[Objective] The main influence factors of wind erosion amount and their interaction on cultivated land in flooding area of Yellow River were studied to provide preferences for wind erosion prevention and cultivation measure improvement.[Methods] Through field observation and the collection of wind erosion data, we conducted a path analysis for the main impact factors of wind erosion to cultivated land.[Results] The wind speed cumulative time, crop coverage, and roughness were the main factors affecting the wind erosion of cultivated land. According to the direct path coefficients, the rank of influence factors was wind speed cumulative time > roughness > crop coverage. Referring to the indirect path coefficients, the rank of the indirect influence factors was roughness > crop coverage > wind speed cumulative time. The rank of wind erosion decision coefficient were d_w·w(determination coefficient of wind speed cumulative time and wind speed cumulative time)>d_w·c(determination coefficient of wind speed cumulative time and crop coverage)>d_w·r(determination coefficient of wind speed cumulative time and roughness)>d_c·r(determination coefficient of crop coverage and roughness)>d_c·c(determination coefficient of crop coverage and crop coverage)>d_r·r(determination coefficient of roughness and roughness). The wind speed cumulative time and the coverage of crops directly affect wind erosion and roughness act mainly through indirect effect to reduce wind erosion.[Conclusion] To reduce the risk of wind erosion, we can appropriately increase crop planting density and enlarge crop coverage and roughness.
