Abstract The ozone concentration of 3 typical urban forests growing at foothill, river valley and ridge of Yuanshan Park in Shenzhen were observed for 24 hours in the summer of 2015. At the same time, the meteorological factors were also observed as influencing factors. Our results showed that:The mean value of hourly and 8h maximum ozone concentration in 3 forests were all achieved the primary standard of national air quality standards (160 and 100 μg/m3, respectively). The daily average ozone concentration in 3 forests were all higher than the control with the highest value observed at the ridge. The daily variation of ozone concentration in 3forests all exhibited a single peak curve, with the highest concentration occurring in 15:00~17:00pm, whereas the lowest occurring in 5:00~7:00am. The ozone concentration in each forest was positively related with the temperature and negatively with the relative humidity. Moreover, a positive correlation was noted between the ozone concentration and the wind velocity at the ridge. In conclusion, the air quality in 3urban forests of Yuanshan Park in Shenzhen is consistent with the air quality requirements of forest recreation activities, and the proper time according to the status of ozone is from 5:00 to 7:00 am in summer.
