Central Asia is located in arid and semi-arid regions. This region contributes to dust aerosols because of desertification and land degradation. In order to better understand temporal variability, vertical distribution, and potential diffusion characteristics of salt dust and desert dust in Central Asia, we studied the intranasal changes in dust aerosol from the Aral Sea basin and Taklimakan Desert using MODIS aerosol data and CALIOP data, and analyzed its potential seasonal diffusion from 2005 to 2015 using the HYSPLIT model. Results showed that AOD of this region was high in spring and summer and low in autumn and winter. Over the 14 years, it showed an increasing trend. The mean values of the four seasons were: spring(0.412) summer(0.258) autumn(0.167) ≈ winter(0.159). The annual AOD high value areas were mainly concentrated in the Tarim Basin in southern Xinjiang and surrounding areas of Aral Sea.The annual average value of AOD in Aral Sea was 0.278, and annual amplification was3.175%. It is indicated that the degradation of the Aral Sea had a direct impact on the AOD surrounding area. The annual average value of AOD in the Tarim Basin was 0.421, and annual amplification was 0.062%, which was mainly affected by temperature and wind speed, and the dominant factors were slightly different in different seasons. Dust aerosols were mainly concentrated in a range of 0-2 km. Aerosol depolarization ratio range in the desert(10%-45%)was slightly greater than that in the Aral Sea(15%-30%) and the aerosol color ratio range in the Aral Sea(0.3-0.8) was less than that of the desert(0.5-0.9). There were two high-frequency color ratios of 0.5 and 0.3 from the dust zone over 0-2 km and 4-6 km of salt dust. Compared to dust aerosols, salt dust aerosols had smaller irregularities and particle size, and higher impact of height range. As for the Aral Sea region, the potential distance and height of air parcel trajectories to the northeast were greater than to the west and south, whereas the air parcel trajectory proportion of the former was lower than that of the latter, which mainly affect Uzbekistan and Turkmenistan. Most of the dust in the Taklimakan Desert is still settling in the vicinity of the dust source region. The potential diffusion path to the eastern regions has impact on Qinghai, Gansu, Ningxia, Shaanxi and other regions.
