The invention provides an ecological sedimentation bed used for the restoration of slow-flowing rivers. The ecological sedimentation bed is a right-angled triangle structure, and the hypotenuse is arranged on one side of the bank of the river and along the river bank; the first right-angled side of the ecological sedimentation bed is arranged on At the upstream of the river, the first right-angle side is set at a preset angle with the river bank; the second right-angle side of the ecological sedimentation bed is set at the downstream of the river. In the present invention, the ecological sinking bed is designed as a right-angled triangle shape, and the hypotenuse is fixed on one side of the river bank. Leading to the main channel of the river, so as to reduce the impact of water flow on the sedimentation bed, maintain the stability of the sedimentation bed structure and slow down the erosion of the river bank by the river; the second right-angle side is set at the downstream of the river to form a slow flow or still water area, which is beneficial to aquatic life. Biological foraging, resting and avoiding danger, this ecological sedimentation bed can induce the water flow to take a curved form, and promote the formation of a meandering form of deep pools and shoals in the river.
