Abstract Field experiments of throughfall for Artemisia ordosica shrubs are carried out in Mu Us sandy land from May to September 2012 to analyze the characteristics and the influence factors of the throughfall for A.ordosica shrubs. The percentage of the average throughfall in the bulk precipitation for A.ordosica shrubs is 72.3%, among which the average throughfall for the shrubs with deadwoods is 69.3% that is less than the 75.3% for the shrubs without deadwoods. One of the reasons might be that the soil moisture decreases after the aging of the A.ordosica shrubs. Amounts and space distribution of throughfall under an A.ordosica shrub are influenced by the differences of deadwoods and radiation distances. Meanwhile, meteorological factors-such as precipitation, wind speed and direction have important influences on the throughfall for A.ordosica shrubs.
