The two types of simulated sand-fixing shrub such as no-leaf-shrubs and leaf-shrubs were made up according to sand xeric shrubs configuration, and their effects on change of wind velocity was observed in ourdoor. The results showed that the reducing ratio of wind velocity increased with the increase wind velocity at the height of 40 cm with wind velocity of 2.2~5.5 m/s. The ratio of reducing wind velocity of the simulated shrubs was less than that of Artemisia arenaria, but not statistical significance. The ratio of reducing wind velocity of simulated leaf-shrubs was bigger than simulated no-leaf-shrubs. Simulated sand-fixing shrub has the remarkable function to control wind velocity because it is combined with the advantage of various vegetation, it is a optimized vegetation measure for controlling sand.
