Abstract

The invention relates to the technical field of surface runoff control and utilization, in particular to a multi-objective optimization method for a surface runoff control and utilization scheme, and the method comprises the steps of building a current urban rainfall flood simulation model of a research area through an SWMM model; establishing a future urban rainfall flood simulation model of the research area on the basis of the current urban rainfall flood simulation model, and preliminarily estimating the scale of each measure according to a design scheme and a planning scheme; establishing a research area runoff control objective function; and establishing a research area runoff control scheme optimization model on the basis of the research area future urban rainfall flood simulation model and the research area runoff control objective function. According to the invention, the non-dominated sorting genetic algorithm and the SWMM model are combined, multiple low-influence development measure combinations of the same plot and the change of the flow length of the district are considered, a multi-target scheme optimization technology for retaining and storing the runoff, improving the runoff water quality and reducing the manufacturing cost is established, and technical support is provided for sponge city construction.

Description

technical field [0001] The invention relates to the technical field of surface runoff control and utilization, in particular to a multi-objective optimization method for a surface runoff control and utilization scheme. Background technique [0002] After urban construction, the impermeable area of ​​the surface increases, the water permeability decreases, and the infiltration of rainwater decreases, which will lead to the increase of surface flow after rainfall, the speed of confluence, and urban waterlogging and floods from time to time. Adopting the idea of ​​low-impact development or sponge city, through the construction of corresponding stagnation, infiltration, storage, purification, utilization, and drainage measures to increase infiltration, reduce runoff, slow down the speed of confluence, and control surface runoff pollution, it is an important way to alleviate urban flood control and waterlogging. It is one of the important ways to reduce runoff pollution and impro...
