Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater, and can also be called "water elastic city". The international term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, seeps, and purifies water, and “releases” the stored water and makes use of it when needed. To build a sponge city, there must be a "sponge body". The urban "sponge" includes not only water systems such as rivers, lakes, and ponds, but also urban supporting facilities such as green spaces, gardens, and permeable pavements.
