination, particulate concentration and air oxygenation, were synchronously observed, and the ecological healthy function of the bamboo forest was evaluated.【Results】 ①Human comfort: compared with the square, the range of temperature drop in the forest was 8.60-12.50 ℃, and the range of temperature drop in the edge of the forest was 7.10-11.20 ℃. The daily mean value of relative humidity in the forest was 15% and 42% higher than that in the edge of forest and the square, respectively, and that in the edge of the forest was 31% higher than that in the square. The daily mean value of wind speed in the square was respectively 35% and 27% higher than that in the forest and on the edge of the forest, respectively. ②Airborne particulate matter: the daily mean concentrations of four kinds of particle size were highest in the square, and second largest on the edge of forest, with the lowest concentration being found in the forest. The daily mean value of TSP and PM10 concentrations in the three samples all belonged to the “middle” level. The daily mean value of PM2.5 concentration in the forest and on the edge of the forest belonged to the “clean” level. The daily mean value of PM2.5 concentration in the square belonged to the “middle” level. ③ Degree of oxygen-rich air: the average daily degree of oxygen-rich air in the forest was the highest, and ranged from 20.84% to 23.20%. The edge of forest was second, and ranged from 20.61% to 22.73%, the square was the lowest, and ranged from 20.12% to 21.91%. ④The tension sense of mice was decreased, and the exploration and cognitive ability of mice were all significantly enhanced after the Ph. pubescens forest treatment.【Conclusion】 Comparison of the forest margin and square in the summer bamboo forest indicated that the quality of the air environmental was better and more suitable for tourists to rest and relax.
