Abstract
The present disclosure relates to water environment governance technology, and particularly discloses an urban river/lake water environment multi-interface governance and restoration method. The method is a multi-interface coordinated governance and restoration method based on 'control for bottom, regulation for middle and governance for top', including: 'control for bottom'—controlling the emission of sediment nutritive salts and the dormancy and recovery of algae; “regulation for middle”—regulating primary productivity in a water body to inhibit the recovery of the algae; and “governance for top”—reducing nitrogen and phosphorus nutrients of an air-water interface to control the reproduction and growth of the algae. In the present disclosure, the water body governance and restoration technology based on interface coordination can effectively inhibit the outbreak of cyanobacteria and avoid extreme conditions in the ecosystem.
