Impacts of Land Use Type on Soil Wind Erosion in Agro-pastoral Area
[Objective] Impacts of land use type on soil erosion in agro-pastoral area were researched to provide a scientific basis for the rational use of land resources
including the farming and management in arid desert area.[Methods] Soil erosion status under different land use types were tested by field erosion experiments and analyzed by meteorological data.[Results] Land use type significantly affected soil erosion.For artificial grasslands
Leymus chinensis reduced erosion remarkably than Alfalfa grassland did. In natural grasslands
marram grassland reduced more amount of erosion than Humilis grassland did. Artificial grasslands significantly reduced soil erosion than natural grasslands did. Ploughed field had the highest erosion in farm lands
untillage corn field without stubble reduced wind-erosion 46.7%~48.6% as compared with the ploughed field. Stubble crops reduced soil erosion remarkably
although it was different for different crop types. Stubble corn field reduced soil erosion 58.1%~63.5% than the ploughed field did. Stubble buckwheat reduced erosion 50.5%~54.6% as compared with the plowed slope. In different terrains
windward soil erosion was as high 3.12~3.73 times as the value of leeward slope.[Conclusion] Artificial grassland should be increased in the area. Whereas
fields should not be ploughed or should be reduced for the ploughed area in winter and spring seasons; the reclamation of windward land should be diminished; fields should be covered in the winter or stubble should be retained after harvest to protect topsoil from wind erosion.
