River ecological regulation method

The invention discloses a river ecological regulation method which comprises the following steps that: S1, bottom mud accumulated in a riverbed is cleaned, and sludge at the bottom is flushed with water; S2, a reservoir is establishedat the upstream of the river; S3, a water conditioning agent is put into the river, and surface layer, middle layer and deep layer treatment are carried out on the water in the river; S4, a filter material substrate is laid at the bottom of the river, emergent aquatic plants, submerged plants and floating-leaved plants are planted on the filter material substrate, the floating-leaved plants are located above the submerged plants, and the submerged plants and/or the floating-leaved plants are arranged between the adjacent emergent aquatic plants; and S5, unattended operation is achieved by installing on-line monitoring equipment, intelligent data transmission is achieved, meanwhile, water quality changes are manually and regularly inspected and monitored, correlation analysis is c
