| Abstract: | Flow characteristics of viscous flow around a Nitraria tangutorum boscage were investigated by wind-speed instrument.According to two-dimensional of viscous flow around circular cylinder model,the velocity fields were analyzed with mean velocity contours and vector fields.Through different observation of type boscages,the effect of windbreak,and the mechanism of wind erosion were discussed. |
