| Abstract: | Based on the principle of energy conservation, the pattern of momentum flux(or friction velocity) in farmland windbreak network region is analyzed using data obtained from wind tunnel experiment and field observation. The evaluation model on the ratio of friction velocities between windbreak network region and grassland is given: With this model, the relative wind speed in windbreak network region is also analyzed. |
