In order to investigate the properties and variation of dust aerosol transportation, the weather condition and pollutant characteristic that influenced air quality of Shijiazhuang on April 15^th, 2015 were analyzed. The HYSPLIT-4model was applied to analyze the back trajectories of dust aerosols. The ground-based micro-pulse Lidar and CE-318sun photometer measurements were used to study the vertical distribution of dust particles and its optical properties variation. In addition, it was compared with another case with strong wind but non dust aerosol deposition. The dust deposition effect on extinction coefficient was discussed. And the contribution of dust deposition to surface PM₁₀ concentration was evaluated. The results indicated that the major factor of rapid increase PM₁₀ concentration in Shijiazhuang was due to the long-distance transportation and deposition of dust particles from Mongolia by the direction of northwest. Dust deposition had an important contribution to both extinction coefficient and PM₁₀ concentration. The rapid dust aerosol disposition was consistent with cold front movement and cold air sinking over Shijiazhuang region. The whole process of dust transportation and disposition had been monitored by the micro-pulse Lidar. It was found that the dust particles mainly distributed on the height of 1500m to 3000m before sinking, where the extinction coefficient increased with the altitude. The process from dust transportation to deposition lasted long time, which could be regarded as one strong alarm signal for dust pollution. When the dust particles arrived over Shijiazhuang region, the aerosol optical depth, turbidity, and particle size showed larger values and the visibility decreased exponentially with the aerosol optical depth.
