Sponge city rainwater runoff intelligent regulation and control method coupling multiple elements

The invention discloses a sponge city rainwater runoff intelligent regulation and control method coupled with multiple elements, which is characterized in that a rainwater runoff regulation and control strategy is optimized in three dimensions of a space layer, a simulation layer and a control layer, multiple elements of a sponge city system are transformed through regulation and control facilities and intelligent scheduling, and the transformation scale and economic cost of infrastructures can be reduced. Through two modes of a rule-based control strategy and a model prediction control strategy, rainfall information, a liquid level condition, a flow condition, waterlogging overflow and other system states are considered, a sponge facility, a pipe network system and other factors are coupled, a rainstorm flood management model is combined to construct a hydrological and hydrodynamic model, and finally an optimization control strategy is determined. And evaluating the effectiveness of the intelligent regulatio
