The application relates to the technical field of intelligent construction, and particularly provides a
sponge city design scheme optimization method and
system, which comprises the following steps: acquiring key parameters in a building
information model of a
sponge city, matching an initial scheme through a
rule engine, constructing water conservancy data based on the key parameters and the initial scheme, inputting the water conservancy data into a hydrodynamic model to output
simulation results of the
sponge city, comparing the
simulation results with preset target parameters, iteratively optimizing the initial scheme, and outputting an optimized design scheme meeting the preset target parameters, updating the building
information model based on node changes in a construction process of the sponge city, and generating a final design scheme based on the updated building
information model, so as to solve the problems of low design efficiency and insufficient rationality caused by the fact that the
construction design of the sponge city depends on manual work in the prior art.
