Abstract
- With the Fokienia hodginsii forest in Qishan National Forest Park as the object of study, this study observed the diurnal variation of concentrations of atmospheric aerosol particles inside and outside the forest, collected the data of microclimate factors, and analyzed their correlation with the particle concentration. The results showed that the diurnal variation curves of the particle concentration of the forest and the forest edge had two peaks and two troughs". There were two peaks throughout the day at 13:00 and 19:00 or 17:00 as well as two troughs at 7:00-9:00 and 15:00 or 17:00. The atmospheric aerosol particle in the forest was mainly fi ne particles, while the forest edge was dominated by coarse particles. For the forest and the forest edge, the diurnal variation trends of various atmospheric aerosol particles were similar. The particle concentration was positively correlated with temperature, relative humidity, and illumination intensity and negatively correlated with wind speed, and the particle concentration outside the forest was significantly negatively correlated with the wind speed.
