The invention discloses the salt rinsing and pressing technology for a landscape water body and water power in coastal saline soil. The technology comprises the following step: aiming to the characteristics of large viscosity of the soil with a landscape river channel, poor air permeability, high salinity (25000 to 38000mg/kg) and serious soil secondary salinization in the coastal saline soil, byinjecting high-salt reclaimed water (salinity of 4000 to 6000 mg/L) in a sewage disposal plant into the river channel, the influent flow is controlled, and the water power salt rinsing and pressing lis performed to the river channel. Therefore, the purpose of reducing the soil salinity of the substrate of the river channel is achieved, and the foundation is provided for ecological restoration with the subsequent landscape river channel.
