Sponge city refers to a city that, like a sponge, has good "elasticity" in adapting to environmental changes and responding to natural disasters. It absorbs, stores, seeps, and purifies water when it rains, and "releases" stored water when needed. And use it.

I. Sponge strategy in urban residential areas The landscaped land in residential areas should be considered in combination with sponge urban design methods. In a limited area of greenery, strategies such as infiltration, detention, and purification should be used to alleviate flood disasters in urban residential areas. 1. Traditional residential area-the rainwater garden in the traditional residential area The green space in the traditional residential area can be transformed into a sunken residential rainwater garden to collect rainwater from the surrounding hard paving.

2. Traditional residential area-parking lot Rainwater garden The parking lot in the traditional residential area can be transformed into a permeable grass-brick bioretention zone to collect the surrounding rainwater.

3. Traditional residential area-event venue

Tree ponds in traditional residential areas can be transformed into stranded ecological tree ponds to collect rainwater from open spaces.

Second, the green roof sponge strategy When the rain floods, runoff from the building roof is one of the important reasons leading to urban waterlogging. Therefore, transforming the city's building roof into a green roof can effectively alleviate the urban rainwater runoff pressure. On the one hand, collecting and storing rainwater through the sponge city structure, and using rainwater for irrigation, can save various energy consumption; on the other hand, the green roof will form a good urban landscape and increase the overall greening rate of the city.
