There are many factors influencing the process of dust deposition, such as features of the sand dust source areas, dust transporting distance, rainfall, and so on. Based on dust-fall data of ten cities in Gansu Province from 1986 to 2000, we analyzed the difference of dust-fall fluxes between desert/gobi area and Loess Plateau area, and illustrated the reasons that caused the difference. Results are as follows: (1)The dust deposition fluxes in arid area in Northwest China are major associated with dust event frequency; (2)The dust-fall amount in desert/gobi area is larger than in Loess Plateau area; (3)The dust deposition fluxes show high values in the major dust source areas and they reduce as the transportation distance increase when the dust transports from west to east.
Key words: dust deposition; dust event frequency; dust cycle
