- Abstract:
- In order to evaluate the effect of reducing wind velocity of different natural vegetation,5 natural shrub and grass vegetations,Caragana intermedia,Nitraria tangutorum,Calamagrostis epigejos,Leymus secalinus and Achnatherum sp lendens in the ecotone between the Kubuqi desert and the riverbank of the Yellow River were chosen and the uncovered sand was selected as the comparison.The results showed that the order of the effect(near the ground,0～10 cm) of reducing wind velocity from strong to weak was Leymus secalinus>Achnatherum sp lendens>Calamagrostis ep igejos>uncovered sand>Nitraria tangutorum>Caragana intermedia.And there was a big difference of the ratio of reducing wind velocity among different height of the same natural vegetation.As the height changing,the ratio of reducing wind velocity of different natural vegetation changed.
