Abstract:
Characters of climatic potential of wind erosion and which effects on field environment have been revealed based on observation and analysis of field wind erosion and its effective factors in different soil patterns in dryland farming area of the north foot region of Yinshan mountain, Inner Mongolia. The effects of different types of strip intercropping, cereals with grasses, cereals with potato, and bush with grasses as well as stubble cover, on reducing wind erosion were observed and studied. It is pointed that there are better effects of strip intercropping on controlling wind erosion in dryland farming areas of the north foot region of Yinshan mountain where windbreak forest is difficult to plant. And the reasonable patterns of strip intercropping in different degraded fields and the series techniques of increasing yield have been made clear.
