With the development of urbanization, the urban impervious area has increased rapidly, leading to serious rainwater problems such as the increased risk of urban flooding and runoff pollution. Meanwhile, there has also been severe impact on water safety and water environment at watershed scale. Therefore, the urban stormwater management model based on watershed management has developed rapidly in recent years. By analyzing the changes in the peak flow rate and the pollution load of the stormwater runoff before and after the development of the urban land, a management and control method for sponge city construction was put forward at basin scale, which was constrained by the peak flow rate of the flooding way and the self-purification capacity of the water environment. A multi-level stormwater control approach was put forward based on water quantity and quality control, and the stormwater management model of land sustainable development was proposed at the watershed-urban scale. Taking a development area as an example, the construction approaches of regional total runoff volume control, peak flow rate reduction, and runoff pollution control were analyzed, aiming at providing support for the overall coordination of watershed management and sponge city construction in the future.
