[Objective] The current situation and annual dynamic change of wind erosion on cultivated land in the Yellow River alluvial area of the Huaihe River basin were studied to provide a scientific basis for regional wind erosion research and control.[Methods] Lankao County

He'nan Province

was selected as the research area to interpret the land use information in 2018 and 2019 using high-resolution remote-sensing images. The wind erosion model of cultivated land was used to calculate the modulus of wind erosion

and the effects on wind erosion of cultivated land of annual land-use change were analyzed.[Results] ① In 2018-2019

the major type of land use at Lankao County was irrigated land

and the area of land use change was 21.40 km2. The dynamic degree of irrigated land was -1.54%. The main change in land use was from irrigated land to forest land (7.19 km2). ② The main wind erosion intensity on cultivated land at Lankao City was mild erosion

followed by light erosion. The erosion area was reduced by 17.04 km2

and the dynamic degree was -12.13%. ③ During 2018-2019

the changes in wind erosion on cultivated land at Lankao County were closely related to the changes in the area and spatial location of the irrigated land. The area of erosion reduction caused by the rotation of irrigated land was 3.36 km2

mainly located in Yifeng Township

Chengguan Town and other areas. The area increased by 0.98 km2 due to the transfer of irrigated land

which was mainly located in Yifeng township

Putaojia Town and other areas.[Conclusion] The characteristics of land use and wind erosion on cultivated land in the Yellow River alluvial area of the Huaihe River basin are distinct

and the changes in irrigated land directly affect cultivated land wind erosion. Therefore

more attention should be paid to controlling the wind erosion of cultivated land and using the cultivated land effectively.
