摘要

Taking the Phyllostachys heterocycla forest in Qishan National Forest Park of Fuzhou for example,this study observed the diurnal variation of atmospheric aerosol particles in the forest in the growing season.The results showed that:① The diurnal variation curves of the particle concentration of the forest and the forest edge had “two peaks and two troughs”,but the peaks and troughs of the forest edge were advanced or delayed.The concentrations of the particles in the forest and at the forest edge had two peaks at 11:00–13:00 and 17:00–19:00 and two troughs at 7:00–9:00 and 15:00–17:00.② For the forest and the forest edge,the diurnal variation trends of the particles of different particle sizes were generally similar,except that the peaks and troughs of fine particles were slightly earlier or lagging than that of coarse particles.③ The concentrations of the particles were positively correlated with temperature,humidity and light,and negatively correlated with wind speed,and the concentrations of the particles at the forest edge were significantly negatively correlated with wind speed.
