[Objective] Water consumption of Artemisia ordosica through transpiration was measured and its responses to environmental factors were researched to provide some hints for construction of sand-fixing vegetations. [Methods] The dynamic transpiration of Artemisia ordosica was continuously measured using a large-scale weighing lysimeter, and the soil moisture content and related meteorological factors were synchronously monitored. [Results] Mean daily transpiration intensity of Artemisia ordosica performed a bimodal curve in sunny days; while in rainy days, the mean daily transpiration intensity performed unimodal curve. Water consumption of Artemisia ordosica was 101.66 mm during the study period, averaged 0.83 mm/d per day. Soil evaporation in the lysimeter was 106.05 mm, about 0.87 mm/d. The evapotranspiration accounted for 82.98% of rainfall in the study period. Transpiration intensity of Artemisia ordosica were significantly correlated with environmental factors of relative air humidity(p < 0.01), atmospheric temperature(p < 0.01), net radiation(p < 0.01), soil water content at 20 cm depth(p < 0.05) in a decreased rank. [Conclusion] Daily transpiration of Artemisia ordosica varied distinctly, and the transpiration rate was affected by soil moisture condition, meteorological factors and its own physical characteristics.
