The observation data from conventional observation instruments and single-band(525 nm)integral nephelometer, PM10 automatic monitor and visibility instrument of the Taklimakan Desert Atmosphere Observation Station in 2010 were used to analyze the relationship between the aerosol scattering coefficient and various factors in the Tazhong. The results showed that:(1) Scattering coefficient and mass concentration of PM10 had a significant positive correlation, and the correlation coefficient was 0.96 in autumn, 0.94 in summer, and 0.91 in winter.(2)For mass scattering coefficient, the lowest value was in March, the highest value was in October; the lowest value was 0.66 m2·g-1 in spring, the highest value was 1.386 m2·g-1 in fall. The mass scattering coefficient of Tazhong station was smaller than that of Zhangbei Station of Hebei Province, Minqin Station of Gansu Province, Xigu District of Lanzhou, Xilinhaote Station of Inner Mongolia, Crete Island of Greece and Negev Desert of Israel. (3) There were a significantly negative correlation between visibility and scattering coefficient, and the coefficient was 0.80. The correlation coefficient in summer, autumn and winter exceeded that in whole year. With correlation coefficients 0.913, 0.908, and 0.857,respectively, and the lowest value was in spring (0.723). (4)When the wind speed was large, the scattering coefficient values were relatively large, and the correlation coefficient was 0.45. When the scattering coefficient was less than 500 Mm-1, the wind direction was distributed in ENE and NE; when the scattering coefficient was more than 500 Mm-1, the wind direction was mainly distributed in ENE, NE and E. In the ESE wind direction, the average of the scattering coefficient was the largest, followed by the SSE direction, and the minimum value was the S wind direction.
