The invention discloses a river training method through wind. The method includes first arranging vertical shaft type wind high-pressure pumps at windward positions of jetty heads at two shores of the river every 1km to generate high-pressure gas, and delivering the high-pressure gas to the river bottom through a delivery pipeline which should be sunk to the river bottom longitudinally along the main flow direction of the river. The principle that a large amount of rising bubbles can be generated when the high-pressure gas is erupted from the river bottom is adopted, the bubbles can carry sand at a main channel of the river bottom to rise continuously, and the sand is difficult to deposit due to continuous generation of the gas and flows to the ocean without reservation under scour of the water flow. After a long time, underwater river beds can form a narrow and deep main channel at the position of the delivery pipeline, and surrounding silt collapses gradually towards the main channel direction along with continuous sapping of the channel until the whole channel saps.
