Using sounding data, surface meteorological data and particle size concentration, the planetary boundary layer height(PBLH) was calculatedand its change characteristic with particle size concentration were compared. Diurnal and seasonal PBLH variation characteristics are based on Nozaki method which is evaluated by Liu method, daily maximum and minimum PBLH are determined by Holzworth method. Results show that:Nozaki method is valuable for the diurnal and seasonal variation of PBLH though substantially overestimate stable boundary layer which can be compensate by Holzworth method. Daily maximum PBLH occurs during 11:00(Beijing Time, hereafter the same)to 16:00, and seasonal maximum PBLH is during spring attributing to annual maximum wind speed. PM2.5, PM1.0 and PM10 mass concentrations are negatively correlated with PBLH for interannual, annual, and seasonal time scale. Content of PM2.5 in PM10, PM1.0 in PM2.5 and PM1.0 in PM10 show notable monthly variations indicating Xi'an city also affects by upwind windy and dusty weather besides local pollution sources.
