Disclosed is a method for controlling soil and water loss in a wind-water complex erosion region, which includes: randomly selecting a data acquisition reference point in a historical control area and acquiring a soil sample; detecting soil data of different soil layers on the soil sample, including soil viscosity, moisture content and organic matter content; selecting a plant sample, calculating a solid-binding coefficient of the plant sample and selecting an optimal soil-binding plant; fitting a relationship model; acquiring a control soil sample in a target control area of the wind-water complex erosion region, calculating a flatness and a soil and water loss coefficient u; setting a soil and water loss coefficient threshold u; and setting a planting density and optimal soil-binding plant type in the target control area. The present invention achieves the optimal soil and water loss control effect by considering soil-binding effects of different plants from multiple aspects.
