Background technique

Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge and has good flexibility in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called a "water elastic city". The international term is "low-impact development of rainwater system construction", which absorbs water, stores water, seeps water, and purifies water when it rains, releases and utilizes the stored water when needed, and realizes the free migration of rainwater in the city. Starting from ecosystem services, building water ecological infrastructure across scales and combining multiple types of specific technologies to build water ecological infrastructure is the core of sponge cities.

Rain gardens are naturally formed or artificially excavated shallow concave green spaces that are used to gather and absorb rainwater from roofs or ground, purify the rainwater through the combined action of plants and sand, and make it gradually infiltrate into the soil, conserving groundwater, or It can be used to supply urban water such as landscape water and toilet water.
