The effects of controlling wind erosion by strip intercropping with stubble were studied to solve the problem of serious wind erosion in the ecotone between agriculture and animal husbandry in the north area of Yinshan Mountains,Inner Mongolia.Through the measurements of the wind,land surface roughness and the amount of wind erosion,the effects of different heights of stubble on controlling wind erosion in stubble field and neighboring bare field were revealed to provide a theoretical basis for controlling wind erosion.Results showed that with the increased stubble height,wind velocity near ground decreased and the effect of high stubble(30cm)was the best.With the increase of measured height,the effect of stubble height on wind velocity decreased.Land surface roughness increased with the increase of stubble height.Compared with the control,the surface roughness in high stubble(30cm)field and neighboring bare field of high stubble increased by 466.67% and 126.98%,respectively.Wind erosion decreased with the increase of stubble height.Compared with the control,the amount of wind erosion in high stubble(30cm)field and neighboring bare field of high stubble decreased by 90.21% and 65.51%,respectively.Crop stubble can enhance not only its effect in controlling wind erosion,but also the protection of neighboring bare field.The effect of high stubble(30cm)on controlling wind erosion was best,and it also had the best protective effect on neighboring bare field.
