The concept and function of sponge city is a new generation of urban rainwater management concept, which means that the city can adapt to environmental changes like a sponge and cope with natural disasters caused by rain, and can also be called "water elastic city".
Its construction can effectively alleviate various water problems in the process of rapid urbanization, effectively improve ecological problems such as urban heat island effect, and create public spaces with ecological and landscape functions. It is a powerful means to restore urban water ecology, conserve water resources, enhance urban flood control capacity, expand effective investment in public products, improve the quality of new urbanization, enhance citizens' sense of acquisition and happiness, and promote the harmonious development between man and nature.
